The OneUp is SlingFin's all-around Alpine/Mountaineering tent featuring our patented, award-winning WebTruss™ Technology. It is eminently configurable for use as a double-wall basecamp tent, a single-wall mess tent or comm dome, or bomber high camp tent for 4+ people. 

It includes our hexagonal inner tent body, which sleeps 4+ people and features 4 windows/vents. For two people, you can purchase the OneUp Rectangular Body, which replaces the standard Hex body and provides ample living space for two, plus two cavernous freestanding vestibules.

Use it with just the fly as a shade structure, or add the footprint for a fully enclosed single-wall dome. Clip in the tent body to turn it into a 4-season expedition shelter. It's extremely strong, and lighter than other tents in its class for the space it provides. The flysheet is made of silicone-coated nylon, and 6 equal-length poles allow for a quick and easy setup.


  • Available in orange/gray
  • Snow flaps on fly can either be extended out or folded under and attached under the WebTruss™ to seal out spindrift
  • Numerous guy points
  • Reflective tape located at each sleeve opening of the WebTruss™ for easy setup
  • Flysheet can be rolled back to create a shade structure
  • Includes removable floor - allows for "mess tent" configuration
  • Kick stand vents on doors don't flap in winds
  • Zippered windows in tent body
  • Fly-only pitch option (OneUp can be used with or without a tent body)
  • Internal guyline compatible
  • Lots of interior pocket space
