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.
"Get it by" - For in-stock and ready to ship items, choose the your shipping speed at checkout to get your items by the "get it by" date. Your items will ship SAME DAY for orders placed before 3pm EST.
"Oversized" - This means the item is large and can only be shipped using 4-6 Day ship speed. Additional shipping charges may apply.
"Freight" - This means the item is too large for standard shipping methods, and must be shipped by truck freight for an additional fee. Someone must be present to inspect, sign, and accept delivery, so we will call you to schedule delivery.
If you have any questions, please Live Chat or call us at 877-666-7352.
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.

Absolutely Perfect Bag for Day Hikes + Hydration[This review was collected as part of a promotion.] I did receive this pack as a #giftedproduct, but that in no way influences my review or remarks. I have been a huge fan of Gregory for years. I use their bags for backpacking, day hikes, and commuting. Their bags are top-notch quality, feature-rich and comfortable. The Inertia 18 is no exception.
Why do I love it? The small footprint gives way to a massive amount of capacity without feeling too bulgy. The bag itself has a shape that it doesn't lose when empty - making it easy to pack up, sort through, and clean up. It's got all the bells and whistles that can be jammed into a small package: Amply sized main storage compartment, a separate hydration pocket, a front knickknack pocket at the top, a mesh water bottle side pocket, and a bonus zip pocket on the other side.
The back panel mesh on the back allows pretty good airflow, and the straps are nice and lightweight so they don't feel too bulky or heavy - even when the sweat hits.
But the gem: The hydration system. Gregory absolutely killed the game with their hydration systems - hands-down best on the market. This bag comes with a 2L bladder which is the perfect size for most hikes that I do. On hot days, I will throw an iced-down water bottle in the side pocket. (I Live in AZ). The bladder has a quick release system meaning you can completely pull it out to fill it up. So easy and clean. It has a wide mouth to make filling simple. There is a handle to help carry the bladder outside of the bag. The lid twists on and off with ease and is very secure - which is where many other brands go amiss. The INertia's hydration compartment has a built-in hook to hang the bag from so it doesn't slump around, and because of the hardened back panel of the bladder, it stays in place - and keeps that water upright and ready to flow.
It's also the simplest water hydration system to clean. Gregory integrated a hook for you to be able to hang the bladder upside down. I usually throw a paper towel or small towel in the bottom to soak up any water, making sure to keep the mouth open for airflow while the bladder dries itself out.

Size Guide
Gregory Men's Packs
Gregory backpacking packs are available in a size range. Please check the PRODUCT FEATURES and / or SPECIFICATIONS for the torso range measurements of each size of a pack. The steps below are a guide for measuring your torso size.
The hipbelts on Gregory backpacking packs are adjustable to fit a range of sizes. A simple rule of thumb is that the ideal distance between the ends of the hipbelt pads after tightening should be 3 to 5 inches. However, the most important criteria are that the hipbelt wraps clear over the side of your body and that it rests 1 inch above your iliac crest. This allows proper load transfer to your skeletal structure, which maximizes comfort and minimizes energy expenditure.
HOW to MEASURE TORSO SIZE 1. Put your chin to your chest and feel for the big bone protruding on your neck at the top of your spine. That's the C7 vertebra.
2. Feel your hip bone, the top part of this is your iliac crest. Find the spot on your back that is level with the top of this crest.
3. Have someone measure the distance between these two points, following the contours of your spine.
