Ultra-Sil 背包套 (如新品)

For something that disappears into my palm when packed, it kept my whole pack bone-dry through an afternoon of random mountain showers — the medium barely registering at under four ounces on the scale.

Pulled it out of the stuff sack and was shocked at how light it really is—under four ounces feels like nothing on the pack. The medium fits my 45L bag snugly enough that it stayed put through a windy ridge, even with the straps cinched.

Got this "like new" and honestly can't tell it was ever used. The whole thing scrunches down smaller than my fist, which is a relief since my pack is already stuffed. Tossed it on during a drizzle and my gear stayed dry, though I haven't tested it in a real downpour yet.
