What Our Gearhead(R) Experts Are Saying: "I used the Approach Annex on a recent desert road trip and it changed the game-way more room to change, stash gear, and even cook when the weather turned. It's super easy to set up and the roll-up doors make it feel like a shaded porch when we're just hanging out." The Thule Approach Annex transforms rooftop camping into a more spacious, versatile experience. Whether you're seeking cover from rain, sun, or bugs, or simply need more room to change, cook, or relax, this smartly designed add-on doubles your living space while maintaining the sleek functionality Thule is known for. With roll-up front and side doors, the annex easily converts into an open-air awning-perfect for sunny afternoons or breezy evenings. Adjustable height ensures a great fit across a wide range of vehicles, while mesh windows keep airflow moving and the bugs out. A removable tarpaulin floor keeps gear dry and your space clean, and a skylight adds brightness inside. Crafted from 100% recycled polyester, the Annex packs small, installs in three easy steps, and delivers big-time comfort at camp.
