An ultra-lightweight stretch backpack suitable for long-distance trail running, city running, and ultralight trekking. The body uses stretchy nylon material, allowing for efficient compression regardless of the size of the load. The "Speed Fit" system, which fits the pack snugly to the body simply by pulling the straps on the bottom, maintains a clean design while preventing the pack from swaying. Quick-drying mesh material is used on the back and shoulder straps for comfort during exercise. Pole holders are provided on the front and back and can be removed as needed. Emergency whistles, flask bottles, and stretch pockets equipped on the shoulder and waist harness are also attractive features. ▼ Color 8755 ▼ Size 15L ▼ Weight 360g ▼ Capacity 15 liters ▼ Material N/70D 210T TAFFETA R/S SILICONE COATING POLYAMIDE STRECH PEACH SPAN ▼ Features ・Body made of stretchy material ・Shoulder harness with stretch pockets that can hold 500ml soft flask bottles ・Zip waist pockets on both sides ・Pole holders on the front and back ・Emergency whistle ・Speed Fit patented speed compression system ▼ Back Length 43cm
