[25L + 10L Expandable, Lightweight 580g] In addition to the 25L main compartment, the roll-top compartment expands to an additional 10L. Despite its total capacity of approximately 35L, it weighs just 580g. Its lightweight yet large capacity makes it suitable for a wide range of activities, from day hikes to overnight mountain climbs. The sleek design, measuring 73 x 24 x 16cm, provides excellent balance when worn. [Waterproof and Durable] Main body: Made of 40D coated ripstop nylon. It offers excellent tear resistance and water repellency, making it resistant to sudden rain and branches while digging through thickets. Reinforced sections: Made of 210D ballistic nylon (a high-strength polyester blend) with breathable mesh for exceptional durability and breathability. It offers reliable performance even in harsh outdoor environments. [Comfortable Carrying] The backpack features a three-point adjustable suspension system (shoulder straps, chest strap, and hip belt). It fits snugly against the body, efficiently distributing the load and reducing shoulder strain by approximately 50%. The back panel is equipped with a highly breathable EVA cushion, which prevents stuffiness even when carried for long periods of time, ensuring a comfortable carrying experience. [Functionality Thoughtfully Designed Down to the Detail] This bag uses trusted components like a YKK double zipper and Duraflex buckles. External loops, D-rings, and side compression straps allow for easy attachment of poles and mats. It's packed with full-featured gear, including a large-capacity mesh pocket, bottle pockets on both sides, inner storage, an emergency whistle, and a removable EVA back panel. [Suitable for a variety of occasions] This bag is useful for a variety of purposes, including mountain climbing, trekking, and camping, as well as bikepacking, bicycle trips, festival participation, and even storing disaster preparedness supplies. It is lightweight and compact, making it easy to carry, and its simple, stylish design makes it suitable for everyday use as a bag for commuting to work or school.
