    REI Members get back an estimated 10% on this item as part of their annual member refund.

    The REI Member Dividend

    The REI dividend is a unique benefit of membership in the REI co-op. It's comprised of your member refund—typically 10% back on eligible purchases—and/or your REI Visa® card rebates.

    Each March, active REI members and REI Visa cardholders who earned a rebate receive a refund in the form of an annual dividend notice.

    Only active members receive annual dividend notices. To maintain your active status as an REI member, you need to make net merchandise or shipping purchases of at least $10 per year, unless you joined that year. Member numbers are issued in one name and only that person receives the member refund. Your number can be used by others in your family, but it cannot be transferred to someone else.

    Sea to Summit X-Mug is rated 3.1667 out of 5 by 6.
    Rated 1 out of 5 by from Great idea, poorly executed This is a great idea for a lightweight cup for hiking and camping. Unfortunately, it has a fatal flaw. Pros: It is lightweight and collapses flat. It is not only easy to pack, but its diameter makes it perfect to fit into many pots of the 850ml to 1 liter size. It can handle boiling water and even be boiled or steamed itself. The internal measurement markings are helpful (if a bit too obscure). The nylon rim ring makes it easy to hold even with hot drinks in it and gives it a good shape. Cons: It has one fatal flaw - it retains the smell of food you put in it, which then contaminates every thing else you put into it. The odor lingers forever. I have had two of these: the first was used for tea and coffee with camping. After a winter of storage, it picked up a horrible odor from the pot it was stored in. I had to discard it, thinking was just an anomaly. The new one I got then immediately picked up the odor of its first hot meal of shrimp ramen. Nothing has gotten rid of this smell: dishwashing, handwashing, boiling, lemon & vinegar cleaning, baking soda, nothing. Bottom Line: Despite its many wonderful features, it fails the fundamental test of any kitchen equipment: it makes things taste worse. I sincerely hope Sea to Summit solves this serious odor problem with the silicon body of the cup, which is othewise well designed. But until then the only thing it is useful for is drinking water from.

    Rated 2 out of 5 by from Leaky Cup This cup was applealing to me because it is lightweight and compact. After using it on only a few trips it started leaking. I think it may be a wise choice to invest in something a little more solid.

    Rated 4 out of 5 by from Lightweight and compact but... I used this during a winter climb in the Sierra Nevada mountains last year. I purchased this product because it was compact and lightweight. During the climb, we were caught in some pretty nasty weather and had to dig in. My group squeezed into the larger tent to cook and hang out and wait out the storm and this is when I realized I had not made the best choice. The plastic is so thin it was uncomfortable to hold and yet I could not set the collapsable bowl down for fear of spilling in the tent. I found it difficult to clean as well. I would say this is a decent product unless you are confined to a tent as I was. The risk of spill is too great and in tight quarters and near below zero temps, a spill would not have been cool. Despite bulk, I will use a mug with a lid for all future alpine climbing.

    Rated 5 out of 5 by from Unique concept. Well executed. This product packs small, is lightweight, and works well for hot beverages like coffee. The material allows for easy washing and seems suprisingly durable.

    Rated 2 out of 5 by from Great for the dogs - not for me I got the cup and the bowl for backpacking. While they pack down nicely, they really attract dirt, which ends up clinging to it. I will use them as dog bowls now and use a non-collapsable metal or plastic bowl for myself when going backpacking.

    Rated 5 out of 5 by from Awesome This is the perfect backpacking cup. It folds flat, so fits in my pot. It has a large capacity, keeps hot beverages hot and cold beverages cold. Keeps its shape when you're using it, and the rim rigid. I've used it for making muffins by placing it upside down in my pot to get the muffins out of the boiling water. It works amazingly well. My only teeny complaint is that the measurement gradations are a bit hard to read, but it only takes a couple of times when you've got the 1/4, 1/3, 1/2 and 1 cup lines down. I've become a real believer in Sea-to-Summit gear. This is another hit.
