    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.

    Rated5out of5byfromWorks greatBought this for my son and he has used it on several camp outs since last summer. We just hiked the approach trail to Springer Mountain in GA and he loved the fact that he didn't have to reach around his backpack to get a sip of water. I, on the other hand, had to reach around, get my bottle and struggle to get it back into the holder on my pack while walking. He likes his so much and talked about taking a sip whenever he wanted, that I am going to get one for myself!

    Rated5out of5byfromGood productGood quality hydration pack. Platypus makes a good product overall. The prior pack I had lasted me for years. Also nice is that they sell parts for these so, you can just replace the tube, bite valve etc as needed. This is a bit pricey,>$20 but worth it in the long run. I've had too many cheaper brands develop tiny cracks in the bag and become useless.

    Rated5out of5byfromPlatypus great alternative to CamelpacksI had Camelpacks before, and found them too expensive. When I found this solution with interchangable pieces between bag sizes and drinking tips, and replacable parts at very reasonable prices - I was hooked. I have used these repeatidly for at least 10 different hikes and they are holding up very well!

    Rated4out of5byfromEffective Water PackThis is one of the hydration packs that I have used which doesn't have a plastic taste. That alone will receive a good rating from me. This pack as well seems to be built simply and well with durable materials. I would recommend it to anyone.

    Rated2out of5byfromdon't buy itthis replaced a camelback bladder. it leaked after 3 uses. and the opening is small so you can't get ice cubes in it. bad choice.

    Rated1out of5byfromNot ImpressedI bought this to replace my old Camelback. It had been years since I owned a Platypus. I made the mistake of taking it on a hike without testing it. The mouthpiece did not work. I had an aluminum bottle along to give my dog water and I had to pour water from the Platypus into the bottle. I took it back and got another Camelback. Camelback has upgraded their design since my old resevoir and it really works great.

    Rated4out of5byfromeasy to use and easy to storeI take two extra hosers without the hose (with just a cap) along backpacking to use for extra water when I know we won't be near a water source. When empty they fold into a very small space.
