Running vest backpack Guto UltraFun black size S – lightweight hydration and storage vest

The Guto UltraFun running vest backpack in black, size S is a lightweight vest-style pack designed to carry hydration and small essentials on short to mid-distance runs. Its compact profile combines a close-fitting vest with backpack-style storage to keep bottles, snacks, a phone and keys accessible without restricting movement. The design balances low weight and secure fit for both road and trail running where fast access to supplies and stable load carriage are important.

Advantages

The vest provides a snug, body-hugging fit that reduces bouncing and friction during dynamic movement. Multiple front and rear pockets allow organized storage of soft bottles, nutrition and a smartphone while maintaining low overall volume. Breathable, lightweight materials improve comfort in warm conditions, and adjustable straps enable a personalized fit for size S. The streamlined silhouette minimizes snagging on branches and gear while running on technical trails.
