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.

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.

Worth the investment[This review was collected as part of a promotion.] Slept on uneven mix of snow and rocks. The pad made it all feel the same and I couldn't tell the difference! Comfortable and warm. You can sleep on your side, although it isn't as comfortable as a regular mattress. I'll be taking it on a 3 week backpacking trip. For all those nights of sleep, I consider this to be worth the price. Packs down well and easy to setup. I'm 6'4 and got the long pad. My feet didn't overhang the pad.

Winter camping[This review was collected as part of a promotion.] These mats work awesome! We slept outdoors for 3 nights in northern Maine (in -3 temps) and we were warm and dry!! I definitely recommend them!

Good padThis pad is probably the most comfortable I've had. I'm a back and side sleeper and it was great. The extra insulation was also good at keeping me isolated from the cold floor. My only gripe is the reference to being called extreme. I recently did a pretty tough outdoor excursion and this pad was completely shredded or punctured. If you are using inside of a tent, I would argue it's the best. If you want to use it in austere environment and hiking through brush, you might want to steer away. In my opinion, if it's called extreme then it should survive harsh terrain.

First trip with this pad[This review was collected as part of a promotion.] First trip with this pad was an 8 day elk hunt with temps frequently in the low 20’s at night. Used the pad directly on the ground in a tarp tent as well as a couple nights in a hammock. Pad was comfortable and the insulation was great, I never got cold.

Warm but noisyIf warmth is your critical factor this pad works great. It also is contoured and works well with other sleep systems like Zenbivy sheets. My biggest complaint is how noisy this pad is. It's literally the squeakiest of all the various pads I've owned. I even later bought a bag liner to put over the pad to reduce friction with the tent bottom and sleeping bag bottom but it didn't help much. It sounds like one of those cheap styrofoam egg cartons all night long. But it is warm and keeps you off the ground high enough to not feel rocks and roots. I think if the surface was flat rather than dimpled, it would be much quieter when pressure is applied.

Great pad. Slept on it[This review was collected as part of a promotion.] Great pad. Slept on it in cold temps at elevation - near freezing right out of the gate- was super warm and the integrated inflating system built into the stuff sack was so easy to use. Warmer than I thought it would be.

Fantastically comfortable but miserable to pack upI knew the instant I opened the brand-new package that it would be a nightmare to pack up after using it. It is a common problem I've encountered over the years with tents and sleeping bags and such by many manufacturers. You get them and even coming from the factory after being vacuum compressed the thing barely fits in its carry bag. Rolling it back up to factory level tightness is extremely difficult in the field yet so many companies, including Sea to Summit, it seems, can't be bothered to provide even a little bit of extra room in the stuff sack to give you some margin for error.
I had to re-roll it three times in my living room being extremely careful to maximize perfection when I first got it. This is an absolute NIGHTMARE in the field. Especially for a pad like this that is designed for extreme cold. The last thing I want to have to deal with is trying to perfectly roll a pad at -30 degrees with my bare hands... I will likely have to find another carrying bag for it for true cold camping this winter. (which will be annoying because the carry bag is also the inflation bag)
This is something I love about my therm-o-rest. It has extra space, and packing it up is trivial and easy because the bag is 10% bigger than it needs to be.
That said, other than the infuriatingly small carry case this is a fantastic sleeping pad. Easily the best I've ever used. Far more comfortable than any Therm-o-rest that I've used. This is the closest pad I've ever had to feeling like a real bed. I haven't tested it in extreme conditions yet to see how true the R of 6.3 is but so far VERY HAPPY with the pad itself.
5 stars for the pad, 1 star for the carry bag. Averages out to 3. ;)

Even at 1/3 full it’s still comfy.A while back I purchased this pad for my partner (5’11”, 200lbs). He’s a princess side sleeper and getting him to go backpacking required a proper sleeping pad. When he wasn’t using it I used it…. So naturally I needed my own (seriously it’s comfy). I have one dog who I always backpack with and have never had an issue with her ruining sleeping pads, my other dog however got to go on his first overnight trip and sliced my brand new pad open….. Thankfully we had 2 repair kits on us and I tried my hardest to patch the thing. But the instructions don’t account for being in the middle of nowhere on the Superior Shoreline so it wasn’t pretty. However I got it to hold some air. I was 100% pouting about this, but after settling into the tent for the night was able to honestly say this pad was amazingly comfortable at 1/3 full….. and I was able to fix the pad for me after getting home (5’4”, 120lbs).
