Columbia OMNI-SHIELD waterproof chalk-colored Columbia Castle Rock 2 15L backpack. Simple and easy-to-use size. The back and shoulder straps are also cushioned, making it less likely to hurt your shoulders even when carrying heavy loads or using it for long periods. It has ventilation grooves on the back for comfort. Used once for hiking, selling because I'm upgrading to a larger capacity one. There is a small scratch as shown in the third photo. ・ Actual size: Capacity 15 liters / Height 40cm / Width 26cm / Depth 15cm ・ Columbia's unique water-repellent function "Omni-Shield" ・ Columbia's classic backpack, perfect for hiking ・ Form that fits women easily ・ High-strength nylon material ・ Open pocket inside the main compartment ・ Velcro pocket and tape loop inside the second compartment ・ Well-ventilated back structure with a ventilation path in the center ・ Reflector pull cord for night visibility ・ Rain cover with windproof straps ・ Sides: Mesh pockets x2 ・ Front: Zipper pocket x1 ・ Front: Velcro & mesh pocket inside the second compartment ・ Main room: Open pocket x1 [Functions] ・ Well-ventilated back structure with a ventilation path in the center ・ Rain cover with windproof cord included (zipper pocket for storage on the bottom) ・ Chest harness included ・ Weight: Approximately 540g #Outdoor #Camping #Trekking #Cycling #Jogging #Patagonia #The North Face #LLBean #Montbell
