    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.

    Deuter ACT Lite 40 + 10 Packis rated4.3333out of5by12.
    Rated4out of5byfromGreat packThis pack is really comfortable. The only downside for me is that while it does have a sleeping bag compartment it's top load. It would be nice to have a zipper and be able to lay it down and unzip to get to stuff. As it is you have to dig in it or dump everything out. Other than that it is functional and comfortable fully packed.

    Rated4out of5byfromBig Pack in a Small PackgeHave hiked with this pack on the AT for 628 winter miles so far. It can carry enough gear to operate down to zero F with five days food. It's a profoundly comfortable pack to carry with ample room for essential gear, but no extras. Compartments facilitate organization. Has only one hip belt pocket into which you cannot see while wearing the pack. Needs more, larger and better pocket placement on hip belt and outside of pack. This pack leaks like a seive even with a rain cover on. Seam sealing and water resistant zippers would be a huge improvement. The buckles and keepers need tabs that would enable them to be enable them to be operated while wearing gloves or mittens.

    Rated4out of5byfromPacking the Milky WayMy wife and I each had the same pack and used it for the first time on the Camino de Santiago in Spain. Very versitile, but needed to constantly adjust the straps. Worked great with our Osprey water unit. Lots of places to store and attach stuff. Easy access to bottom of the pack. Also, easliy stowss in airplane overhead luggage compartment.

    Rated5out of5byfromDurable, comfortable, and great designI initially bought one of these for work. I drive buses for Metro, and needed something to carry around work required materials, two liters of water, lunch (with ice packs), plus some minimal first aid and other supplies. And a collapsable contact staff to play with during breaks; the design of the inner pocket accomodates something that long! And I needed something I could strap a portable seat cushion to. Even with as much as I carry on a daily basis, with the seat cushion strapped on the back, this backpack still balances very well ergonomically. The straps are very adjustable for many body styles and sizes, and well padded. I liked it so much, I bought a second one a year later for non-work purposes. I've packed it full for overnight trips, including strapping a mattress pad and tent onto it using the cinch straps, and stuffing a sleeping bag inside. Not a single tear on either pack, nor a single problem with the zippers. The mesh in the back even holds up to my cat scratching on it if I leave it on the ground too long. Easily the best backpack I've ever purchased.

    Rated5out of5byfromThis Pack RocksStarted out wanting to downsize from a 55 liter to 40 liter pack for our 3-4 day trips. Didn't like the Osprey and Gregory options for ventilated packs that move the weight way too far off your back and make the load unstable. Dueter has a nice option where they allow for enough ventilation while keeping the load closer to your back in a more stable place. Love having a smaller lighter pack. Not as many access points...but it is a balance of benefits.

    Rated4out of5byfromgreat pack, but it's a little too smallWe set out to get a pack for my 12yo son for a weekend backpacking trip, but keeping in mind future trips including a week long trip to New Mexico with the scouts in a couple years! For the weekend, I split our gear, mostly food and cooking equip between myself, my 12yo, and my 8yo...keeping the 8yo pretty light. I took the brunt of the load, but even so the 12yo's pack was LOADED! And this was only for a weekend and we packed pretty sparingly! I had an 80L pack and I was very loaded, but it fit what we needed much better than the 50L. In hind site, we should have gone with a bigger pack...probably the 80L. I was less than thrilled about the tie on points. I was much happier about tying onto my external frame pack. Much easier.

    Rated5out of5byfromLove it!I love this pack. I have a torn disc in my lower back and deal with chronic pain everyday. It's hard for me to carry more than 10 pounds, but this pack allows me to do so. It's got amazing comfort straps and support. I would definitely buy it! Good luck!
    Date published: 2013-08-14
    Rated4out of5byfromLots of adjustabilityGreat adjustability. I'm 6'2", 165 pounds and I had to return my other pack for this one because I couldn't cinch it tight enough around my hips. This one has enough adjustability for me and even more in case I ever get skinnier :) Only con is that it's only available in red and black. Black is too hot and red is not the greatest color, but function over fashion, I guess....
