    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.

    Seirus Hyperlite Stormsocks Waterproof Socks is rated 2.75 out of 5 by 4.
    Rated 2 out of 5 by from Not for Wet Weather These were a Christmas gift, so I shouldn't be complaining. If you keep these socks dry, then they will work as intended. However, once wet, they are basically useless. They do not have an elasticated cuff, so when you stretch them to put them on, and then they get wet, the cuffs droop, funneling water into your shoes. A DWR treatment may help with performance, but as is these have no water resistance. Once wet, your thermal barrier is lost as these are super thin = cold feet. I would recommend spending the extra $ for a goretex type sock, if you are wanting something with water resistance.

    Rated 1 out of 5 by from NOT Waterproof I bought these specifically because I needed WATERPROOF socks for cold weather kayaking. They are not even close to being waterproof; the fabric may be slightly water resistant, but the seams leak like sieves. As others mentioned, they have basically no stretch, so they are hard to put on and slip down, but I could live with that.

    Rated 4 out of 5 by from Good water socks Bought these for a trip to Utah to use for cayoning/canyoneering. I typically wear a size 10 shoes, and these were a little big. Not sloppy big, but they top of the sock loosened up a good bit in the water and fell down. This allowed for sand and other small debris to get into my boots. A minor detail and nearly unavoidable, but thought I'd mention it. Overall, a great water sock. No hot spots or blisters from rubbing.

    Rated 4 out of 5 by from Great for wet or cold bike rides & walks I've had one pair of these for years, and ordered this new pair recently to have a spare. Sadly, the new pair is smaller than the old pair, though marked as the same size (XL.) I wear these over a pair of merino wool socks in my SPD clip-in biking sandals, which keeps me warm enough to ride down to 30 degrees. Kind of pricey, but highly recommended. I only wish there were an even larger size available so I could get them on more quickly and easily.
