SEA TO SUMMIT Ultra-Sil eVent Compression Dry Sack M Purchased in 2018. Used about 6 times to compress a down sleeping bag, and then stored at home. I am selling it because I don't plan to use it anymore. The eVent logo is faded from rubbing against a backpack. I haven't used it in about two years, so I checked the waterproofness just in case. (I wet the outside until it was soaking wet and confirmed that the towel inside did not get wet.) Since it has been several years since the purchase, I am selling it at a slightly lower price. Please consider this item with the understanding that it is a used item. I strive for prompt shipping. The following is a reprint: This is a lightweight compression dry sack made of Ultra-Sil nylon. By using "eVENT" on the bottom, the functions of a waterproof sack and compression are perfectly combined. It is ideal for stuff sacks for clothing, sleeping bags, etc. ● Functions: Fully seam-sealed / Roll closure system / Double-stitched reinforcement ● Materials: Highly breathable waterproof material eVENT (70D nylon) / 30D Ultra-Sil nylon ● Capacity: (Maximum) 14L - (Minimum) 4.5L ● Size: φ20 x 46cm ● Weight: Approximately 90g ● Color: Gray
