Overview
Long rides in low light call for a pack that carries water without much bulk. This one pairs a Crux reservoir with a breathable air mesh back panel, ventilated harness and reflective accents.
The reservoir has an ergonomic handle for quick refills and a leak-preventing on/off lever. A zippered pocket holds keys, tools or small personal items. Storage stays minimal by design.
Who it's for
Riders after a streamlined pack for water on long rides are the match. Anyone hauling clothing or bulky tools needs a larger bag.
Pros and cons
- Breathable air mesh back panel
- Quick refill handle
- Small cargo space
- Only two pockets
Performance notes
The mesh back panel and ventilated harness let air move across the rider's back. The Crux reservoir is shaped to deliver more water per sip, and the on/off lever closes the line when it is not in use.
