Included is a storm door, plus lots of ventilation from the top. Plus there is a zip-out vestibule that helps cut down weight, which in turn provides additional space for gear storage. Also featured are double-layered corners, a bathtub-like floor, and double-taped seams that keep the Heka protected from wind and rain. Additionally, there’s a 2-way compression with V-shape carry bag for easy transportation and setup.
