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.

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.

Excellent with caveatsI bought these to use over my trail runners and approach shoes. They are light, comfortable and keep things out of my shoes very nicely on trips where a full gaiter is too much. I do like them, but have had some challenges and issues. Tips: first, remember to put the gaiter on before your shoes! I find it helpful to unhook one side of the foot strap, then hook the foot strap on fully over the shoe. Otherwise you risk popping the foot strap if you try to just slide it over the shoe without unhooking. Secondly, the lace hook doesn't work well with all my laces. Flat shoelaces like my Altras, or speed laces like my Salomons they work fine, the round laces like on my La Sportiva approach shoes (Tx3/Tx4) it is very difficult to get the hook on and off the shoelace. On a more rugged trip I took a tumble, tearing the foot strap off. I didn't notice until a little further along and wasn't able to find it. This also pulled the elastic cording out of the stitching and the lace hook was gone. I was able to very easily re-route the elastic back in and stitch it. I reinforced the stitching on the other gaiter, assuming it would also tear out. I bought new foot straps, but unfortunately OR does *not* make the lace hook available for purchase or to mail out as a warranty item. That's frustrating, as I had to make my own lace loop out of some velcro. A less crafty person would just be out the gaiters at this point.

Elastic bands break easily...But they stay up!I really like these. Now that the trails abound with greenery, I have found I don't really like some of the overgrowth to touch my legs. I was excited to try out my new Ferrosi Thru Gaiters. But, just like my previous pair, the elastic cord that holds the band under the shoe broke on one side the first time I tried to put them on. But, since I wasn't trying to keep anything out this trip, I pressed on. I have big girl calves so I wasn't sure these would stay up. They did!! The one that worked, worked great. And the one that broke served it's purpose for the day. If I can get a pair that the elastic won't break, these would be awesome.

Love these Gaitors!I am so ready to hit the trails with these mid-gaitors. I wear a 9.5 women's and have had trouble finding the right size for my shoes. Most small/medium are too small and this one actually is a bit big for my running shoes, but will work great for my hikers. I may just have to get a pair of low-style for my running shoes. These are so light and pack up great. I can't wait to use them!

Great but don't lastI love them but after only one season and 17 4ks (a few backpacking trips) they are already much more worn out than I would hope. There is a hole in one of them. They also fit on the smaller side. I will probably buy another pair for the upcoming spring/summer/fall hiking season, however.

Great valueLight weight and easy to use. Great value for cold weather hikes or dusty trails. Very cold here in Washington right now ( March ).
I will be using these on the PCT section hike this weekend. Totally expect snow on the trail heading north. A most have gear to keep the moisture out of your boots.

Ferrosi Thru GaitersI was excited to be replacing my previous OR light weight summer gaiters and I wanted to love these, but I had to return them. The new placement hooks don't work easily with my boot laces or even with its own lace. I spent a long time trying to get the hooks over my laces-being plastic hooks they can not be pried open a bit more, and it was even difficult to hook onto its own side elastic. The drawstring at the top of the ankles left the fit baggy & floppy. It took 20 minutes to get my gaiters off my boots. Imagine a water crossing with taking these in & off? I will continue to use my traditional heavier weight OR gaiters since it's getting cold and will look for products changes hopefully before next summer.

Great lightweight gaiterWorks as advertised and really lightweight. Two minor issues are reason for only 4 stars. First, you have to put them on before your shoes as they can't slide over. And second, the hook clasp that connects the front to the laces is hard to get unhooked when you take them off. I've used on both the La Sportiva Ultra Raptor trail runner and the La Sportiva TX4 approach both of which have thick round laces. Even with these minor inconveniences they still work great keeping water, rocks and other debris out of your shoes when off trail or scrambling on scree.
