The mesh actually breathes, so my climbing rope came out of the weekend without that musty smell it usually gets. I've been using the biggest sack for wet swim gear too, and it keeps the rest of my pack from getting funky.

Bought these to air out my damp sleeping bag after a rainy weekend and the mesh actually lets it breathe instead of sitting there musty. The three sizes cover everything from a wet towel to my whole bag, and they pack down to nothing in my pack.

The three sizes are handy for separating gear, but the drawcord on the smallest sack is thin and slips loose when it's packed full. They do let wet stuff air out at camp, which is the main reason I kept them.
