Using the Trango Crag 2.0 Pack is a breeze. First, put your shoes in the external mesh pouch so they can breathe between climbs. Keep your guidebook in the dedicated pocket for easy access without taking the pack off. When it's time to rack your gear, use the mini tarp to create a clean area. You can easily fit a rope bag inside thanks to the tapered shape. For trash, use the included 25 Access Fund wag bags. Store your sunglasses in the fleece - lined pocket in the hood. When carrying the pack, enjoy the comfort provided by the lighter, reinforced frame and redesigned padding. As for maintenance, make sure to clean the pack regularly. If there are any small tears, repair them promptly to keep the 1000 denier reinforced bottom and the rest of the pack in good condition. Also, keep it dry and store it in a cool place when not in use.
