    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.

    Evan Watkins's review

    With Salomon specifically, the wide opening compared to the size of the flask makes these super easy to clean, which is something I really appreciate with how often I use them.

    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.
