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 GRAB20 to take the 20% off a 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.

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.

Size runs smalls and made for wide shoulders(This review was collected as part of a promotion.) I’m 115lbs 5.3” petite frame. I purchased a size small and it fits tight. It’s a poor fit for narrow shoulders as the ‘sleeves’ fall off my shoulders. Excellent quality but thin - your bra will clearly show through.

Bonne qualité mais transparente(This review was collected as part of a promotion.) On voit vraiment tout au travers, j’ai du la retourner. Mais la qualité est vraiment bonne, j’adore ces camisoles pour m’entraîner, aller courir en montagne et même pour aller travailler.

My Winter Wear Everywhere WareVery comfortable wool, the wider straps hide bra straps when you'd like to wear it without layering, and somehow it makes you look fabulous!

A tank to live in, 4 seasonsI purchased my first Siren Tank for an 800 mile thru-hike and it did not disappoint! I wore it non-stop, removing it only for an occasional washing. I slept in it, hiked in it, swam in it, wore it through snowstorms and 95 degree days at the bottom of the Grand Canyon....
Perfect for any season, it's an ideal 4 season underwear item - and works well for my body type (tall, slender and small breasted) I now own three of these!! Colors are fun, and it's a particularly great deal if you can buy it on sale!! Oh, and it's so well made, after 2 years of frequent use, it's still in perfect contrition.

Keeping me warm for winter[This review was collected as part of a promotion.] I'm using this as a base layer to keep me warm during the Central Otago winter - it's perfect to wear under shirts etc.
