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 fromPoor Customer Service I would not recommend this product. I was never able to get more than a slow trickle to pass through the filter. I contacted Sawyer and sent it back. They returned it and it is no better. I've contacted them again and they've stopped replying to my emails. I've never even used it outdoors, I couldn't get it to function when I was testing it. For the price, they should provide better service or honor their lifetime warranty.

by fromGood for small and large groups Troop 1020 just came back from a week hiking in Colorado with 17 Boy Scouts. Had 2 of the Sawyer and plenty of water. The gravity bags were great, fill, leave to filter, fill water bottles, and repeat. 20 - 25 gallons of water per day through the filter without any problems. (We also used tablets.) A learning to pass along, back flush the filter often (even from "clear" streams). This will keep the flow rate fairly high (about 10 minutes/gallon). I would use a mesh bag to keep all of the pieces together on our next trip.

by fromWorked flawlessly Worked great right out of the box. Got to camp and filled the grey bladder from the creek. Attached the filter and got 4L in just a few minutes. Filled the bladder three more times and had no trouble with it.

by fromBest backpacking filter on the market I have used several different filters (pump and gravity) for backpacking, and the 4L Sawyer complete system is by far my favorite. I wanted to abandon the pump as soon as gravity-feds came out, but it took me a while to find the right gravity fed.The first gravity fed I tried was the Katadyn, but it was too slow and very hard to fill up in a shallow water source. Just poor design overall.So I spent a little more money and got the Platypus. The dirty bag/clean bag is great, and it's light, but again very hard to fill in a shallow water source and the zip-lock tops aren't very secure.Finally I tried the Sawyer 2L because the dirty bag had a rigid opening and handle that made it easy to fill in shallow water or fast moving water. The Sawyer also filtered extremely fast. As advertised, I always got 2L in 1.5 min. It's light and you can go even lighter by ditching the clean bag and filtering straight into containers, but I usually carry the clean bag too because it's convenience is well worth the few ounces of weight.I'm just now starting to use the new 4L Complete System. The 4L has a new design that's better than the 2L. The new design allows the clean bag to hang with the filter on top and opening on bottom, and adds a pour spout cap, two improvements that greatly add to the convenience of the system. Also, the 4L size is ideal even for one person, but especially if you're filtering for more than one. I noticed they also came out with an 8L, which looks great for large groups.Finally, in case anyone else has noticed, REI.com seems to have two different Sawyer 4L complete systems [...] Not sure if this was a BETA product, but the specs seemed the same if not better on the Grey/Blue filter and it's the one I've always used.

by fromGreat Filter This filter works very well and did not clog at all. I took water from a mountain lake and it filter it without a problem. This is really designed for using with large groups and not really for a solo hiker or thru hiker. It is a little on the bulky side. Besides that, I would highly recommend this to anyone needing a good reliable filter for a group of hikers.

by fromHands free water treatment Used this system on a four day trip with 8 other guys to Isle Royale NP recently; quickly & easily filtered 4 liters plus per person per day without any issues. The group voted my Sawyer filter system the best new piece of gear they had seen in a long time. After filtering for the group I clipped on the drinking tube and used the clean bladder as my hydration bladder in my pack! Flexible, efficient, easy to use system, get one!

by fromExcellent My partner & I have traveled a lot in India/Nepal & we do not want to add to the extensive pollution with a trail of plastic bottles. We used a pump filter & although excellent, took time. We gave this one to a friend living in Kathmandu who writes, "The water filter is working like a charm!!! I am never out of water, and its so easy because it just works with gravity! I just use tap water---nothing else required. And i know its good--and no illness! I would highly recommend it. Just maybe bring coat hangers or something because one of the bags does need to be higher than the other." If we stay in Asia for extensive time again, this filter is the one.

by fromFlawless After researching various filtration systems, and based in part on the reviews purchased this for a 5 day hike in Yosemite. Great for groups of 3 or more as it filters large volume of water quickly. Had our 3 liter hydration packs refilled and enough water for camp cooking/cleaning within 30 minutes. Filled from streams, lakes and ponds with no bacteria problems. The handles do seem a bit flimsy-will see how well they hold up with repeated use.
