    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.

    MSR AC-Bivy is rated 3.0 out of 5 by 3.
    Rated 4 out of 5 by from Solid shelter I bought the MSR AC Bivy for my hike of over 1000 miles on the Pacific Crest Trail this year. This bivy was my shelter nearly every night for over 3 months, and I never got tired of it. I particularly enjoy laying out under the stars, yet being sheltered inside the bivy from the elements and insects. The envelop design with a mesh panel allows for celestial views, and makes it easy enough to slip in and out of. A tarp also accompanied me in case I had to weather any serious precipitation, and I would carry one in addition to the bivy on future hikes. However, I hardly used the tarp on the PCT as most often the bivy was sufficient shelter. I find the bivy adds several degrees of warmth to my sleep system, and often cut the chill from wind. In high winds, though, the bivy helps little and often the hood billows up when it catches a strong gust. A loop on the lip of the hood allows it to be guyed out, potentially reducing billowing. The MSR AC Bivy is an efficient shelter and I recommend it to any backpacker looking to shed some weight from their pack. I will be taking this bivy as my shelter on future hikes, including a thru-hike of the Appalachian Trail next season.

    Rated 1 out of 5 by from All in your face Used this camping on a 6 month trip. Having previously owned a MSR Advanced Bivy which I loved, I didn't realize how important the single pole was in keeping the bivy off your face and creating space. The design of the AC Bivy means that unless you tie it to an external point such as a tree, the material rests on your face. This leads to several other problems. Condensation is extreme, wind blows the bivy open, rain gets in easily, turning in your sleep shifts the opening, mosquitoes can bite you through the mesh as it rests on your face... The only practical use I found for the AC Bivy was keeping a down bag dry when sleeping inside a tent.

    Rated 4 out of 5 by from It's huge The other reviewers of this product seem to be above 6 feet and 240 pounds. If this one had a pole, I would feel like it was a one-person tent. I'm 5'5, 130lb. Even understanding that it's designed to have tons of room behind your head, I don't like the amount of fabric billowing over my face and bunching at my feet. It's incredibly lightweight and well made, despite all that. If you're a big guy you'll probably love it.
