The Ultra-sil stuff sack is ideal for better organization of stored items in a backpack or suitcase. It is very light, resistant to splashing water. It is not intended to water, so it does not have taped seams or a roll-up closure. It is suitable both for storing a tent, sleeping bag or other equipment, as well as for small things such as documents, cables or clothes. It is made of Cordura, a material resistant to mechanical damage and has double-stitched seams. It is equipped with a handle that makes it easier to carry, has a drawstring closure and thanks to the sliding outer material, you can easily insert it into tight spaces.
