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.
For Moosejaw Rewards members only. New members enroll for free during checkout.
You must use code CLIMBERS20 to take the 20% off one full-priced item.
The deal is only on in stock items. Deal cannot be applied to prior purchases or with other promotions.
Load bearing climbing equipment, like a harness or carabiner, is final sale by law so if you don't like your climbing stuff just hang it on your wall to impress your friends - sorry for being so mean about it.
The code is only good through February 19th, 2023.
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.
The Western Mountaineering Puma MF Sleeping Bag is a lofty, cold weather sleeping bag for spending nights in the high mountains during winter. Rated to -25°F, the 9" loft wraps you in 850+ fill power down. Forget about the howling winds and blowing snow as you tuck into your tent and sleeping bag for some shut eye before pushing the summit in the wee hours of the next day. The two draft tubes intersect, each packed full with plenty of down to seal out drafts along the zipper and collar. The MicroLite XP™ shell provides the water resistance you need against any snow, rain or condensation that may find its way into the tent.

12 years with this bag!As a hitch hiker, wedding photographer, and landscape photographer, this bag has taken me all over the US and never has left me cold. I’ve pushed many negative temps with this tent, in and out of a tent, and I’ve never been left wet or cold. Doubled up with some light layers and you’re ready for the apocalypse practically.

Superior loft in a shorter packageWhat o love about this bag is that it’s short (I’m 5’6” and so is the bag) BUT it’s wide enough for extra layers or to throw electronics or a hot water bottle inside. It’s still lofty and lightweight though. I haven’t put it to the limit though it’s kept me warm below zero. I’d say the construction and fabric is tougher than my other bags from FF and montbell

excellent bagThis has been my late October Elk camp bag for the last 6 years. We spend the week at 10,000. While we never know the temp other than real cold and cold my partner in his 25 below synthetic bag regularly is cold and restless in multiple layers, while I sleep in just a base layer or less with no problem other than getting too hot. Ground cover is obviously important but for the job the bag does it's worth the bulk. I used to freeze my a@# off and finally pulled the trigger on the bag and I have been warm and cozy since.

Not very packableI had extremely high expections for this bag. My main reasons for purchasing this were for warmth and packability. While the loft looked amazing, trying to get it into a 9x18 stuff sack was a nightmare and then it wasn't very compressible. While this may be a very warm sleeping bag, I also needed it to fit in my 70L backpack.

warm, light and it fits in my superlight osprey exos 34 backpack along with all my other gearI bought the Western Mountaineering Puma MF Sleeping Bag because I am always cold. I was looking for the warmest light bag on the market. After a lot of research I found out that the Puma MF was the lightest -25 degree bag. My only concern was fitting it in my backpack along with the rest of my gear. Amazingly, a large compression sack helps me fit it in my superlight osprey exos 34 backpack along with my NeoAir sleeping pad, dawn pants and jacket, a few extra layers of clothes, crampons, food, and everything else I need for a backpacking trip. I spent the night in the crater of Rainier in my Puma sleeping bag and I was worm. I consider it my best buy. It is worth the money.

Loved itSlept in this at 14,900 feet in Nepal. Everyone else froze in their bags--I was toasty warm.
Being exactly 5'6" would i get a 6ft? Or exact size? Is there enough room for a nalgene bottle or booties in the 5'6" bag?

Asked by: Kerisa
Hey Kerisa, thanks for the question! It kind of depends on the type of sleeper you are, stretched out or curled up. Generally though, if you are right on the edge I would most likely recommend going up, especially if you may want to be wearing booties. I hope this helps!

How well will this work for side sleepers? Should I go a size larger (I'm 5'11" and could go with the 6'6" bag)?
Asked by: Peter
Thanks for the question! You never want to go larger in a sleeping bag unless you absolutely have to. You do not want that much space in between your feet and the bottom of the bag because heat will escape. It really comes down to the mattress. As long as it isn't too thick, you should have no problems sleeping on your side. I hope this information helps!
