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.

Warm & comfortable, bulkyAfter a lot of research into a good winter/backpacking sleeping bag, I opted for this one. Definitely wasn't expecting the size when it was delivered, I got the long being 6'4 and this things huge. Takes up a good chunk of my 70L pack. Tested it out recently in backcountry Kananaskis, temps dropped to around -8, paired with a sleeping pad/mat (R Value 5.2) and wearing base layers, I woke up too hot and had to unzip it for half hour. Overall I really like this bag. I was on the fence about the size and almost returned it but after looking at all the other options, unless you're willing to spend 6/700 bucks, then this is the bag for you. Best I could get the bag in the stuffsack was 12 x 17" - the stuffsack is super cheap quality and split right down the middle of the material (not on a seam) when I was packing up in the morning - the reason I give this 4 stars.

Big but warm, cheap stuffsackI bought this bag after researching sleeping bags rated for backcountry winter camping in Alberta. The weight is not ideal for backpacking but at this price definitely not a deal breaker for me. However, I was not prepared for the size of the bag when in the stuff sack, best I could get it was 11 x 17" which meant it filled close to half the volume of my 70L pack, definitely not ideal and I almost returned it. I'm glad I didn't however. Just got back from a trip, -8, sleeping pad/mat combo (R value 5.2), the usual base layers and I had to unzip the bag for a few hours early morning, was too warm. Very happy with the performance. Went to pack the bag away prior to hiking out the next morning and the stuff sack split right down the middle of the material, not even on a seam, super annoying and ended up just having to stuff the bag in the bottom of my pack. Would have given this 5 stars had the stuff sack lasted for more than one trip. If only they put the same effort into the stuff sack as they do the sleeping bag they'd have a winner. Now I have to go buy an additional stuff sack, thanks Therm-a-Rest.

Only flaw is sizeThe only flaw I can possible find with this bag is it's packed size, not weight but the volume of this bag actually forced me to upgrade my backpack to accomidate it's size however every other thing about this bag is perfect

FlawlessI took this bag on a mountain goat hunt in northern BC and it worked great. It’s nice to know after a hard day that you can sleep in warmth and comfort

Staying warm and dry!!Found my 32* Saros a little chilly getting into the winter rafting months and upgraded to the 0*. A bit bulky to pack but 100% worth it to stay warm on the river this winter.

Great sleeping bag for the price.Bought about a month ago..used at 45 degrees fahrenheit with no issues, never had to zip it up at those temperatures . I'm confident it will perform at 15-20 degrees with no problems provided it's used in conjunction with a high r rated pad ...was able to side sleep with ease and did not feel as constricted as I have with most mummy type bags.
