Mountain Stow vs Stow: Which Collapsible Bottle Fits Your Pack?

Quick answer

Choose the Mountain Stow 350ml for ultralight pocketability or the Stow 1L for longer trips where you need more water without sacrificing pack space.

Mountain Stow vs Stow: trade-offs at a glance

• Capacity: Mountain Stow holds 350ml (about 12 oz); Stow holds 1L (about 34 oz). Choose the Stow 1L if you need sustained hydration on a longer hike.
• Weight savings: Mountain Stow is 80% lighter than a typical hard bottle; Stow 1L is 50% lighter. The Mountain Stow is the better choice for minimalist or fastpacking setups.
• Packability: Both roll up when empty, but the Mountain Stow's smaller size lets it fit in places the 1L cannot, like a small hip belt pocket or a running short pocket.
• Valve and cap: Both have a spill-proof high-flow nozzle. The Stow 1L adds a flip-top cap cover to keep the nozzle clean when stowed in a dusty pack. If you often toss your bottle loose in a pack, the Stow 1L's cap cover is a practical advantage.
