This is the 3-season configuration of SlingFin's CrossBow 2 backpacking tent with a mesh inner tent body. The WebTruss can be set up using a top bow pole (included), vertical strut poles, or trekking poles. The CrossBow 2 tub footprint or Ripstop inner body can be added for fastpack (StormPak no tent body) or 4-season use. Great for 3-season use. Extremely versatile can be used in wide range of conditions spanning from a fastpack setup (no tent body) all the way to a 4-season setup (with Ripstop Nylon tent body).
