Montbell Ultralight Zelt Color: Green Purchased about 10 years ago. I don't remember using it, so I probably haven't. However, there's a chance I might have unfolded it outside once, so I've listed it as "Like New" just in case. A zelt is useful in emergencies or during breaks. Unlike a tent, it's compact. It's an item you'll want to have with you when hiking. Weight: 240g including the stuff sack.
