When your 3-person tent feels cramped with your climbing partners and all your gear, try out the FirstLight Tent Vestibule from Black Diamond to add 13 additional square feet to your alpine camp setup. Made with durable weather-resistant material, this vestibule not only adds space to keep gear organized, it also acts as a weather barrier to keep gear protected from the elements. When it's time to push further into the wilderness after that pre-dawn light, you'll have a spacious area to organize gear and prep for the expedition ahead.
