Osprey Drybags – lightest ones?

I've used the STS Ultra- sill bags for the past several years. Recommended.

I have a few Sts bags. My smaller one always seems to end up wet on the inside when exposed to anything but a light mist. I just picked up a few of the Ospreys to try out but no use time with them yet. I realize neither are for submersion but I'm hoping the osprey seals a little better.

I've used a STS ultrasil bag as a food bag hung in a tree overnight is one heck of a storm…basically 6+ hours of solid rain. Still dry on the inside. The material is very similar to that used on the rain fly of the BA Fly Creek Platinum.

The seam tape came off in one piece after a short period of time with the 4L bag I had. Abraded a hole really quickly on the 13L bag and finally blew the bag apart at the seam using the 13L bag for my sleeping bag. A little too light IMO. Both were the Ultrasil version.

the OR UL ones come with OR's infinite warranty

on UL sacks, you may want to have a no questions asked warranty …. they are quite a bit less burly than the "traditional" dry sacks
