I have camped in my Marmot Swallow numerous times. From near 100 degree heat to near zero degree cold, in sun and in rain. I have to say this is a superb tent. With all of the venting in the tent, I get almost 0 condensation in freezing weather. With the rain, I never get a drop in the tent, and in the heat, I take the rain-fly off, open up all of the doors and vents and it is as cool as can be. Add to that, it is very roomy and easy to set up. It's a tad on the heavy side, but I backpack with it and will very gladly accept the couple of extra lbs. for the versatility and reliabilty that it provides for varying conditions. I highly recommend!
