The Space-O Singlet sits at the top of SATISFY apparel system, built for race conditions and high-output training where thermoregulation and weight both matter.
The defining feature is the Space-O fabric: a 73% nylon / 27% elastane micro jersey knitted and laser-perforated in Italy. The punch-out process removes small portions of fabric, leaving precision micro-holes throughout the weave. This reduces total garment weight and creates passive airflow that a solid knit can't replicate. At 75g it sits at the lighter end of the race-specific category. Four-way stretch follows movement without pulling, and flatlock seams keep friction off the skin at armholes and side panels.
A few details worth noting: four S-Pins are included for race bib attachment, designed to thread through the perforations cleanly without tearing. The care label is fully detachable from the outside, leaving nothing against the skin. Reflective branding is only visible in direct light at night.
Worth knowing before you buy: Space-O is built for heat and high effort. It handles hard use well, but isn't the right choice for daily training under a loaded vest.
