The Arc'teryx Sebring 25 Backpack is excellent for any day activity whether you're hiking, climbing, traveling, trekking, or simply heading to school or work. Arc'teryx made this bag primarily out of N630p HT nylon for extreme durability, and the back panel consists of Spacermesh for breathability, HDPE for support, and EV50 foam for comfort. The padded shoulder straps are super comfortable, and you can remove or adjust the sternum strap for an ideal fit. The main compartment completely opens out so you can reach anything in your bag with ease. There's a sleeve for for a hydration bladder and two pockets for over sized water bottles. Arc'teryx also added two external pockets with organization slots for your work or school papers, and the internal security pocket has a clip to keep your keys safe.
