Yeti Crossroads 35L Backpack - Alpine Brown The Crossroads 35L Backpack is a high-capacity vault for your clothes, snacks, and travel gear. This is the one-bagger you'll depend on through long workdays that demand a lot of gear, and weekend trips where you'd prefer to skip baggage claim. A clamshell opening combines the 180 degree fold-open packing convenience of a suitcase with the portable ease of a backpack. When travel calls for the addition of roller luggage, secure your backpack to the top of your bag with the luggage pass-thru sleeve. Plus, the water and abrasion-resistant TuffSkin Nylon lets you go further than any backpack you've had before.
