The ProtoLab Silk Shorts take Soar’s performance thinking and run it through a natural‑fibre lens—built from a silk‑blend race fabric engineered for three‑season running rather than everyday gym fare.

Silk’s thermoregulating and moisture‑buffering properties mean the fabric absorbs sweat without feeling damp, helping you stay balanced even over longer efforts. Cut with a relaxed 4″ inseam and flowing volume, they let the material move freely and preserve airflow without excess bulk. A no‑waistband construction reduces pressure around the midsection, and bonded seams with laser‑cut hems strip everything back to the essentials.
