Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


Keep your backpack organized without adding excessive weight. These ultralight compression sacks have a slippery exterior to help you shove them into small nooks in your pack. The lightweight fabric has a waterproof coating to shed rain, but there are no taped seams or roll-top closure so it's not fully waterproof.

  • Silicone-impregnated ripstop Cordura® has 2000mm water-resistance
  • Cord lock top closure
  • Double-stitched seams and bartacked stress points add extra strength
  • Bottom handle for easy carrying
