Rewards Program Terms and Conditions
Last updated January 1st, 2020
Opting-in to Moosejaw Rewards:
All users must accept these terms and conditions and create an account with Moosejaw to opt-in to the program and earn, accrue, retain and redeem Moosejaw Reward Dollars (MJ$). The program is FREE to join and membership is ongoing until or unless the user requests to be removed or is removed due to abuse of the program. Users can opt-in to the program while checking out on Moosejaw.com or at one of our stores or at any time within 30 days of purchase to accrue the MJ$ earned on that purchase. Once opted-in to the program, MJ$ will earn and accrue for redemption as described below until the MJ$ expire or the user leaves the program.
All information collected and used to facilitate the Moosejaw Rewards program is directly related to the program's ability to provide value to the customer. A customer opting-in to the Moosejaw Rewards program is a separate action from establishing a user profile as a result of making a purchase.
The program opt-in requirement was added on August 6th, 2019. Existing program members prior to that date must still formally opt-in and accept the terms and conditions to continue to retain, earn and redeem MJ$. Pre-existing program members that fail to opt-in prior to June 28, 2020 will be removed from the program, and any unused MJ$ will be voided. We really, really don't want to that to happen, so please opt-in or we'll feel terrible.
Leaving Moosejaw Rewards Program:
You may choose to leave the Moosejaw Rewards program at any time by logging in and clicking on the “Opt out Rewards Program” link within the My Account Summary page, Email, calling 877-MOOSEJAW (877-666-7352) or in-store with help from our employees. If you leave the rewards program, any unused MJ$ will be voided upon completion of your request.
Earning MJ$:
All items we sell are eligible with the exception of gift cards or other items specifically noted. Full-priced items earn 10% back while discounted items earn 2.5%. "Discounted items" includes items on sale or discounted via coupon code or use of MJ$. You do not earn MJ$ for shipping or tax charges, only from the item value. MJ$ expire two years after earning and are redeemed on a first-in, first out basis (in other words, we always use your oldest MJ$ that are closest to expiration).
Checking & Redeeming MJ$:
On Moosejaw.com, just sign-in on any page to see your available balance. Once signed in, you will see your available MJ$ and maximum that can be redeemed in the payment section of the checkout process. In stores, provide the email address attached to your account to learn your balance and apply to your purchase. We will also send you a monthly email that details your balance and other account activity. This is a transactional email that you will receive even if you are not subscribed to our marketing emails.
Bonus Rewards Promotions:
Every so often, we'll have special offers where you can earn bonus MJ$, like an additional 10%, 20% or 40% back. So if we are running a 50% back special offer, and you buy a regular-priced item for $100.00, you will receive MJ$10.00 in base points, and a bonus of MJ$40. These special offers may have a cap on how many bonus MJ$ you earn during the promotion, but you will always earn the base Reward Dollars. Make sure to check us out on our social channels for other ways to win some extra MJ$!
MJ$ on Gift Cards:
You don't get earn MJ$ when you buy a gift card, but you do get MJ$ when you spend a gift card. Sorry gift givers. You're welcome gift receivers.
Product Returns and MJ$:
If you return an item, we deduct the MJ$ earned on that item from your balance. If you used the MJ$ and your balance is less than deduction, then your refund is reduced by the difference.
Program Abuse:
The intent of the program is to provide our loyal customers with a way to buy great gear for less. Moosejaw reserves the right to remove any user from the program and zero out their MJ$ balance if Moosejaw determines that the user is abusing the program by buying for resale, attempting to game the program or any other reason at Moosejaw's sole discretion.
Are you Sure?
Our Rewards Program is completely FREE and easy to use.
By opting out, you forfeit all the Moosejaw Rewards Dollars your currently have in your account, which is basically throwing away free money. What would your grandmother say about that? If you're 100% sure, please click "OptOut" below.
Earn 10% back on all full-priced purchases on Moosejaw.com or at our shops (2.5% for discounted items).
The program is FREE. Just register and join during the checkout process. So Easy.
After joining the program, you'll receive your MJ$ as soon as your order ships. Then the next time you shop at Moosejaw, you can redeem those MJ$ to get awesome gear for way less.

