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.

Thanks to easy-to-use trad buckles, getting in and out of the harness as well as adjusting is super simple and fast. When it comes to racking, you've got seven gear loops to choose from, which are also color coded for ease. Now that's what I'm talking about. Time for some vertical action.

I like this harnessSo far I have only used this for about two months in the gym. So far so great. It fits well and is very comfortable. Some critiques I read about this is that it's hard to get the waist belt adjusted tight and difficult to double back the straps. Yes, despite the online description not saying anything about doubling back the straps, the instructions with the harness say to do so. Despite these two critiques I gambled and bought the harness and so far I am glad I did. Yes, tightening up the waist strap takes some getting used to but is not a big issue in my mind. Doubling back the straps is easy if you just pull back on the buckle a bit to 'open' it up. I am excited to take this outside to the crag!

Very comfortable harnessThe Black Diamond Big Gun harness is an excellent choice for outdoor, or indoor climbing. Very comfortable as I am able to sit all day on it with no issues, and the 2 belay loops is a nice feature!

Comfortable as describedThe harness is extremely comfortable and the gear loops are many! I love that there are 7 plastic coated gear loops. I prefer these loops because they don't flop around or sag under the gear weight and are easier to clip the gear onto as a follow. The downside is that they are small gear loops and lay stiffly and close to the harness.
The other downside to this harness is that it's not doubleback buckles. This means putting it on and taking it off is a bit more cumbersome, feeding the strap through, tightening it, and doubling back the strap to lock it in at the waist.
Overall, I am very pleased with the harness. it's great for a hanging belay and all-day multi-pitch climbs!

Very versatileI bought this a few weeks ago and I have been it has been nothing but amazing. I haven’t completely finished testing it but I am very happy with the results so far. The belt has a very wide adjustment range to get over thicker pants for when it’s cold. Plenty of gear loops for as much gear as you could possibly need.

almost greatpros: love the hard gear loops, makes it simple to clip and organize gear. very comfortable on rappel, seems very well made. color scheme is unique.
cons: the belay loop and hard points are very stiff making it sometimes awkward to climb in. the old school double back buckles for legs and waist are a nightmare. i can never get it tight enough to hold up a double rack. it’s constantly slipping down like a dirty diaper. the leg loops don’t stay in place if you’re trying to get a high foot then stand up. no modern buckle kills this thing.

Great multi-pitch harness but can be between sizesThis harness is action packed and super comfortable. I've taken it up over 100 pitches at this point. With the wear of the harness and putting a full rack on it it does get heavy and I noticed I couldn't tighten it enough. So I bought a second harness again in the smaller size in hopes that I would be able to not feel like it was falling off when a full rack is on it. The smaller size doesn't fit, and unfortunately moosejaw doesn't do returns so now I'm stuck with a smaller harness that barely fits my body and a medium harness that feels like it's falling off with a full rack on it. It's a bit of a bummer because I'd give it five stars and this company the same if it weren't for this situation. BD needs to update the sizes b/c I'm sure there are more people in the in-between S & M and M and L categories that are using a big wall harness. Also MJ needs to update their return policy b/c there is no way to try this harness on otherwise

Comfortable, but not super comfortable.I bought this harness for photographing climbing on fixed ropes. I've spent up to 2 hours in this thing, and I'd say after about 20 minutes my legs start to feel it. I tend to get some relief by getting on the wall every 10 minutes to get the blood moving more freely to my legs. I'm using this is a very hot climate, so I'm in shorts, but I imagine if you were using this in an alpine scenario, it could be more comfortable with more layers underneath.
The gear loops could use a bit more space. The upper loops don't come off the harness very far and it makes it hard to rack gear quickly.
I really wish it had an auto lock (doubled back) waist strap. It's the old style that requires manual doubling back to close the system. Ill probably end up painting half the buckle red as a reminder.
All that aside, it's doing it's job well enough, and I'm happy enough with it that I'll continue to use it.
If you just want a comfortable harness to climb in? Maybe single pitch, or a few pitches? This is pretty great. Not too heavy considering the size.

What hanging belay?My legs kept going numb on hanging belays in my Sama, so I went straight to the limit of harness comfort without getting a belay seat. Man. What a treat this thing is. The gear loops are staggered and plentiful. The long loop across the back is a great repository for emergency and seldom used gear that leaves the more accessible loops clear. Not as sweaty as I thought it would be thanks to the pillow padding, but you're definitely going to feel the heat of more coverage. Haven't personally had any cause to use the double belay loop, so I just stacked them together to keep the tie in points clear. Does make smaller carabiners a bit finicky to load, but well worth the comfort and carriage.
