Customer Reviews for the Ultralight Outdoor Research Dry Sack

5 StarsLinda Bourgault - July 30, 2009

Worth the price
I have used my OR bags several times. They are light, they make organizing gear easy, and although I have only used them once or twice at this point - they look durable. They are a little fussy to close tightly because of air bubbles, but then the hermatic seal is the point after all. If they put a valve in it, it would cost more and add to the weight.

Good dry bag for kayaking
Dry bag is very lightweight and appears to be quite durable. It is reasonably waterproof in rain and splashes, but expect some whater to sip through on complete immersion. This is pretty much true for any dry bag I tried in my kayak. Overall a good choice.

Forms leaks quickly
If you have anything that scuffs or rubs the inside surface of the bag, they will not remain waterproof!!! This is the downside of an ultra-light bag. I took two brand new bags on a 2 week outing. The larger bag was used for my clothing, and the smaller bag was used as a food bag. The food bag contained the usual goods including several Mountain House freeze dried food packages. I rinsed out the bags after coming home. The smaller bag has developed countless areas of 'white waxy haze' on the inner surface of the bag. I believe are scuffs from the sharper edges of the Mountain House packages which are scraping off the silicone lining. I could apply McNett's silnylon repair sealant, but there are just too many scuffs to count, and I'm sure I will not get them all. I filled the bag with some water, and indeed, there are many many many leaks. There are only a few (3 or 4) tiny white scuffs (1mm in size) on the bottom of the larger bag, and when filled with a small amount of water, there are about 4 leaky spots at the bottom of the larger bag. I'll apply McNett's Silnylon repair sealant on the larger bag, but I'm confident these bags will continue to develop leaks in the future. BOTTOM LINE: Yes, they are waterproof when you buy them. But if anything scuffs the inside of the bag (zipper, multi-tool, or any hard sharp edge), you will lose the waterproofing. Just because they don't tear doesn't mean they will last in function. I'm tempted to fork out the $$$$ and have a try at Granite Gear's new Uberlight CFT3 bags.
