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.

Special order items take longer to ship

ThermaCapture
ThermaCapture Radiant Heat Technology is a proprietary reflective coating that we apply to a range of surfaces. By reflecting radiant heat back to your body that is otherwise lost, this extremely lightweight coating turns that surface into a very efficient heat reflector, amplifying warmth without the excess weight or bulk of added, conventional insulating materials.

Extraordinary Quilt - Super LightThis is possibly the best quilt you can buy. It's incredibly lightweight. Pick it up and you'll be amazed. Even in it's storage sack with tags on it in the store it will seem astoundingly light. It also compresses very well, taking up very small space in any pack. Another prominent feature is that the down is Nikwax treated, which is the very best hydrophobic down treatment on the market. The shell is treated as well. Rest assured when heading into a wet, rainy, damp area. This quilt will retain its loft, day after day.
Some keys to know: The shell on this is only 10D nylon, which is thin, so you're going to want to baby it just a little. No zipper to snag though, so that helps. I strongly recommend you use this quilt with a comfortable sleeping pad. I also recommend you use it either with a light sleeping liner, or the Therm-a-Rest pad cover/sheet. While those add extra ounces, they will make your sleeping night much more comfortable than sleeping directly on the nylon of a pad. Finally, in a pinch you can bundle up in this and wrap it mostly around you, unless you're a very big person, which is a concern some people have.
The Vesper also comes in a 32 degree version, but I always tell people when in doubt just buy the warmer of the two choices. Unless you know you won't ever use it near freezing, and weight is absolutely critical, this is the quilt to buy. Finally, if you love the features of this, but decide you want an actual sleeping bag, look at the Therm-a-Rest Parsec and Hyperion. Both have many of the same qualities of the Vesper, just in sleeping bag form.

Light and warmOnly used this on one trip so far. Love the lightweight and packability. Short backpacking trip with lows in the high 40s. First night I slept in a tank top and was a little chilly after a few hours. Second night I added socks and long sleeves to sleep in and attached the quilt under my sleeping pad, and also used the baffle snap, and was fine and cozy - I think most of the issues with feeling chilly on the first night were from not having anchored the quilt under the sleeping pad in combination with underdressing. So far, a winner. I don’t do a lot of winter camping, so can’t say how this performs in lower temps. My primary reason for purchasing was to reduce pack weight and still be warm while camping. I’m pretty happy so far.

ConvertedMy new quilt saw its first use in Mt. Rainier national park on a four day backpacking trip, and I am a new convert! VERY lightweight and packable for 20°F protection. Definitely kept me warm enough and was versatile when paired with my sleeping pad.
I’m not sure that a quilt is perfect for EVERY condition, but I will be using this product a lot more and am very excited to have it as part of my sleep system.

Very happy with this bagI bought this bag a couple of years ago, since I mostly sleep on my stomach. It was my first quilt, and I really enjoy it. Just by getting a leg or arm out you can regulate your temperature very well and take it into warmer temps then what you could with a sleeping bag with the same rating.
Because it packs so small it is easy to bring on adventures when traveling with a smaller backpack.
I splitboard a lot, and I take this bag snow camping most of the time.
Up to freezing this bag does great as a solo bag, when it gets further below freezing I pair it with a summer bag.
The price is quite steep and the new Ohm bag seems like a good option as well. But I would still recommend this one and I'm happy with my purchase.

Best addition to my sleep systemWow, I didn't think I'd ever need something like this quilt, but it has saved me a number of times - both in hot and cold weather! It has served as a critical extra layer when the temperature drops, but I have been using this quilt more and more as my MAIN layer instead of any bag when the weather gets warmer with nights in the 50s. I still can't believe how they fit this thing into such a small package. The SynergyLink Connectors are an awesome addition - being a tall guy that constantly tosses and turns at night, these connectors have made my nights in the backcountry much more comfortable since I actually stay on the pad!

Look no further, this isLook no further, this is the quilt. Warm, great fit and functionality. I’m 5’10” for reference, plenty of room to spare. The loft is amazing and the treated down is good for the single wall tipis with the morning dew. You won’t regret it.

Love it!The Vesper is exactly what I was looking for and exactly as advertised. Amazing, packable and warm quilt-like option. Highly recommend
What type of sleeping pad is recommended?
When I do multi day thru hikes I bring my inflatable Nemo short 8 oz pad. Not sure the shorty would work too well
Asked by: Daleen
Hi Daleen, thanks for the question! I honestly don't think your Nemo pad would cause any problems with this quilt, you can see a standard pad strapped to this quilt in that second to last stock photo. Just keep in mind this Long we have available is 79", I hope this helps!
