The Assos LS. skinFoilwinterPlus Base Layer was constructed to be the ultimate long sleeve core protection for cold weather winter cycling. As with the other six base layers in Assos' new skinFoil line, the LS. skinFoilwinterPlus Base Layer has abandoned the pricey, multiple pre shaped panels of the past. Instead, the Swiss apparel designers took the approach of employing a less expensive, less restrictive, and more comfortable tubular construction. What this really means is that with the new skinFoil yarns, the LS. skinFoilwinterPlus Base Layer ensures that you'll remain comfortable and dry out on the frigid roads this winter. Assos' new skinFoil yarns are integral to the functionality of the LS. skinFoilwinterPlus base layer. This material is a proprietary blend of polypropylene and polyester. Polypropylene and polyester are both polymers, meaning that they're both essentially plastics. However, where they differ is that polypropylene is hydrophobic to the point that it's unable to absorb water. And, as a result, it spreads moisture out over a larger surface area, which rapidly accelerates evaporation. So, in short, these fibers ensure that your torso and arms will remain dry. And when combined, the two fibers provide you with the ideal interface for interaction with either your jersey or jacket. This yarn blend also forms a highly elastic material that creates a push pull effect in order to hold your muscles in place as you ride. The fabric is also antistatic and antibacterial, and it's also been dermatologically tested and approved. This means that you'll remain comfortable, fresh, and, most importantly, dry underneath all of your outer layers. For this new collection of base layers, Assos decided to forgo any pre shaped paneling designs in favor of a seamless, tubular construction. The reasoning behind this is that you receive a pleasing, non restrictive level of fit. The fabric matrix is also spun, much like a sock, versus the standard flatbed knit tech...
