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.

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 66, and 6 equal-length poles allow for a quick and easy setup.


  • Available in orange/white or all orange
  • 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
