    REI Members get back an estimated 10% on this item as part of their annual member refund.

    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.

    Thorlo Trekking Socks is rated 4.0 out of 5 by 2.
    Rated 5 out of 5 by from My favorite heavy sox! I have used these sox for years now and just ordering two new pairs. I always used to wear 2 pairs of socks to avoid hot spots and for cushioning. since i started wearing these I just use 1 pair. They are extra thick in the right places, and will remain comfortable for years. I love to wear mine when I back country ski in the mountains, I never worry about cold feet. I finally have worn a small hole in the toe of one of my old pairs, unbelievable service for many years of hard use, winter and summer.

    Rated 3 out of 5 by from Too Thick I ordered two pairs based on the positive reviews here. The socks seemed well made and were very soft and comfy, but they were so thick they wouldn't fit in my boots. I didn't see this mentioned anywhere so I wanted to add this warning. They'd be great if your boots are sized for such thick socks. I'm sending them back and will try the Thorlo "light" socks instead.
