With mesh walls for maximum ventilation, the Alps Mountaineering Zephyr 3-Person Tent lets in a breeze for added comfort when pitching camp in warmer climates. Lightweight, strong 7000 series aluminum poles support the mesh walls using pole clips for quick-snap assembly. Add on the 75-denier, 185T polyester fly with 1500mm coating and UV resistance for waterproof protection. Both the fly and the 75-denier, 185T poly taffeta floor with 3000mm coating feature factory-sealed seams for waterproof integrity.
