Advanced Projects® is our series of products designed and developed with the most advanced textile and construction technologies available in the world.

Advanced Projects Seamless Base Layers represent the future of next-to-skin technology. They are designed to perform at an elite level for a wide range of activities including cycling, running, hiking, and climbing. They keep you cool when you’re warm and warm when you’re cool. They breathe exceptionally well to keep you from sweating; and, if you do sweat or if it rains, they won’t bag out and will dry quickly.

The base layer fabric is a soft lightweight knit with extreme 4-way stretch that incorporates 37.5® vapor management technology. 37.5 technology was recently included in a comparison study performed at the University of Colorado in Boulder and published in the International Journal of Sports Medicine. In that study, this technology was found to increase performance at peak exertion by 26% over traditional performance wicking apparel.

To our knowledge, there is no other available technology that performs as well as 37.5 for high-activity applications.

Seamless construction enables the torso section of the base layer to be knit in one piece minimizing bulk and the potential for friction spots. It also allows for multiple fabric thicknesses to be incorporated into the garment without the need for sewn panels so that insulation and breathability can be optimized. In addition, seamless construction allows size and care instructions to be knit directly into the garment eliminating the need for scratchy tags or heat transfer labels.
