The Tight 330 is engineered as a second skin for ultra-distance mountain efforts. Its proprietary TightPro120™ fabric prioritises total comfort over muscle compression, with an apparent elastic modulus of 0.054 N/% that ensures unrestricted freedom of movement. The Möbius Belt™ waistband, a genuine technical achievement with its 0.125 N/% modulus, delivers stable carrying and unprecedented load capacity for a tight of this weight. The 3D Shape™ construction slightly shifts the crotch seam forward to eliminate irritation in this high-friction zone, while the fabric's air permeability (918 L/m²/h at rest) can nearly double when stretched over the quadriceps.
