This is a small pack (7L:M size) of the representative model "TR" of THE NORTH FACE SUMMIT SERIES, which continues to evolve as a technical pack for full-scale trail races. The main fabric is 100 denier nylon, which is both durable and lightweight, and is combined with stretch fabric to ensure storage space and create a smart shape. The back is made of highly breathable, lightweight mesh treated with Polygiene, which has antibacterial and deodorizing properties using silver ions. In addition, three chest straps are placed on the shoulder area, including a movable upper strap, to improve fit and hold. The external stretch pockets, which have a storage capacity that exceeds the internal capacity, include not only visible storage pockets on the shoulders, but also a large pocket on the front of the pack, designed for convenience that can be operated without stopping. It has a cord-type stabilizer that allows you to compress the main body while carrying it on your back, and the fit can be adjusted according to the capacity of your luggage. Recommended for short to medium races that require rainwear and emergency kits.
