Choosing a four-season tent depends on balancing strength, space, and weight. Geodesic tents offer maximum stability in wind and snow, domes are easy to pitch and reliable for most winter treks, while tunnels provide roomy efficiency for longer journeys but need solid anchoring. Double walls give better storm security and ventilation, while single walls save weight for fast alpine pushes but risk more condensation. Strong fabrics and ample vestibule space are also essential for handling snow load and storing winter gear.
