Two asymmetric vestibules,

The vestibules are created by the fly and offer practical storage options, such as keeping boots and shoes away from the main sleeping area. It’s important to note that the vestibules are not equal in size. One of the vestibules is relatively small, with an area of only 7 ft² (0.6 m²), offering limited space for storage. On the other hand, the second vestibule is significantly larger, with an area of 31 ft² (2.9 m²), providing ample room for storing larger items. This generous space allows you to keep your gear organized and easily accessible during your outdoor adventures.
The design of the fly incorporates strategically placed zippers that allow you to raise the vestibule flap and create an awning. This feature is particularly useful when you want to enjoy the outdoors without being fully exposed to the elements.
