Contour™ Lumbar 1.5L

I took this on a hot trail ride and the lightweight design made it barely noticeable. The reservoir holds exactly enough water for my shorter laps without bouncing around.

The slim profile actually fits in my jersey pocket without bulging, which I didn't expect from a 1.5L reservoir. Stayed put on a bumpy descent and the bite valve never leaked. Exactly what I needed for shorter race days.

Took this on a 40-mile ride in 90-degree heat and barely noticed it bouncing around my waist. The 1.5L capacity is spot on for a couple bottles plus snacks, and the material feels rugged enough to survive getting tossed in the truck bed.
