The Outwell Sky 4 is a three-room tunnel tent offering a balance of practical living space and two darkened sleeping compartments. When packed, it measures 67 x 27 x 27 cm, weighs 14.3 kg, and can be pitched in around 12 minutes using Duratec fibreglass poles (8.5–12.7mm in diameter). The Outtex 3000 Select polyester flysheet provides a 3000mm hydrostatic head rating, PFAS-free water repellency, and UPF 30+ sun protection. A sewn-in polyethylene groundsheet ensures full waterproof coverage across both bedrooms and the living area, preventing ground moisture from seeping in and eliminating the need for a separate footprint. At the front, the tent features a wide-opening entrance with a vertical wall design, providing generous headroom in the living space.
