GTO NS DermaSensor

Assos GTO NS DermaSensor

The Assos GTO NS DermaSensor is the brand's highest‑quality Base Layer for warm to hot conditions and relies on a true seamless construction. The 3D‑jacquard knitting technology produces a one‑piece garment that fits like a second skin and actively wicks moisture away from the skin. With regularFit, high elasticity and odor‑resistant fibers, this undershirt is ideal for long training rides and demanding climbs in Switzerland. The material mix of 45% Polyamide, 43% Polyester and 12% Elastane combines fast drying with lasting shape stability. The variant comes in the blackSeries and covers sizes 0 to III. Official manufacturer information also confirms the recommendation for use on warm and hot tours.

Technical Details and Functions

The DermaSensor textiles are produced using 3D‑Jacquard‑Warp‑Knit as a seamless one‑piece garment, eliminating multiple separate panels and potential friction points. This construction delivers exceptional softness, high breathability and consistent compression, so the undershirt effectively disappears between skin and jersey. The pronounced moisture management wicks sweat from the skin surface and supports active cooling under load and on hot sections. Raw‑Cut edges at the waist and arms reduce material bulk and make clean layering under close‑fitting jerseys easier. The optimized regularFit is designed for long summer trainings and remains stable even during position changes in the saddle. All information is based on official product specifications.

Use Cases and Benefits

The GTO NS DermaSensor shows its strengths on long summer rides, high‑alpine passes and fast training loops on the Swiss Plateau. Worn under lightweight MILLE GTO tops, it supports a dry microclimate and reduces friction under the jersey. Thanks to the active cooling, the body stays capable on climbs, while the fast drying on descents promotes a pleasant temperature feeling. The odor‑resistant fibers are practical for multi‑day stages or regular indoor sessions. The seamless construction keeps the layer discreet and comfortable even under tight‑cut jerseys. Assos explicitly recommends its use for warm to hot conditions in combination with summer equipment.

Practical Feedback from the Trade Press (on the Technology)

Trade tests of the DermaSensor line emphasize the virtually seamless workmanship, the enormous stretchability and the very precise fit – at the same time the high price is mentioned as a point of criticism. Even if the cited test deals with the long‑sleeve winter version, the statements on material quality and seamless manufacturing are transferable to the NS version. Such feedback confirms the positioning of the DermaSensor pieces as a technological leader within the Assos baselayer range. For buyers in Switzerland this means an uncompromisingly comfortable, but deliberately premium‑oriented product. This allows equipment to be curated specifically for performance and wear feel.

Size Selection and Layering Tips

For the optimal Next‑to‑Skin effect the undershirt should be chosen close to the body without constricting; the high elasticity helps to cover different body shapes. In combination with lightweight summer jerseys the layer develops its best moisture management, as evaporation at the fabric surface is promoted. In tricky weather situations in the Alps the NS layer can be combined with lightweight Shells without adding bulk – the Raw‑Cut edges facilitate clean layering. Indoor trainers benefit from the fast drying and reduced odor formation over multiple intervals. For multi‑day tours the layer is a practical base thanks to its low pack size and durable fiber structure. These notes complement the official usage recommendations and support a well‑founded size and set choice.
