I am really happy with this tent. The design, craftsmanship, materials and quality all exceeded my expectations for the price. My Zephyr 1's maiden voyage was baptism by snow and wind on Mt. Adams in Wa. St. on October 2nd. This is a 3 season tent but it will keep you warm and dry if you use a well designed insulated sleeping mat like the Exped downmats combined with a good sleeping bag. We "guestimated" the windes at 20-40mph and tempuratures dipped into the low 20's F. I secured the tent with the supplied guy lines and aluminum stakes before turning in for the night and I was glad I took the extra steps. No one really wants to see the wind blowing snow sideways when we go camping. I highly recommend getting the footprint. Search for "floor saver" when trying to find the footprint. The footprint did its job well because the ground did freeze that night and I know it provided an insulating layer as well as protect the floor of the tent. I also liked that you can clip the urethane-coated polyester fly to the floor saver at all four corners.
