At the start of each month, I'm going to take a moment to write about a product that I use on EVERY climbing trip. Something that gets packed EVERY time, no matter what. These are products that I feel help me perform my best, make my life easier, or are just plain cool. With that said, here is my choice for April: The Eiger 35

I love this pack because, as a climber, it is the perfect size. With a volume of 35 liters, I can fit a 60 meter rope, a full rack of 14 or so cams, half a dozen quickdraws, several pairs of climbing shoes, chalk bag, harness, food, water, and a few extra layers of clothing. I can even lash a thermarest and a lightweight tent to the sides of the pack. No problem. I've used it to approach Half Dome with 35 pounds of stuff as well as for day trips looking for new climbs. The compression molded back panel molds to fit your back perfectly while the S-curved shoulder straps and the thick waist belt help distribute the load however you like. Additionally, the Eiger 35 has a hydration pocket for your water bladder, stash pockets in the waist strap, a solid closure system for the lid, and above all, its COMFORTABLE. It's the only pack I own for all of these reasons. If I'm packing lighter, I'm wearing a crash pad, otherwise, it's the Eiger 35.
