Our ultralight shelters shield you from the elements while minimizing the wear and tear of heavy pack weight. They start with ultralight fabrics - our tent bodies are high tenacity nylon, the floors are made of the same material in a heavier weight for added durability with minimal grams. Factory taped seams keep the elements outside. We also use the absolute lightest fasteners and zippers and your trekking poles do double duty holding them up. Practical for most three-season conditions, our shelters will protect you even in serious storms.
