Rab Men's Sonic Ultra Running T-shirt Beluga/Graphene (2026 Update)

When the pace picks up and the temperatures rise, the Rab Sonic Ultra Tee is built to keep you moving in complete comfort. Weighing just 106g (Size M), this ultra-lightweight mountain running tee delivers exceptional breathability and moisture management, making it ideal for fast-paced trail runs, mountain races, and high-output adventures.

Constructed from 85gsm Dryflo™ Air single jersey fabric, the Sonic Ultra combines rapid moisture-wicking performance with advanced airflow technology to keep you cool and dry on demanding climbs and technical terrain. Laser-cut ventilation under the arms and at the back of the neck enhances airflow where you need it most, while an odour control treatment helps the fabric stay fresher for longer.

The slim fit is designed to move with you without adding bulk, featuring a split hem for increased freedom of movement. Microactive seams provide all-day comfort against the skin, while seamless outer sleeve edges help reduce chafing on longer runs. Finished with reflective Rab branding for improved visibility in low-light conditions, the Sonic Ultra is equally suited to wearing on its own in warm conditions or as a lightweight base layer when heading to higher, more exposed ground.
