The Black Diamond I Tent is ultralight, super strong, and built with waterproof breathable ToddTex single wall fabric. The poles are set up internally, making this tent ideal for setting up in stormy conditions. Just crawl inside and pop it open from there. This two person shelter was designed with narrower dimensions for the extreme mountain climber to pitch on ledges, yet any four season outdoorsman or woman will appreciate the thoughtful integration of bombproof features into this tent that make it ideal for light and fast trips to altitude. Fully taped seams ensure that you won't wake up to one corner of the tent swiftly becoming a soggy lake for your sleeping bag. On warmer days, or just any time you need to deal with condensation, two zippered vents at the apex allow for airflow and comfort.
