Ultra-Sil 收納袋

I’ve been using this sack to separate my wet rain jacket from dry clothes, and the water-resistant coating actually holds up well—no dampness leaked through. It’s impressively light and packs down to almost nothing.

The 30D nylon feels way thinner than my old stuff sacks but it's held up fine after a month of cramming it into my pack. I use the small one for my cook kit and it keeps everything dry even when my water bottle leaks. Weighs basically nothing, which is exactly what I wanted.

Used this to separate my tent stakes and cook kit from my clothes, and the 30D nylon feels way tougher than the weight suggests. The DWR shrugged off a damp stuff sack situation in my pack without soaking through. Barely notice it's in there.
