What Our Gearhead(R) Experts Are Saying: "I always bring the HD Annex when car camping. It turns my SkyRise into a full-on basecamp-great for changing, storing gear, or hiding from bad weather. Setup is quick, and it stays put even when the wind picks up."We love how the SkyRise HD Annex transforms our rooftop tent setup into a multi-functional campsite base. Whether it's serving as a mudroom, gear closet, cozy breakfast nook, or just a place to change after a long ride or paddle, this waterproof extension adds comfort and space without the hassle of a full tent. Yakima built the HD Annex with durable 210D ripstop nylon and a full PU waterproof coating. It installs easily below the tent's floor using the SideTrack system and a simple extension hoop. Zippered mesh windows bring in a breeze, and the included stakes and attachment hooks keep it rock solid when the weather shifts. With its tall ceiling and easy ladder access, it's like your own private wing off the main tent.
