    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.

    Sea to Summit Reactor Thermolite Mummy Bag Liner is rated 4.0 out of 5 by 23.
    Rated 4 out of 5 by from roasty toasty i've only had one opportunity to use this since i just purchased it, but so far, so good. we camped in 20 degree weather and my husband had to shed his after getting too warm (we also have 0 degree bags, but they are ~15 years old) so i doubled up and had the best camp sleep ever. he would likely leave a less glowing review since he is a human radiator and also like to turn cartwheels in his sleep and found the liner a bit too confining. typically, we zip our bags together which gives him a bit more room to kick me in his sleep, however, since these are super light, there are no zippers to combine them so he was additionally confined to his own sleeping bag (probably another reason i slept so good!). short story long - i loved the liner, but he would probably have a different story.

    Rated 5 out of 5 by from Lifesaver I bought this liner for a trip to a White Mountain hut. It was expected to be -10 degrees or lower and I only have a bag rated to 18 degrees. The liner worked like a charm. It was exactly 0 in the hut, but the liner kept me warm all night. Brilliant.

    Rated 4 out of 5 by from Great for when you're just not sure. I went hiking/camping last weekend and almost did not bring this along due to a warmer than average weather forecast. Ultimately, I decided it was so light it was worth the extra few ounces. Around 3 a.m. the wind on the mountain really picked up and it was cutting right through my sleeping bag. I pulled this liner out and and almost immediately felt the difference. This made the difference between a miserable night and being too cozy in the morning to want to get up.

    Rated 5 out of 5 by from Nice & warm Use this in my 20 degrees bag when it gets below freezing. I'm a cold sleeper & this does add warmth. Also nice to keep my bag clean(er).

    Rated 4 out of 5 by from Compact and versatile I bought this bag for several reasons, but primarly for a lightweight and warm weather bag. I'm in NC and do most camping in NC and it's warm here most of the year. I bought this bag/liner and have so far only used it alone. And that's what I wanted it for. It's cozy to sleep in and just right for warm weather camping. In "cool" weather, I've used it with a space blanket over it and was fine too. I haven't yet tried as a bag liner, but based on its solo performace I'm sure it will add a few deg of warmth to my mummy bag. I also keep it in a survival pack in my trunk when not camping.

    Rated 4 out of 5 by from Great purchase! I recently took a trip to Yellowstone and did some backcountry camping. The temperatures got down to the mid/low thirties overnight and I knew from previous (and uncomfortable) experience that my sleeping bag wouldn't keep me warm enough. I purchased this liner to supplement my sleeping bag and it totally worth the money. It's very thin and lightweight so I was concerned about its effectiveness, but I was incredibly comfortable and warm all night. The fabric is also very soft and cozy and added minimal weight to my pack.

    Rated 5 out of 5 by from Warm & Comfortable I bought this for a 7 day Kilimanjaro trek & was SO happy to have it when the zipper on my rental sleeping bag broke. It was super warm and comfortable and I found it very easy to get in & out of in my small tent. Probably my favorite comfort item the whole trip!

    Rated 5 out of 5 by from Great addition to mummy bag, plus. Great addition to a mummy bsg for cold weather conditions and offers versatility as a warm weather bag all by itself. Excellent light weight option.
