NEW GORUCK BULLET RUCK - CLASSIC - REFLECTIVE SPEARHEAD The 15L Bullet is a grab and go daypack. One day it’s a trip to the pool, the next you’re stuffing jackets and snacks into your backpack for a day hike. It also makes a solid pack to loan a friend who is new to rucking and thinks their cheap book bag will be just fine — which it will be, till it won’t. New Fabric next to your skin: 210D Cordura back panel and under shoulder straps — you can wear this with a tank top or even shirtless without friction burns no matter the weight in the Bullet. If you’re looking for ALL THE WEIGHT, go with a Rucker. If you want streamlined and highly packable, go with the 15L Bullet.
