The Nanook XL is a portable, flip-over fish house that allows two anglers to fish comfortably side-by-side. Or for larger guys, the Nanook XL works as a great one-person shelter. And with our exclusive Symmetry Door System, anglers can get in and out of the shelter with ease. This model has been one of Clam’s most popular fish houses over the years. This lightweight shelter cuts through the snow and glides effortlessly across the ice to set you on top of the perfect spot.
