Thank you for viewing! I purchased this once, but I haven't had a chance to use it, so I'm putting it up for sale. Quoting the following: High-functionality x Japanese-style design for comfortable wear even for long periods This is the ultimate backpack developed specifically for bicycles. Ultra-lightweight at 560g with a 10-liter capacity. Designed for comfort even when worn for extended periods, it's recommended for various situations, from daily commutes and school trips to cycling. Breathability and Fit with Mesh Mesh belts are used for the shoulder harness and hip belt. In addition to being lightweight, the design ensures breathability in the areas that contact the body, with careful attention to detail to prevent heat buildup. Cushioned belts can feel cumbersome while riding, but mesh belts fit softly and comfortably, providing stress-free movement around the shoulders. Comfortable Heat Release for the Back By arranging pads in two vertical rows on the back, airflow is created between the back and the backpack. During riding, the airflow expels heat from the back upwards, preventing stuffiness and keeping you comfortable. Please experience this comfort for yourself. S-shaped Back Pad The mesh cover on the back pad further enhances breathability. The back pad has a gentle S-curve, which fits the spine and supports proper posture. - Brand: BIKOT - Colors: Navy, Orange, White - Design: Wave pattern inner - Material: Mesh back panel - Pockets: Front zipper pocket - Straps: Adjustable shoulder straps - Features: Ultra-lightweight design - Accessories: Waterproof cover
