How it feels during movement

The 4‑way stretch mesh flexes with your body, expanding to carry a heavier load or compressing when you’re light on essentials. The MaxO2 sternum system helps keep breathing unimpeded while the pack remains stable against your torso, helping you stay steady through turns and sprints. A thoughtful shock cord offers controlled stretch for a responsive, rebound feel as you pick up tempo.

Designed for runners who want reliable comfort, the Spry Vest blends a minimalist profile with a secure, balanced ride. Its light frame and breathable fabric are intended to reduce chafing and heat buildup, so you can concentrate on pace rather than pack management.

Storage, access, and hydration

• Reservoir compatibility supports up to a 1 liter bottle (not included), enabling convenient on-the-go hydration
• Compact design helps keep keys, nutrition, and a compact layer within easy reach

The total capacity of 3.5 liters is designed to accommodate essentials without turning the vest into a burden. The combination of a light weight and expandable mesh makes it a versatile option for training runs, tempo efforts, and early morning adventures where every gram matters.

Who this is for

Runners seeking a fast, unobtrusive carry will appreciate the Spry Vest, especially those who value a breathable fit and quick-access pockets.

Keep in mind that reservoir inclusion is not guaranteed and may vary by package.
