Of all the bodyInsulators, the Assos SS.skinFoil_spring Base layer is perhaps the most versatile. Of course, Assos has specifically tailored each of their seven skinFoils to the climatic conditions you’re likely to find throughout the four seasons. But with its short sleeves and mid-weight insulation, the skinFoil_spring can be creatively paired with a summer jersey on cool June mornings or the intermediate jersey, with arm protectors underneath on windy October afternoons.
                  
As with all the skinFoil base layers, the key to their effectiveness, and seasonal appropriateness, lies in how the technicians at Assos have blended the polypropylene fibers. For the spring version, they use a relatively light mix that is focused on wicking the moisture away from your torso. The bodyMap method of varying the thickness, structure and elasticity depending on the needs of a particular part of your body proves to be effective when you see that, for instance, the shoulders have slightly more fabric and more elasticity to keep you warm while making sure you have a full range of movements, which will be so important when you need to reach back to your middle pocket searching for that hidden gel pack.
 
The use of a tubular weaving machine keeps the base layer comfortably seamless while the elastane used in the fiber mix provide a gentle compression that prevent the skinFoil_spring from bagging out with use. The Assos SS.skinFoil_spring Base layer will enhance your comfort throughout those hard to dress for spring rides where the weather could swing from sun to wind to rain in the span of a few kilometers.
