Overview
Breathable running vest with Crux reservoir compatibility for long trail days.
Kitletics notes particular strengths around strong bladder ecosystem and ventilated harness feel.
- Strong bladder ecosystem
- Ventilated harness feel
Kitletics Review · 8.1 Good
CamelBak Zephyr is a running pack / vest (10; 0 flasks). Breathable running vest with Crux reservoir compatibility for long trail days. I'd shortlist it for strong bladder ecosystem. The trade-off is reservoir cleaning overhead vs soft flasks — Nathan VaporAir 2 is the cleaner compare when that is most of your week. It fits buyers who actually need a running pack / vest (10; 0 flasks), not a one-product rotation.
