Whereas the internal tent is technically freestanding, it is advisable to carry a minimum of 2 stakes if you wish to stake out the entrance vestibule and the rear of the rainfly for higher air flow (sorry there’s no again door.) I’d nonetheless advocate staking out the corners, however you don’t must in a pinch.Â

It’s additionally value noting that the Portal has a 2-sided silicone-impregnated flysheet as an alternative of a PU coating for higher sturdiness. That course of, which can be utilized by Hilleberg, ends in a stronger and extra sturdy rainfly. The identical is true of the ground which is a 20D Nylon Ripstop coated with polyethylene (PE).
