Tempo Pro 525ml

The sandal-cut strap is the reason I stopped using my old bottle — it actually lets air get to my wrist instead of trapping sweat underneath. Fits my hand well at 525ml and never feels like it's going to slip mid-swing.

I was a bit skeptical about the strap design, but it actually stays put even when I’m running. The bottle fits nicely in my palm, and the airflow around my wrist is a nice bonus. Just wish it came in a slightly larger size.

The sandal-cut strap really does keep my wrist from getting sweaty during longer carries. Only gripe is the lid takes a bit of force to click shut, but it hasn't leaked yet.
