The uppers are made from abrasion resistant, breathable, water repellent mesh and the lining uses the Gore-Tex Extended Comfort membrane to guarantee water resistance and breathability. The integrated lacing system uses a webbing stitched to the inner stretch fabric while the high frequency reinforcements remain on the external mesh fabric: this allows for an optimal distribution of foot tension and keeps the foot in check without compromising overall comfort. Ultra Raptor GTX brings together the advantages, in terms of performance, of a snug fit construction, to the superior comfort levels of wide fit models. The result is a product that can be worn for many consecutive hours and for endurance on any type of off road terrain both in the winter or in conditions of extreme humidity, thanks to the Gore Tex water proof lining.