Special order items take longer to ship
We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Customer ServiceI can't really review the pack I purchased since it arrived with a broken chest strap. But the customer service seemed great. They offered me free shipping to return it and were willing to extend the discounts I received (It was crazy cheap with the discounts), but I chose to go through the manufacturer(Osprey) and just get a replacement strap. Overall great customer service and appealing corporate identity. Only four stars because it did arrive with a broken strap. But I like these guys!

great backpackI bought this for my son and he loves it. The one complaint that he has is that Osprey did away with the hip pockets, for some strange reason. He said they were very useful and should be returned to the design. Other than that two thumbs up.

Full featured packI purchased this pack for it's ventilation and (almost too many) features. I specifically like the ability to remove the top pocket, and the large side and back pockets. Several of my hiking buddies have the older version of this pack. They speak highly of it. I'm sure I will as well. I would suggest sizing one size up from Osprey's fit info. I measure at the mid to upper end of a Small; the Medium fits me fine.

Top Shelf Backpack!I purchased this backpack a few months ago and have taken it into the back country a few times since. I love it! The backpack is well designed with adjustment straps in every location so that you can make it fit you like a glove. Its light weight and if you have highly compressible UL gear, you should have no problem fitting it in the 48 liter compartment (non-UL gear will not fit in it so don't buy it for camping if some of your gear is not UL). The backpack is also tough as I hiked it through some really tough terrain and it held up great. I also purchased an Osprey 3 liter water bladder to go with it and love the design of the water bladder as well. I also like the side pockets that allow you to store your longer items such as trekking poles, fishing rods, etc. If I had to mention any negatives, for me they would be that I probably could have used a 54 liter because I pack in gear for my dog as well and that extra space would give me just a little more rooms for that extra gear. With my dogs gear and my UL gear, I can just barely get it into this pack for a 4-5 day hike-in camping trip. I would not want to go much larger though because a bigger pack might make me more apt to bring gear I don't really need. Also, I would not mind having another pocket or two on the outside of the pack to store items that I need to access easily during the hike without having to store all of those items in the top shell.

Great Lightweight Pack without SacrificeI have owned successive generations of the Exos line. Bought the first Exos 58 the year it came out, added the newer Exos 48, and then this year added the Eja 48 and 58 for my wife (so, I guess I have all three generations). In the world of lightweight, you can always go lighter - but at a certain point you need to think about the comfort of the ride. Used my 48 on a 6 day trek with no resupply (lots of food) - and it handled the volume easily. Durable and rugged - I use it for the backrest as part of my chair set up at camp. One small miss - putting the hydration bladder right against your back makes for some very warm water by mid day - so I always just place my bladder on top of my gear to keep it cool longer. The pockets on the hip belt are a huge help - not sure why they disappeared in Version 3 - but my wife just put her snacks in her shirt pocket. With over 1,000 miles on the combination of packs the quality is good and never needed a bush fix - Would I buy again? Well, I did - so yes. Recommend you do as well.

Best ultralight pack vs the others out thereThis is an outstanding ultralight pack which is a surprise coming from such a large company as osprey but one must give credit where credit is due I am an ultra-light Backpacker travels along the PCT and this pack is as good if not better then all of the other ultralight backpacks that are out there because for just one additional ounce of weight versus the other ultralight packs out there, you get an extreme amount of additional comfort and features. To have all of the stuff pockets, water bladder capacity etc etc, PLUS the frame support, this pack just cannot be beat. Such a great pack.

I want my pockets back!I so badly want to buy another Exos but just can not buy this new model. The previous model was about as perfect as could be. Everyone seems perplexed by the loss of the hip pockets and it makes NO SENSE to take those away. Although I would love to buy this pack again I just can't do it without the hip pockets. It's such a simple but convenient feature that adds no significant weight. OSPREY PLEASE BRING BACK THE EXOS POCKETS!!!!!!!! The current Exos is NOT an improvement over the older model.

