    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 of5byfromGreat HatI bought this hat to hike in. It is very light weight and comfortable. I would highly recommend it to anyone looking for a great outdoor hat.

    Rated5out of5byfromGreat hatLove this hat. Bought it for recreational kayaking & day hikes - great against sun and at least light rain. Packs great (which is how I lost the first one I owned in Iceland) and still looks good. I don't like anything else I found on-line as well as I like this one.

    Rated4out of5byfromnice qualityQuality seems better than other hats I've had. Agree that it is a bit nerdy but it serves it's purpose. I measured 24in for hat size which is xl for this hat, but it still seems a bit large (drops down over my ears. sort of have to tuck them in) but after using the cinch it feels comfortable. So far seems to be a keeper.

    Rated5out of5byfromKeeps the sun off, breathableI'm a letter carrier, and I use this hat on every sunny day in the warm weather. It keeps the sun off of my face, neck, and ears. It is very breathable, more so than my baseball cap. The material seems strong. I am very happy with this purchase. The brim tends to lose it's shape, but that's to be expected with a soft brimmed hat.

    Rated4out of5byfromPleased with this choiceThis was a great choice for backpacking 12 days in the New Mexico sun. Was lightweight and comfortable. Crushed in my backpack, when taken out it bounced right back to its original shape - especially after a soaking rain. Not listed as waterproof, but did an acceptable job of keeping light rain out of my face. Usually my head is big for hats, but I followed the sizing guidlines and XL felt a just a touch big. This really wasn't a problem as the cinch at the back completely corrected the fit and in retrospect, I was probably appreciative of the slightly looser and more ventilated fit. At the end of the hike the hat was filthy, but came completely clean in the wash. The style is a little nerdy and floppy, but in that kind of sun, function over style is definitely called for.

    Rated5out of5byfromMy favorite hatThis is my favorite full brimmed hat. I wear it pretty much any time I'm outside. Packable and keeps its shape. Waterproof - I wear it in the pool too. Great all around hat!
