For two months, the Peak Design Outdoor 45L Pack sat on my shelf. Its design intimidated me: no traditional clips, a roll-top, and an array of dangling cords. I’ve packed hundreds of bags, but I couldn’t figure out where to start with this one. I shelved it for "later," waiting for the right opportunity. That opportunity finally arrived. I was heading to Loreto, Baja California Sur, for a quick trip to photograph whales. Carry-on only, no room for error.
