These step up from the standard Sorpasso with high-tech extra warmth exactly where you need it.
All of the fabrics are exceptionally soft, stretchy and warm, with Nano Flex 3G covering most of the body for some thermal gain and flexible mild wind and water protection. The addition is application of GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fleece-backed fabric panel on upper front and thighs for extra warmth, and you'll be surprised how much of a difference this makes, as the superior windblocking textile refuses to let air in which keeps you warmer, plus the gain from the added fleece. Your groin area is kept safe and you don't waste muscle energy to keep the energy producing thighs warm. The fabric also has high a breathability rate so when you are at your limit, you stay as dry and comfortable as possible.
In another upgrade from the standard version, the Sorpasso RoS Wind upgrades the rear panels to Nano Flex 3G, from Nano Flex Xtra Dry, giving the garment a more universal feel and protection level. The ankles bring forward the rear opening YKK Camlock zippers for easy on and off, and reflective inserts that are placed along both zipper for low-light visibility. The designers also feature one of their most comfortable seat pads, the Progretto X2 Air, which has proven to be a perfect design for comfort and protection for both cool weather and long hours in the saddle. it conforms to and moves with the body, reducing friction, without bunching. The upper features a soft and 2-way stretch bib and lie-flat elastic strap construction that offers lightweight support and great fit while wicking moisture away from the entire back zone. The cut is fluid and anatomic, with specific shaping at the hips and knees for freedom of movement and supportive fit.
