    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.

    SmartWool Microweight Boxer Briefs - Wool - Men'sis rated4.5556out of5by9.
    Rated4out of5byfromGreat for cycling too.I bicycle toured over 2000 miles with two pair of these. The wool doesn't chafe when it's wet from inclement weather, or perspiration; it cools on warm days, and provides warmth on cool days. If you're not needing padding and tight fitting spandex while in the saddle, but are concerned about chafing on longer rides. I highly recommend these. Even when I'm not touring, I'll wear them on rides longer 30 miles or so. One durability issue that came up; the waistband has started to separate on one of the two pair I purchased. Though they do have a lot of miles and a lot of washes/rinses on them, I wasn't happy to see this happen. Had this not occurred, I would have given these shorts 5 stars for comfort; in this regard, they're the best I've ever tried.

    Rated5out of5byfromComfortable, great for backpacking!I brought two pairs of these on my 21 day backpacking trip of the John Muir Trail. They are very breathable and soft. The most comfortable pair of underwear I have ever worn! I wear one pair while hiking during the day, then switch to the other and rinse the dirty ones. They came from the stream smelling new and dried very quickly overnight. Highly recommend for anyone seeking a comfortable, odor resistant baselayer.

    Rated5out of5byfromPerfectWorn three days, 30 miles, with temperatures ranging from 34-65 degrees F. Fit is boxer brief, not compression shorts. First impression is very soft material. On the trial, nicely absorbent through full temperature range. Material and seams line up nicely--no chafing, even going up hills with loaded pack. After going three days, still were soft and less stinky than anticipated. These are expensive but are worth it.

    Rated4out of5byfromNice BriefsI actually really like these briefs, although I found the fit a little on a big side. I'm 5'11" - 185, 34'ish size waist. Went with the large. The fit was OK, but a little on the loose side on my thighs. After a day of hiking they were a little saggy and bunched up a bit. Purchased a second pair in medium and the fit was perfect. A little tighter, more of a compression type fit and felt a lot more 'secure'.

    Rated4out of5byfromWool briefsThese are very nice, they are also very expensive. I love them and wear them all year round. They are great for camping as they don't seem to smell bad and breath well. There is also some new research which suggests that wool breifs help to keep your lower back muscles warm and thus help ease lower back pain. Try em and see for yourself
