Unhappy with the Sierra Design’s Flashlight as a winter tent in snow I purchased a Chouinard Pyramid tent  in 1985. Unable to afford a true 4 season double-walled tent, the Chouinard appealed to me because of its

• Price
• Light weight (2 lbs 9 oz without poles and stakes)
• Stability in poor weather
• Large interior area

What did not appeal to me after using it was

• Condensation in cold weather
• A pole in the middle that forced me to sleep on either side

But I used it for many years on many trips. However on most 3 season trips I reverted to my tried and true tarp, which was lighter and could be pitched in many configurations.

Today many ultralight shelters use a pyramid or modified pyramid shape, and with newer lightweight materials are super light and stable.
