We improved our endurance gilet’s fit with a less rigid wind-blocking front panel, a mesh rear panel, and highly elastic side panel inserts, allowing the vest to wrap the body’s contours for a rustle-free fit while also increasing cooling airflow. Updated armhole elastic reduces restriction and ensures no overlap with the UMA GT Jersey C2 EVO’s 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 56g (size x-small).
