>>866110>Are 4-season tents required in 20-30°F weather?What’s critically important with a tent is FULL FLY that completely covers the tent “body”.
Nylon is nylon, it don’t retain heat for shit (that’s what your sleeping bag is for) but a full fly does create a bit of an insulating layer of air between the fly and the tent, slowing down heat loss. Notice how much snow is on the near tent (with a fully fly) compared to the typical Wallmart tent in the background, with just a small bikini fly on top.
But your real issue is rain.
Nothing ruins a good time like being wet, so you want to keep rain away from the tent body or it will soak thru the tent walls and your sleeping bag will end up wet and a FULL FLY does just that.
