泡棉坐墊

The closed-cell foam didn't soak up a drop of water during three days of rain, so it stayed light in my pack the whole time. Tossed it down on wet granite for lunch and it kept my pants completely dry, honestly better than I expected for something this minimal.

I’ve used it as both a seat and a knee pad on muddy trails, and the fact that it’s this light never stopped it from taking a beating. Even soaking wet, it stayed comfy and didn’t weigh me down.

The foam’s density is just right—firm enough to keep my knees dry when I had to crouch over the stove in the drizzle, yet soft enough for a proper lunch break. Packed flat in my bag and I forgot it was even there until I needed it.
