Don’t bake in your tent! Stay cool and sleep in. Patent pending, heat reflective, light blocking, and designed for wind & dust. Updated design based on customer feedback from the last 5 years. Stronger interior seams, re-enforced stake out loops on the vestibules, color coded top pole, internal facing door zippers to help increase zipper life, stronger stakes, re-engineered seam sealing and a new easier to pack carry bag. The core technology remains; but we have made numerous updates to make the tent even better.
