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.
Size vs weight trade-off
The Mountain Stow 350ml is 80% lighter than most hard bottles, making it nearly unnoticeable in a pocket or small pack. The Stow 1L, while still 50% lighter than most hard bottles, offers four times the capacity. The trade-off is clear: the Mountain Stow disappears into your gear, while the Stow 1L gives you enough water for a full day hike without the bulk of a rigid bottle.
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.
