What Bibler says
The four-season Ahwahnee is the most versatile Bibler tent with two mesh-covered full-size side doors that can be opened all the way up for easy exit/entry and excellent ventilation. With wide awnings over each, the doors are protected from rain and can be left partially open to vent. The incredibly strong and lightweight Ahwahnee is built with a waterproof and breathable ToddTex canopy and a polyurethane-laminated nylon floor and all the seams are factory taped. With two aluminum poles that fit inside the tent, it’s easy to pitch and quiet in high winds. For interior organization, the Ahwahnee has two interior net pockets. Optional vestibules that work on either side of the tent are available.
What I'll sayBeing a single skin tent it is necessary to open one of the doors to fit the poles inside, this can be a problem when it's raining and the inside of the tent gets wet even before it is fully set up.
As far as breathability goes, this tent is excellent. I've only had condensation one time out of the 100+ nights I've slept in it.
Be careful to make sure the poles are locked in the small metal holders in the corners when you are setting it up. I have twice punctured the floor of the tent, when setting it up quickly.
