Zpacks Medium-Plus Stuff Sack

The Zpacks Medium-Plus Stuff Sack is made from Dyneema Composite Fabric (DCF), the same waterproof, non-stretch laminate Zpacks uses in its packs and shelters, closed with a simple drawstring rather than a roll-top or zip. Its Medium-Plus sizing is meant to pack clothing or a tent lying horizontally across a backpack, rather than stacked vertically the way a narrower stuff sack would sit. DCF's main advantages here are that it doesn't absorb water and holds up to abrasion better than standard nylon at a similar weight, though it's stiffer to pack down small than a compressible nylon sack. No weight is listed for this specific size, so if that matters for your base weight tracking, check the current product page. It suits ultralight backpackers already using DCF gear who want a stuff sack that matches the durability and water resistance of the rest of their kit.
