OverviewDermaSensor is ASSOS's 3D-jacquard base-layer textile — a knit construction (not a membrane) with a surface pattern that channels sweat off the skin and distributes it for faster evaporation. GTO-tier grade, calibrated for the Mille GTO long-ride pace. GTO NS is summer; GTO Spring-Fall LS is 2/3; GTO Winter LS is the 3/3 grade with brushed interior. This is the GTO NS DermaSensor — the summer-grade GTO-tier sleeveless base layer with 3D-jacquard construction.DetailsBest forGTO-tier long endurance rides where sweat management is the limiterRiders who want ASSOS's 3D-jacquard surface distribution patternWinter LS for deep-winter endurance layering (brushed interior)Pairing with a MILLE GTO jersey or bib for the full GTO system SpecsConstruction: 3D-jacquard knit (not a membrane)Surface pattern: channels sweat for faster evaporationGrade: GTO-tier — calibrated for long-ride endurance paceTemperature grades: GTO NS (summer) / GTO Spring-Fall LS (2/3) / GTO Winter LS (3/3)Winter LS: brushed interior for deep-winter endurance layeringCompatibility: pairs with the MILLE GTO bib and jerseyColourway: BlackSizes: 0 · I · II · IIIMaterials & CareCareMachine wash cold on delicates with ASSOS Active Wear Cleanser or pH-neutral detergent.
