Somethin’ Special
The R1 Air fabric is truly remarkable. It feels like cotton but behaves as the technical hollow fiber polyester material it is forged from. Pure luxury. The fit is perfect for me. Form fitting yet flexible to afford total freedom of movement. I have been surprised by the range of temperatures this garment can adapt to. I have worn this trail running over a light sun hoodie from 45 degrees down to 10 degrees Fahrenheit. Will go lower if worn as a mid layer under a shell. It breathes well, but is plenty warm in a decent breeze. Excels at wicking moisture, is warm when wet, but does take some time to dry.
