A thru-hike dry bag is a liner or a roll-top that keeps a quilt dry when the pack is not. It is not a river barrel.
Sea to Summit Ultra-Sil 8L is first: the roll-top most shops stock. Hyperlite Stuff Sack is the Premium Pick — Dyneema, the same fabric as the pack. Nylofume is Best Value: a dollar liner that still keeps a quilt dry.
