    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.

    Questions? Call us at 1-800-426-4840 for more about your dividend or its redemption.

    by fromStrawberry Bannana Tried the Strawberry Bannana after a hiking around Enchanted Rock. Its pretty think and I didn't enjoy the taste. The other flavors may taste better but i think the thickness will be the same. I prefer the honey stinger taste and consistency.

    by fromBanana Strawberry is INTENSE Dang, this is NOT lacking on flavor. I'm not sure how 'many' bananas/strawberries they had to use to get the "natural banana flavor", but holy smokes! This little guy does not leave you wanting in the flavor department. This is basically the same consistency as taking a shot of honey. My stomach made some funny gurgling noises not even three minutes later, so we will see what that is all about later. Ya, this one is SUPER banana flavor. I may not get this one again. I love banana's, but this is a bit much.

    by fromHey! That's pretty good! Tried the "Peanut Butter" out of curiosity and was pleasantly surprised. It actually tasted like peanut butter but not quite as intense or as "gooey" as the real stuff. 2 thumbs up.

    by fromWorks as it should My highschool running coach used to give me this before a distance running. He swore by them. I now am a believer in a GU. I don't really know how it works or the nutritional contnets, but it DOES provide a boost when needed. Like any kind of gel, it makes you thirsty like crazy, so drink alot!

    by fromMy top gel Months ago I went out and bought two of almost every brand of gel I could find in the store. With long training runs and a lot of races I get to use gels fairly often. I recommend that you personally try a few different brands and flavors to find what works best for you. My taste buds and stomach say one thing, but yours say something completely different. With all that said GU is my favorite gel out there. They have a good selection of flavors, my personal favorite being espresso love. I find that GU’s tall and skinny packages fit very well into a pocket or a water bottle holder. Once you pull it out of your pocket you can very easily bite the top off, its also very easy to take that piece and put it in your pocket so you don’t litter. These are clean and easy to get from the tube to your mouth. The only complaint I have is that it has become very hard to find GU without caffeine in it. Sometimes I might want a caffeinated gel, but if I don’t want caffeine I have to turn to another brand. If you want to know how much of a boost these give you I would say that there is very little difference between gels, but this one seems to be identical to the other brands I have tried. Just like most gels, too many of them will mess you stomach up a little.

    by fromGood gel I feel gels are best in endurance sports for the convenience. Unlike other brands these containers are durable and will not leak. Used to make a large version that filled a bottle but now have to use 3-4 to fill my bottle.
