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. 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.
The Western Mountaineering Ponderosa MF 15 Degree Sleeping Bag is a versatile sleeping bag rated for nights down to 15°F. This is not a steakhouse. But if you're feeling hungry I'm sure you could still eat while sitting inside it, after all there isn't a hood attached that will get in your way. The 2lb, 9oz bag has been packed with 850+ fill power down for a 7" loft. Talk about toasty warm, plus, it's plenty spacious for larger folks or those that have a problem with small spaces. Heck, you can even unzip it past the footbox and sleep out blanket style. Or zip it together with another bag for co-sleeping with your favorite hiking partner.

If you are big, this is a great bag!I start the review at I did, because as a big man, I have never had a packable bag that was comfortable. Soldier straight no room to turn body, let alone shoulders. This is the perfect bag, the name Western Mountaineering in the quality and support behind the bag. FYI - 6-1, 270 lbs, broad shoulder

Best bag ever!!!it took me 40 years to find the best sleeping bag ever! Oh, the loft!!! I have had many bags in my lifetime and camp all over the damp PNW, even in summer there is a chilly moisture in the air, especially at the beaches, not an issue in this bag. I am warm, dry and extremely comfortable all night long. I can toss and turn or flip to my stomach easily. Gone are the days of needing to steal my husbands top of the line marmot, he will be getting one of these soon also!! Highly recommend to anyone looking for the investment of comfort and warmth! Side sleepers and stomach sleepers must have!!

Best $$ spent on a sleeping bagI just finished a 2 week backpacking/hunting trip in the San Juan mountains in CO. This bag kept me warm through a few wet, rainy, and snowy nights( I slept under a tarp so I was exposed to some of the weather and wind ) and was super toasty the rest of the trip in mid 30° nights. I'm also slightly claustrophobic in mummy bags and this sleeping bag gave me plenty of room to move. I was hesitant to spend so much money on a sleeping bag but it was worth it.

Warm and ComfortableWith a recent move to California, and hiking a lot in the Sierras, I decided I needed a nice 15 degree bag, but didn't want a mummy style as I'm a big guy and those make me feel too tight.,,,,I was recommended the Ponderosa and went with it. Excellent move. While I haven't camped in anything below 30 degrees yet, I have yet to zip the bag up entirely as it keeps me so warm (I am usually hot to begin with, so that might not be the case with you).,,,,The bag is comfortable, and I love the ability to have my feet in the pocket, while having the entire bag unzipped.,,,,Have used this in Yosemite National Park, Yellowstone National Park, Sequoia National Park, Courtright Reservoir and many others. Great bag.

HIGH QUALITY, MULTI-PURPOSE 850 fill bagWestern Mountaineering's Ponderosa MF is square cut. Unzipped it becomes a toasty comforter for 2 of far better quality than those heavyweight overpriced comforters with high feather content. My favorite feature is the stiff fabric alongside the zippers. This prevents snagging even when your fingers aren't freezing. I'm baffled. Why doesn't such a fine bag include a stuffsack and a storage bag? I prefer this bag to my Moonstone PCT!...TIM

worth the moneyextremly warm sleeping bag.
Hello. I am intersted in the Poderosa MF. I am 6´1" and am wondering if the 6 foot model is long enough. what is the interior length since there is no hood? Ted
Asked by: Teddy
Hiya Teddy, thanks for your question! You could technically use the regular version, however, if it gets cold and you want to pull the draw string at the top to duck down into the bag and keep warm, you won't have enough room.
I reached out to Western Mountaineering regarding this question and they highly recommend that you get the long version.
The regular measures approximately 76 inches, which sounds roomy for a 6 foot bag, but it's really not when you get into it and get settled. The long measures approximately 82 inches. Hope this helps!
