    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.

    by fromDON'T SQUEEZE ME! Initially thought it was a great design but was a little wary of the "zip lock" closure. Sure enough. I followed the directions and tested it for seal but the first time I put it in my back pack I put it inside a plastic bag or the moment I "snugged up" my pack it would've soaked everything I had in there. After fighting with I placed it gingerly in an outside pocket and it survived my simple hiking trip. I hike in hot environments that require I carry a lot of water. This item failed me.

    by fromVersatile and Useful, Requires Skill I have used both the old and new versions of the Platypus Water Tank, both 4L (1 gallon) and 6L (1.5 gallons) versions for over 10 years. I currently own 5 of them and use them for campground camping, multi-day river trips, backpacking, and for my drinking water at a fire lookout. They are easy to fill and to clean, they carry easily, don't leak (when properly zipped), and they pour accurately. And when they are empty, they roll up and weigh next to nothing. I find the Water Tank to be extremely durable. After 9 years of abuse, I finally managed to get one to develop a small leak, and REI replaced it immediately. Now the down side..........1. Getting the zipper closed properly is tricky. The new models sold now are easier to zip than the old ones, but they come apart quicker if you have not yet developed the proper "zen". 2. REI no longer appears to carry the 6L (1.5 gallon) Water Tank. You can still buy it online from other vendors--for about $35. 3. The Water Tank has gotten expensive. Recently, I picked up a 96 oz. (3L) Nalgene Wide Mouth Cantene for $12. It has all of the advantages of the Platypus Water Tank with none of the down sides. Because it is a little smaller, I will continue to use a mix of 3L Nalgene Cantenes and both 4L and 6L Platypus Water Tanks. However, if you are a backpacker, my recommendation is that you go with the Nalgene for your trail needs.

    by fromHelpful Tip This thing is great and I love it; it's so helpful and becomes literally a water friend at campsite. Wether your 20lbs or 50 lbs, this thing is worth the 3.5 oz. of weight. Also other campmates will love you as you can become the water giver! It however could be improved: It is easy to close when empty, but quite difficult to close when full. It would be great if it had a better closure system, maybe a slide lock to help seat the zip grooves, can be frustrating/annoyingly difficult to press as hard as humanly possibly to close. Here's my tip for carrying long distance: I had water a mile from camp, on the way back every few hundred yards the bag would pop open (xtra frustrating as not easy to re-close) after 3-4 times of this happening I twisted the handles 2-3 times under/over itself: it never popped open again! Cascade Designs: great item, please enhance closure and keep under 4 oz. -Aquarious (the water bearer)

    by fromplatypus water tank Bought this mainly to transport and hold water while car camping and backpacking. I bought the 6Liter version so we could filter large quantities of water at once. Worked well out in the back country and has also worked well while car camping. Easy to fill, pour and clean but a little difficult for me to close. My husband doesn't seem to have the same problem. We also have the playpus bladders and they have something that I would call a "zipper" closure. If this tank had the zipper, I would give it 5 stars. Even without it, this is a great item to have.

    by fromA Must-Have for Hikers I would highly recommend this item to any hiker or adventurer. It is the PERFECT camp item. I thru-hiked the AT recently, and this collapsible, lightweight water-carrier was being used by not just me, but other hikers at every shelter. Most hikers carry about 2 liters of water (usually in the form of Nalgenes or Gatorade bottles or even a Camelbak) with them throughout the day, but 2 liters usually isn't enough for camp. Think about when you hike into a shelter for the night. You want to cook dinner (usually a cup or two), drink plenty (three or four cups), wash your pots (one cup), brush your teeth (another cup), and have some left over for the night's sleep. Oh yeah, and add a lot more for breakfast the next morning! The reality of hiking the AT was that some shelters had great water sources that were nearby, but a lot didn't, and some of them (no joke) would take 20 minutes of walking to get to, or take you over 400 ft. of elevation change, and who in their right mind wants to make that trip more than once if they don't have to. I know lots of fellow hikers were using my Platypus bag for just this reason. And if you're Aqua-Mira-ing your water, you don't need to worry about potential fungus. The chlorine will kill it if it even pops up, which in my case, it didn't.

    by fromGreat water container This is a wonderful water container to take backpacking. It is very light and compact yet holds 4 liters of water once you get your camp established. Well worth it!

    by fromAwesome product I originally wanted an MSR Dromedary for camp water supply when backpacking, to save repeated trips to water sources and carrying relatively heavy Nalgene bottles. My wife got me this for Christmas and initially I was kind of disappointed. Then I used it... This thing rocks for backpacking. It weighs nothing and folds to nothing- you dont know its in your pack. You can prefilter water in to it or dunk it to fill it. The cap is a perfect size for controlled (but not boring slow) pouring. The handles are great for toting to camp or hanging up on a tree limb. The plastic seems very tough and I'm sure it is going to last a long time. The more I think of it, the more I prefer it to the MSR I had wanted! My one, only TINY nit pick- the spout cap could use a retainer, like your Nalgene cap does, to stop it getting dropped and lost. Overall, awesome product.

    by fromTested! I initally was very wary of the zip-lock closure. So.. I tested it. I filled it FULL with HOT tap water (think rolling steam), sealed it, and then did a 2 foot drop test onto the floor. I did it several times.. Not one drop leaked from the "Tank"! I've now used it for many 40 mile + trips as my in-pack reservoir (place vertically in the sleeve) and it has never leaked. Mine weighs 3.6oz (103g) and really comes in handy around the campsite.
