problem i have with true 4 season tents is they are hot as balls in the summer.
A good 4 season is not good in the summer. Ya need a summer tent and a winter tent.
my 3 season + is even too hot with the fly off.
Look on craigs. there is always some Boulderite selling off a good 4 season exp tent for used 1-3x when they realized they aren't climbing mckinely and are going back to illinois.
