Best Alternatives to Salomon Soft Flask 500 ml

Salomon Soft Flask 500 is the 38g standard-valve 500 ml vest flask — vest-pocket size, not Speed, not a handheld. Leave it when high-flow Speed sipping is the gap, when you need a Nathan 18 oz spare, a UD Body Bottle last, or a strapped ExoShot handheld. Stay when a simple 500 ml Salomon sleeve flask is the spare you actually refill.
