Seral 7

The Seral 7 solves the problem every hip-pack rider knows: where to carry water without strapping on a full pack. Osprey built in a low-profile Hydraulics LS 1.5L reservoir with a magnetic bite valve that clips to the strap so it's always within reach, then wrapped the whole thing in a bike-specific airmesh hipbelt and a close-to-body AirScape backpanel with a center airflow channel to cut down on sweat.

At 518g total (382g without the bladder), it stays light on the hip through a half-day ride, and side compression plus dual hipbelt pockets and tuckaway front straps keep a spare layer or snacks secured without adding bulk.
