ACT BioPerf Long Sleeve T-Shirt - Our FAQs

1. How does the thumb loop improve the running experience?
   The thumb loops keep the sleeves extended over the backs of your hands, providing extra warmth in cool air and ensuring the sleeves do not ride up when you are sprinting or using trekking poles.

2. Is this long sleeve too warm for summer use?
   No, the BioPerf fabric is exceptionally thin and breathable. It is designed to wick sweat and provide sun protection without trapping excessive heat, making it versatile for year round use.

3. What makes castor bean nylon a "sustainable performance" fabric?
   Unlike standard nylon which is petroleum based, this fabric comes from a renewable plant source. It requires less energy to produce and results in 59% lower carbon emissions while offering superior softness.

4. Can I wear this as a base layer?
   Absolutely. The silk like softness and flat seams make it an ideal primary layer underneath a windproof shell or waterproof jacket during winter training.
