If you like room to move inside your shelter, look elsewhere. We offer a separate clinic on bivy shelters for your consideration. Sleep screens and tarp tents are ultralight shelter options. Sleep screens, including screen houses, are useful in warm conditions and offer mesh coverings, some fully enclosed, some not, to keep occupants shielded from bugs, but not rain. Tarp tents offer minimalist shelter, at a minimal weight, for three-season usage.
Domes avoid flat spots and shed snow more easily.
They stand strong in the wind and provide generous interior headroom. Also called hoop tents, these models use fewer poles, less fabric and often have wedge-like shapes. Their rainflies, which lie flatter, can collect snow. A heavy snow load could flatten them. You can also easily shake it out before you disassemble and pack it.
