If you're a fan of cot camping—or just enjoy a roomy home-away-from-home—you'll rest easy in the Big Agnes Bird Beak SL3 tent, a spacious, lightweight shelter for off-the-grid adventures.

  • Features

    • DAC exoskeleton pole system maximizes architectural strength and offers extensive livable space; spacious interior is ideal for cots or anyone wanting some extra elbow room
    • External pole structure allows poles and fly to be set up before clipping in the inner tent body to minimize bad-weather impact
    • Plastic clips attach the fly to the external pole set; side-release buckles connect the inner tent to the fly
    • Bird Beak SL3 can be set up as a double-wall, 3-season tent or as a sun, wind or rain shelter without the inner tent body
    • Ready-to-pitch design comes with precut guylines and tensioners attached to the fly; color-coded webbing and buckles make setup even easier
    • 6 lightweight aluminum hook stakes help secure your setup; reflective guylines and reflective webbing offer visibility for low-light conditions
    • Features 2 waterproof doors to fend off the elements; make your entryway bigger with an optional Big Agnes vestibule (sold separately)
    • Quick Stash door keeper on the tent body door makes stowing the unzipped door quick and easy
    • All seams taped with waterproof, solvent-free polyurethane tape without PVC or VOCs; taped seams seal out bad weather
    • 2 oversized fly vents offer increased airflow and reduced condensation
    • 4 interior mesh pockets and 4 ceiling pockets stash your essentials; media pockets located above sleeping area enable clean earbud cord routing from phones or other devices
    • Easy-grip zipper pulls offer comfort; multiple interior loops let you attach gear lofts or other accessories (not included)
    • To extend the life of your tent floor we recommend using a Big Agnes footprint (sold separately)
