Review on 🌊 Sea to Summit Ultra-SIL Nano Dry Sack: Featherlight Waterproof Bag for Ultimate Protection by Christopher Bacho

EDIT again: StS responded to my issue with them very quickly. It looks like the 1200mm head spec might not be enough for them to keep the sweat off them while running. Remember. With the non-nano version, you get almost twice the water resistance for a bit more weight, and even for a lighter weight, it's probably better to try. EDIT: I liked them at first. Light. pretty hard. Easy to use. But after about 10 uses, I noticed a fairly significant problem: IT IS NOT ACTUALLY WATERPROOF. I use them to keep my gear dry in my running pack on long runs. My backpack is mesh, so an extra shirt, phone, wallet, etc. goes in it. However, for the last 4 or 5 runs I've had raw gear every time I took things out of my bag. This includes only 1 actual run in the rain. The other runs were on dry days and the only moisture that got into my pack was sweat dripping off my back into the mesh. But somehow it ends up in these bags. All (2 liter and 2x 1 liter bags that I have). I always close them carefully according to the instructions with at least 3 rolls before zipping. Today I put in the least as a test and got 4 rolls before attaching. When it rains I zip it up in my backpack, the durable bottom with taped seams stands up to the rain. There was no rain. It got warm and sunny. I started sweating. When I got home I emptied my bag of spare shirts. Both felt wet. Not wet, but wet. It wouldn't kill me, but the humidity after 2.5 hours of sweat exposure? Let us. He opened a bag containing a wallet, a phone and a first aid kit. drops of water inside. Wallet (leather) is clearly wet. The phone is oily from moisture. I have no idea why they can't really keep my stuff really dry when it's just exposed to sweat or light rain, but I wouldn't fucking trust them with a real downpour. I hope Sea to Summit brings them back or something. You are really disappointing. If I'm paying $16-$20 for a tiny bag that gets premium money because it's supposed to be waterproof, it's actually better that it's waterproof. It's not like this.
