Vetted Review: Is it silly to love compression sacks? We don’t think so and here’s why:

When my wife first started tagging along on the trail with me, she said no way can you fit so much gear into one pack, especially with the size of a bulky sleeping bag! Challenge accepted. The name of the game is compression sacks and Sea-to-Summit has the best one around.

1. SAVES SPACE Compression straps make it easy to evenly compress soft items making more room for gear in your pack.

2. ORGANIZATION Keeps everything in its place and easy to stack and grab quickly especially with their fast easy to use compression strap side-release buckles.

3. WATERPROOF Made from a super high tech fabric that’s both waterproof and air permeable allowing air to push out but water can’t get in. The roll-top closure is also an extra measure to keep the water out.

4. LIGHTWEIGHT Ultra-lightweight, bluesign® APPROVED Ultra-Sil 30D Nylon main body fabric with a PFC-free DWR finish, helps keep your pack light (assuming you don’t over pack with all the extra room you’ll have from compressing all of your soft gear).

5. MULTIPLE SIZES 6-30 liter sized options at your disposal

Innovative high quality compression sacks really do make a difference when packing your gear and getting it all to fit, especially for longer treks or in transitional weather where you might need more or less layers of clothing.

If you don’t need compression style sacks, sea to summit has tons of other great storage bags to offer as well:

- Stuff Sacks

- Mesh Stuff Sacks
