SkyFlask™ Speed 350ml

The thumb loop is a game-changer for longer runs — my grip stays relaxed and I don’t feel the flask shifting at all. It’s so light I almost forget it’s in my hand, which is exactly what I wanted for training.

I was skeptical about the thumb loop at first, but it really does let me relax my grip during long runs without the flask slipping. The 350ml size is just right for a quick training session, and it's surprisingly easy to clean.

The thumb loop is a game-changer—my grip stays relaxed the whole run, and I don't feel like I'm white-knuckling a bottle anymore. It's light enough that I forget it's there, which is exactly what I wanted for speed work.
