    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.

    Arc'teryx Altra 85 Pack is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Wonderful PAck This Pack is wonderful. It is a little overpriced but seeing no other pack can offer the size, comfort, and quality that this one can, I can live with that. This a great bag for long hikes if you like to carry a lot of gear. I like to carry the whole tent, water pump, and stove to make things easier on my girlfriend and this pack simply swallows the gear. The kangroo pocket on the front is great if you have lots of things you want to have quick access to. Water Pump, first aid, flashlight. The clips under neath making stowing a jacket mid walk easy, never again will I leave camp without a jacket on just because I don't want to deal with packing it up 2 hours alter mid hike. The water pockets on the side will hold a 1 liter nalgiene each without any trouble or you can put a camel-bak in the water pocket inside the pack. The best for last, the swiveling hip belt will blow your mind. It supports the pack so well, I used to find myself stretching my spine every time i stopped but not anymore. The pack drives all of the weight to your hips and the swivel makes it so your back is not fighting the pack as you walk or take big steps up. It is very comfortable. I was weary when I bought this pack do the lack of reviews and I promised myself I would review it after my first 2 hikes so other people would not be so in the dark. This a great pack, if you can handle the price you will LOVE the pack.
