I IMG_20150721_164047_159.jpghave a very nice Cuben Lightheart Solo with silnylon floor that I'm looking to trade for a Zpacks Duplex. I love the Lightheart but now my puppy is growing up to be a large dog it is a little cramped. It weighs 21 ounces and is like new condition. Here is pic from a recent trip. As you can see it has the awning which is really nice and sil strips on the floor
