XL on cots is almost always extra long (78-82″) for tall folks like 6′4″+-widths hover around 25-30″ either way, so not a ton more comfy unless specified. It’ll squeeze into some 2P tents diagonally (check floor dims like 90×50″), but solo? Go 3P or tarp it to avoid cot-tent wrestling matches.
Lightweight picks under 5lbs packing tiny: Helinox Lite Cot XL (2.8lbs, 17×6×6″ pack) or Kammok Mantis (2.9lbs, 20×5×5″). Both crush it for back relief without killing your pack weight. Newbie pro tip: pair with a thin pad for insulation, or you’ll freeze your tush off. Happy trails!
