How about this for your trekking this summer? This is the "Bora" series, a renowned backpack from "Arc'teryx," which started by manufacturing climbing harnesses and is now famous for its urban use. The rain cover can be detached with a single touch and used as a waist pouch. Large backpacks often make it difficult to look up because they hit the back of the head, but the Bora 80 is equipped with a helmet cup, allowing you to look up without being obstructed by the backpack. The side pockets have bungee cords, allowing you to tighten the opening after putting in bottles or small items. In addition, the buckles on the waist harness and the stock holders, which are being omitted these days, show the meticulous attention to detail that is instantly recognizable as "Arc'teryx." Product Name: Bora 80 Size: M/M Manufacturer: Arc'teryx Condition: The inner pocket that was heat-sealed to the kangaroo pocket (front pocket) is missing. Other than that, the highly weather-resistant fabric still has its firmness, and there are no noticeable scratches or stains. (Please judge from the images.) As this is a used item, there may be small scratches or oversights. Please refrain from purchasing if you are not familiar with flea markets or used items, or if you are overly sensitive. Also, in accordance with the flea market (recycling) spirit, the packaging will be simple, using recycled materials as much as possible, so please be aware of this beforehand. 【Please ask any questions before proceeding with the purchase.】 Related Manufacturers: MSR, Nemo, Petzl, Black Diamond, Mammut, Millet, Haglofs, Montbell, Patagonia, The North Face, Berghaus, Karrimor, Osprey, Deuter
