Review: Perfekt für schnelle Trailläufer - Ich nutze die Flasks bei Trailrunning Wettkämpfen, bei denen es an den Verpflegungsstellen schnell gehen muss. Durch den Clip-Verschluss fällt das auf und zu schrauben weg und ermöglicht dadurch ein deutlich schnelleres nachfüllen. Die Flasche hält dicht und läuft auch in einem Laufrucksack nicht aus. Die Flasks haben ähnliche Maße wie die Salomon Flasks und passen in alle Salomon Rucksäcke, andere Laufrucksäcke weiß ich nicht genau. Natürlich ist die Flask nicht nur für schnelle/ambitionierte Läufer geeignet sondern auch für Leute die es gerne einfach haben. Jedoch würde ich schon sagen, dass der Hauptvorteil beim schnellen nachfüllen liegt.
Review: Works perfectly - Great for long runs. Doesn't leak and super easy to refill

### ⭐⭐⭐⭐⭐ Works perfectly
*by B***G on 16 July 2025*

Great for long runs. Doesn't leak and super easy to refill

### ⭐⭐⭐⭐⭐ Backpacking
*by D***C on 17 August 2023*

Use it in the shoulder pouches of an Atompacks 55 liter pack. Easy hydration on the move without having to pause to reach back for a bottle in a side pocket, which ensures constant and consistent replenishing of fluids. Large opening works well for pouring electrolyte powders. Simple to refill with a BeFree water filter. Recommend for simplicity on the trail.
