MSR's Backcountry Barn shelter's single-wall construction affords amazingly spacious protection for four people in a relatively small package. Its easy-pitching, hooped design offers standing head clearance from end-to-end for most, and steep sidewalls expand livable space to its maximum potential. An included, detachable floor lets you adapt the interior for anything from covering a picnic table or storing group gear, to sleeping quarters or a remote race check-point/aid station.
