An ultra-packable windproof vest developed for moderate protection and minimal bulk, updated with a rustle-free fit, increased breathability, and lighter materials.

The improved endurance gilets fit with a less rigid wind-blocking front panel and a highly elastic mesh rear panel, allows the vest to wrap the body for a rustle-free fit while also increasing cooling airflow. Updated armhole elastic reduces restriction and ensures no overlap with the MILLE GT C2 Jerseys seams, increasing comfort and freedom of movement while eliminating friction between layers. The ultralight, ultra-packable design stows in a pocket when not needed, and the new mesh back panel reduces weight to just 75g (size medium).
