heading to Idaho for general mule deer around Oct 12th through whenever I've had enough. Back packing in (hopefully 5 miles) and planning on setting up camp around 7000' or so. Have a Nemo Sonic 0° bag and a insulated Tensor pad. Now I'm looking at tents. Have some experience winter camping in the midwest, but know the mountains are a different experience. Knowing that im a warm sleeper, is there any reason to consider a 4 season tent?
