The Compression Sack is the perfect solution for squishing down bulky soft items for organized packing. These burly sacks are built from a water-resistant 70D Nylon fabric, offering excellent strength to weight. They can allow compression down to one-third of their original volume, which means you save valuable space in your pack for other essentials.


In a perfect world, with perfect contents this compresses down to 1/3rd of its original volume (i.e. from 15 to 5 liters)