Please note that the info provided above refers to the Torso Size / Length the pack will fit, and NOT any dimensions of the pack. Below are steps for how to measure your torso length. You should have someone help take this measurement for you so it is accurate.
HOW to MEASURE TORSO LENGTH: 1. Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt. 2. Touch your chin to your chest to find the C7 vertebrae, the knobby bone at the base of your neck. 3. Make sure you keep your back as straight as possible while measuring. 4. Measure the full length from the C7 vertebrae to the iliac crest. This torso measurement determines what size Osprey pack you should carry. Refer to the size chart above to find your ideal size. 5. If you are in between sizes, it is ideal to try them both on before ordering.
HOW to MEASURE CHEST MEASUREMENT: Measure around the fullest part of the chest.

Warranty Info
ALL MIGHTY GUARANTEE - Osprey's Lifetime Warranty
When Osprey celebrated their 35th anniversary in 2009 they launched The Osprey All Mighty Guarantee. What that means to you is ANY Osprey product purchased at ANY time is covered. Any product, any reason, any era - the all encompassing Osprey lifetime warranty ensures their dedication to superior design, craftsmanship and quality of their products is backed up by their actions to replace or repair a pack so it lasts a lifetime. Or two.
Here are some details.... Osprey will repair for any reason, free of charge, any damage or defect in their products, whether it was purchased back in 1974, or ordered right now from this site. If they are unable to perform a functional repair on your pack, they will happily replace it. Osprey proudly stands behind the All Mighty Guarantee, so much so that it bears the signature of company founder and head designer, Mike Pfotenhauer.
Some Osprey All Mighty Guarantee FAQs:
What do I do if my Osprey pack needs to be repaired?
If you live in the United States and need a repair done on your Osprey pack, you will first need to obtain a Return Authorization number. You can do this by reaching their Returns Department at 866-314-3130, or using the information that is provided with a new Osprey pack.
What do I do if I just need a replacement pack part like a buckle?
Give Osprey a call at 866-314-3130 and they will take care of you.
How long will it take?
You can tell Osprey you need the pack returned by a certain date when you request a Return Authorization number, and they will do their absolute best to meet that deadline.
What if my pack is super dirty and stinks?
Clean it before you send it to Osprey to get repaired. The real reason is that there is a law that says if your gear is too dirty or odiferous (smelly), Osprey is not allowed to repair it and will just return it to you.
Do I have to pay for shipping?
A little bit. You are responsible for the cost of shipping the pack to Osprey, and they will pay shipping to return the pack via UPS or FedEx. Osprey cannot be held responsible if packages get lost in transit, so make sure you get a tracking number when you ship your pack out. Also, if you use expedited shipping be sure to let Osprey know (866-314-3130). They, in turn, will give your pack priority processing and return it using a similar expedited shipping method.
Do I have to register my pack to take advantage of this incredible guarantee, and/or need to be the original owner of my Osprey pack?
No! Osprey's All Mighty Guarantee is truly ALL MIGHTY. If you own an Osprey pack that needs to be repaired they will repair or replace it.
JUST A HEADS UP: If your Osprey product is not repairable and is replaced, the original product will not be returned to you. They will try really really hard to repair your pack, but if they are unable to make a functional repair, they will replace it. For products that are no longer in production you will be contacted by Osprey to discuss replacement options.
All good answers. So what is NOT covered?
• Osprey program packs or any Osprey pack used by outdoor programs are ONLY covered under Osprey's Program Pack Warranty, NOT AMG.
• Size and/or fit issues. Make sure you buy a pack that fits. Check out the size guide on Osprey product pages for more info.
• Personal preferences like colors you don't like, style of the pack, or not enough/too much room in your pack. Check the product description, features, specifications, and size guide to make sure you are ordering the right pack for you.
• Third party Repairs or replacements. Send your Osprey pack to Osprey and Osprey only to get fixed. Easy as that. And don't try fixing things yourself.
• Cosmetic wear and tear including any reasonable aging of your pack that affects only the appearance and not the function of your pack. Be proud of those scars!
• B.A.M.G. (Before All Mighty Guarantee) Repair Work. The All Mighty Guarantee applies only to repairs requested on or after January 1, 2009.
• A Osprey Hydraulics reservoir is covered by a limited 1-year warranty, which is the reasonable lifespan of a reservoir. Pouring and storing of warm/hot or boiling water in your reservoir WILL VOID your warranty, so don't do that. Reservoirs are NOT designed to contain or handle liquids at temperature.
