Sea To Summit Ultra-Sil Compression Dry Sack

We currently have 5 in stock.


It’s an ideal option for use inside a backpack during longer lightweight hikes, adventure travels, cycle touring and any activity where you need to maximise pack space by compressing your bulky items to one-third of their volume while keeping it dry. It employs waterproof seams, a non-wicking roll-top closure and is super lightweight.

  • This valve-free dry sack uses an air-permeable base made of waterproof eVent® fabric, which allows air to be pushed out, but keeps water from entering
  • Waterproof seams are double stitched and fully taped for excellent durability and resistance to moisture
  • Roll-top hypalon closure with lid and 3 straps evenly compresses and maintains compressed size
  • The Sea to Summit Ultra-Sil Compression Dry Sack is roughly half the weight of the original Sea to Summit eVent Compression Dry Sack
  • Field Repair Buckle can be replaced with just a screwdriver
