I’ve often thought about getting a 1 man shack, but pushing 6’5″ and 245 with a Striker suit on, there just isn’t enough room in one to satisfy me. JMO
I am shorter than you but was 100LBS heavier last winter, I ran an Eskimo Wide one for four years with a striker suit on. Worth a look, Easy to flip when you wanna stand, and has enough room when you want to get out of the wind for a bit. not to mention, one of the lightest shacks Ive ever ran.
