The Eureka! Grand Manan incorporates a new concept in tent design providing moreuseable floor space. The lower portion (the bottom 12") of the walls is straight, eliminating the unusable space where the walls meet with the floor, maximizing the floor area. Additionally, the sides of the fly roll up from the ground for optimal airflow through the tent. The Grand Manan is a dome tent withfiberglass poles and two D-shaped doors, and has outdoor vestibules for shoe andgear storage.
