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.

The Western Mountaineering SummerLite 32 Degree Sleeping Bag is a backpacking sleeping bag for lightweight summer adventures. When dropping weight is important and the nighttime lows don't drop too far, look no further than the SummerLite. It's not just the 1lb 3oz that makes it amazing, it's also fully baffled with draft protection at the zipper, so when the temps drop down to 32 degrees, you can snuggle in and won't get any drafts. Lofty as can be and still packable into a 6"x12" stuff sack, so it won't take up the whole of your backpack. Gotta love those summertime hikes, where you can pack less and cover plenty of trail.

Awesome purchasebought this about two months ago for summer backpacking and am extremely pleased.
quality is extremely high, temp rating seems very accurate, packs to size of a nalgene and it's ~ 1lb. very comfortable / cozy bag for the weight.
its not inexpensive - but you definitely get what you pay for. WM bags are top notch, this is my 2nd and i've had the 1st one (versalite, 2 lb 15 deg) over 12 years and taken it everywhere - this one is lighter, smaller and more suitable for summer here - only reason i bought it.

5’11” 205lbs with a puffy jacketArm space is a little tight, but I still felt comfortable and had *just* enough room to shift positions throughout the night as a 5’11” 205lbs guy wearing a nano puff jacket. I was at ~ 7,500’ on a 30° night with a mild breeze and intermittent rain/sleet sleeping on packed snow, inside a custom Borah bivy, on top of a ThermaRest NeoAir Xtherm, and under an HMG dyneema tarp. I’m a moderate/cool sleeper with colder feet, but the only loss of heat I noticed was from the thin baffle covering the zipper near my thighs. Bottom line: great bag, even for a bigger guy like me.

Still love it, 4 years laterBought this (here) four years ago. Used it down to about 32 degrees, and I was comfy with my baselayers, warm socks, and an ultralight down jacket. My feet get slightly cold in here, but not enough to keep me awake. For the weight, this thing is incredible. Roomy enough for me to side sleep (5'10", 145). The zipper is pretty good, occasionally gets stuck on the draft tube, but that seems expected. I worked overtime to get this bag, and it was worth every minute. The hood cinches down nicely and holds in so much heat vs leaving it open.

Best cocoon everI bought this for my best friend recently, after having a western mountaineering sleeping bag myself for the past 4 years. I'm glad to report that he has already slept in it numerous times on the trail and at home, much to his wife's dismay. These are the coziest most comfy sleeping bags money can buy. Your life will be changed upon buying and sleeping in this new bag. Made in America and even came with a sweet signed card of the nice people who did the sewing on the bag.

Good for High-altitude Thru-hikingI recently used this bag for a thru-hike of the Colorado Trail (490 miles, avg elevation of 10,300' msl), and it performed flawlessly for what it is. For a one-pound mummy bag it was very packable, light, and decently warm. The finish workmanship are flawless. I say "decently warm" because although this is stated as a 32-degree bag, even with a Patagonia R1 hoody, tights, and socks, most night I was cold by about 3-4 in the morning. Those nights ranged between 25-35 degrees F, so I would say this is closer to a 40-degree bag. But, everyone is a bit different so keep that in-mind. For what it is, it is outstanding but if you're gonna be in sub-32 degree nights, I would suggest layers and/or a liner. The outer shell is light, as expected, so be gently with it, as expected with any ultra-light gear.

Awesome bag! A bit too snug for me.I wanted to love this bag, it's a great bag, but after 3 nights in the sawtooth mountains (mid July) I knew I had to look for something different. The bag itself was incredible. Ultra light, sleek, simplistic design but it just was too small. I am a fairly built guy and just needed a bit more space. My shoulders are broad enough that it would compress the down and I'd get cold spots.
I'm a warm sleeper buy first two nights of my trip (again mid July in Idaho) I didn't put the fly on my tent, the temperature dipped into the lower 40's upper 30's and I got cold. The last night I put the fly on the tent and the temperature only dropped into the 40's and I stayed toasty warm.
This bag has no neck baffle and the draw string to close your head box is off center and felt a little awkward to me. That being said it may not bother someone else at all.
If you're lean and don't move much at night, this might be the perfect summer bag, but if your broad and like to have a little more wiggle room this may not be what you're looking for.

Great quality but not sure about the 32F ratingI first used this bag in July in the Pecos Wilderness. Low temps were around 40F and I had to put on all my clothes to stay warm enough to sleep. But the bag is very high quality, plenty of room, zipper works great, and hood is well-designed.

One of the lightest!I love this sleeping bag! So much I wish it it had holes for my feet and arm so I could walk around like a mummy in it lol. Now being more serious, it's warm and comfortable. Packs down nicely. Full length double zipper perfect when needing to cool toasty toes. Also I'm 6ft on the nose. A regular bag works perfectly. If I were two inches taller I'd want the longer one.
I'm looking for a bag that can compress really small, how small can this one get to?
Asked by: blue
Hiya blue, thanks for your question! I personally have this bag (love it!). It compresses pretty darn well. The stuff sack measures 6 inches by 12 inches. Hope this helps!

Is the stuff sack water proof?
Asked by: kathi

I am 182 cm tall, 70 kg, which one should I choose? Regular or Long?
Asked by: Syan
Hey there, thanks for your question.
It looks like the long would be a better fit for you.
