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.

Missing piecesNot happy. The product I purchased is missing a critical piece. I purchased the filter in shop far away from my home so I can’t easily return it. I’m just great full I checked the unit before taking on a hike.

Love this system. Easy toLove this system. Easy to use, and easy to clean/back flush. The flowrate is really quick so I have fresh water in no time and the large size makes it so I don't need to re-filter very often. I also love that the filter itself is protected with the foam pads, though they can be removed if you're trying to save space.

Great Remote Aid Station For Trail Races Water Filtering SystemWe have trail running events that take us into remote locations where we either need to hike in water or filter it. We've tried the pump filters and it was faster to carry in the water rather than pump our arms for days on end. Our first experience was great, filtering 10 gallons of water with the 6.0-liter system at an aid station in 25 minutes. We'll be buying more for future use.

Mixed feelingsThe concept of the filter is great. Relatively easy to use and gravity does most of the work. It also is lightweight and easy to store/pack. However, the disappointing part is the dirty bag (which is similar to a zip-lock). No matter what you do, you can't really get it to close! If you do, it will reopen in a few seconds. Having the dirty bag open has two downside, first you get air in the system and second you start losing some of the water. I'm not sure if mine is defective or if this a problem with the design.

Great size for a large groupHi. We used this for 3 hikers to fill up our camel backs. This was super nice to have this volume. However, if I were treating it myself, I'd buy the 4L. It worked very well. Occasionally, I have to raise the dirty water bag much higher to start the cleaning process. I learned that when I noticed the cleaned bag was empty. Preparing to store this away was a bit of a pain after my trip. The cleaning part wasn't the problem. It was the drying of the "CLEAN" water that was dissappointing. I had to let it sit out for a week to ensure all the water dried out of the clean reservoir, because the only access to the inside is through its little 1" diameter fill/drain port. Overall, I was satisfied, I was a bit dissappointed on the drying aspect of the clean reservoir though.

Makes life easier!We already had the 4L but saw the 6L and knew we needed it. We use a ton of water at our campsite and I loved the convenience of having more water and not having to go out in the middle of the lake to get more as often. The water is clean and so much more convenient than a hand pump

Convenience you didnt know you neededWhen in the wilderness, water is used for everything. You realize how important it is when you have to wait for it each time you need it. This is the case with typical gravity filters. With the reservoir system, water is cleaned and waiting for you while you do other things. Hard to realize how great this is until you dont have it.
Hey John, great question! This GravityWorks Filter is model number 11164 from Platypus, I hope this helps!

Approximately how long does it take to filter 6L of water? I realize that particulate size and quantity will affect this but can you give me a ballpark number please?
Asked by: Capt Andy
Hey there, thanks for your question.
The Platypus GravityWorks 6.0L Filter System filters up to 1.75 liters per minute so it takes a bit less than 3.5 minutes for the full 6L reservoir to filter.
I hope this helps!
