- Who it's for
- Runners using Salomon vests, particularly the ADV 12, where fit is the primary driver. Works for short runs and longer/hotter efforts when carrying extras in the back pockets for quick swaps.
- What people are saying
- Hosts are matter-of-fact — they use it because it fits their vest, not out of strong preference for the flask itself. The wide mouth gets a specific callout as a practical convenience for ice and electrolytes.
- Worth noting
- Notes are thin and vest-compatibility-focused; no durability, taste, or leak issues raised, but also no deep testing reported.

Hunter Tart, Ultra Runner/Trail Runner
Honestly a flask is a flask, but these fit well in the ADV 12 vest so it’s what I use. No problems with them. Nice wide mouth so you can easily get some ice in there or pour your electrolytes in without making a mess.

On longer or hotter runs, I carry 2 extra flasks in the back so I can quickly swap them out on the fly.
