With plenty of room for the essentials and included hydration, the UltrAspire Plexus 2.0 waist pack lets you customize the gear carried for varying running adventures. Built-in compression means it carries well whether you have with a minimal load or a day's worth of gear.
The pack's adjustable, weight-distributing ErgoFit waist system provides a comfortable, bounce-free carry. Breathable webbing cushions the pack while allowing excess heat to dissipate, and soft foam on the back panel keeps the included UltraFlask 550 Hybrid bottle comfortable against your back. An integrated speed hook makes it quick and easy to put on and take off the pack. Dual-sided pull-forward adjustability covers a broad range of waist sizes.
The pack offers a full 4 liters of storage. The back panel houses the included 550ml flask, which is made of soft and squeezable food-grade LDPE. It's also odor and stain resistant. A zippered stretch mesh pocket on the back expands to hold snacks or gear. The front floating pocket has an additional zippered pocket that can hold a cell phone and other items, as well as elastic cord for lashing trekking poles or other gear (sold separately). When not in use, the cord can be tucked away for streamlined performance.
