    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.

    Questions? Call us at 1-800-426-4840 for more about your dividend or its redemption.

        Comments about Cocoon Silk Mummy Liner:

        It was supposedly Spring, yet I figured I'd bring this silk mummy liner along with my lighter weight down bag - just to try it out.

        I'm glad I did. My bag was rated to 40 F, and the temperature dropped to that. The silk liner made it comfortable, and probably added a couple of degrees of warmth. If it was hot in the Summer- it would be great to use and sleep on top of the sleeping bag. I'll try that next.

        Unpacking it was easy, but I was surprised in the morning how easily I was able to just stuff it back into its little sack. It's exactly like a magician stuffing a silk handkerchief into his hand. Poof! Gone.

        When I got home, I unstuffed it, and refolded and rolled it back into the bag. I love its compact size and extremely light weight. I'm planning to walk the El Camino de Santiago in Spain, and I am definitely taking this for use in the pensiones and guesthouses.

        It's also a nice way to keep your sleeping bag like new by using a liner like this.

          Comments about Cocoon Silk Mummy Liner:

          I've used this silk liner for the last three years on all my backpacking trips.
          It's soft, yes, adds some insulation, yes, but the best thing about it is that it keeps my bag clean. When I backpack, I am not the cleanest after a couple days. The sweat and grime transfers to the liner, not the bag when I sleep.
          After the first year, I dyed it brown so it wouldn't look so dirty in the field.
          It's easily hand washable, and it drys quickly.

            Comments about Cocoon Silk Mummy Liner:

            So far I've used the liner backpacking in Patagonia for about 17 nights in the back country. It has held up well so far- no signs of wear. I have a 20F down sleeping bag and brought the liner with me in case it was really cold, and to keep my sleeping bag clean. It wasn't that cold (probably a minimum of 28F on our trip) so I was never cold, but it seemed like the liner was increasing my sleeping bag warmth

              Used on multi-day bike trips. I'm 6'1" and it fits me fine. It added some warmth (~5 deg F as advertised) to my bag during some 30 degree nights.
