View source for ASSOS skinFoil evo7 Base Layer System

The ASSOS skinFoil_evo7 series, released in early 2015, marked a complete renewal of the brand’s base-layer concept. It replaced the previous “interactiveBodyInsulator” range and introduced a unified family of garments engineered for all climaRanges, from midsummer to deep winter. Every skinFoil_evo7 garment was designed to act as the foundation of the ASSOS Layering System (ALS), directly against the skin.

== Concept and development ==
According to the 2015 ASSOS product descriptions (archived via the Wayback Machine), the skinFoil_evo7 line was developed to provide total body-temperature control and moisture management across the entire year. All versions shared the same tubular seamless construction and moisture-reactive fibers, differing only in thickness and sleeve length according to their climaRange. Each model was numbered by temperature zone (1.4 – 4.4) and identified by sleeve configuration.

== Construction and technology ==
* Seamless tubular knit for maximum elasticity and minimal seams  
* Body-mapped compression zones for moisture transport and temperature regulation  
* Polypropylene/nylon fiber blend engineered for rapid drying  
* Antibacterial treatment to prevent odor buildup  
* Open-mesh or denser weaves depending on the climaRange  
* Anatomically pre-shaped pattern for the riding position  

All garments carried climaRange identifiers on the chest (e.g. 1.4, 2.4, 3.4, 4.4) for quick selection according to temperature.

== Available models ==
=== NS.skinFoilSummer_evo7 (1.4 Summer) ===
Sleeveless version for hot and humid conditions above 23 °C. Extremely light open-mesh knit for maximum ventilation and sweat evacuation. Ideal under short-sleeve jerseys in mid- to high-summer riding.

* Product ID 534  
* Color : White / Natural fiber tone  
* Sizes : 0, I, II, III  

=== SS.skinFoilSummer_evo7 (1.4 Summer) ===
Short-sleeve summer base layer providing slightly more coverage for intense sun or variable heat. Combines ultra-light polypropylene yarns with a tighter body fit to enhance moisture transport.

* Product ID 535  
* Color : White / Natural  
* Sizes : 0, I, II, III  

=== SS.skinFoilSpring/Fall_evo7 (2.4 Spring/Fall) ===
Short-sleeve model for cool transitional weather (approx. 15–22 °C). The fabric density increases moderately to retain warmth without losing breathability.

* Product ID 536  
* Color : White / Natural  
* Sizes : 0, I, II, III  

=== LS.skinFoilSpring/Fall_evo7 (2.4 Spring/Fall) ===
Long-sleeve variant of the same climaRange for rides in early spring or late autumn. Offers lightweight insulation and active wicking for variable temperatures.

* Product ID 537  
* Color : White / Natural  
* Sizes : 0, I, II, III  

=== LS.skinFoilEarlyWinter_evo7 (3.4 Early Winter) ===
Mid-weight long-sleeve base layer for early-winter conditions (approx. 6–14 °C). Features denser knit zones on the chest and arms to provide insulation and moisture transfer during cold-weather efforts.

* Product ID 538  
* Color : White / Natural  
* Sizes : 0, I, II, III  

=== LS.skinFoilWinter_evo7 (4.4 Winter) ===
The warmest skinFoil version for deep-winter use below 6 °C. Combines the thickest polypropylene structure with an internal brushed texture to trap warm air while keeping the skin dry.

* Product ID 539  
* Color : White / Natural  
* Sizes : 0, I, II, III  

== Shared features ==
* Seamless tubular knitting eliminates chafing points.  
* Varying density zones accelerate moisture evaporation.  
* Ergonomic collar height optimized per climaRange.  
* Rapid-dry polypropylene fibers maintain stable micro-climate.  
* Each base layer is labeled with climaRange and evo7 identification.

== Position within the ASSOS lineup ==
The skinFoil_evo7 family replaced the older interactiveBodyInsulator range and set the foundation for the later '''skinLayer''' generation (introduced 2020). Its introduction aligned the base-layer design with the new S7 outerwear collection, creating a unified ALS ecosystem from next-to-skin to outer shell.

== Sizes ==
All models were available in sizes 0 / I / II / III.
