Whether we're headed to the boulder field, our hometown crag, or the gym, we're loading our gear in the Black Diamond Crag 40L Backpack. The abrasion-resistant material can handle grating desert terrain and sharp wooded areas, as well as keep our nut tool from poking through on crack days. The front pocket secures our keys for the day and keeps our guidebook readily accessible, while the internal organizer makes our tape and balm easy to find.
