Rab Men's Sonic Hoody

The layer that lives between a tee and a midlayer on high output days. When it's too cool to start in just a base but too warm to commit to a full midlayer, the Sonic Hoody fills that gap without slowing you down.

Highlights

• Dryflo Air single jersey fabric — A highly breathable, lightweight fabric at 85gsm that wicks sweat rapidly and maximizes airflow during hard efforts. Responsive to output so it keeps up with you on fast moving objectives rather than holding heat when you don't need it.
• Odour control treatment — Stays fresh over multiple days without washing. A practical advantage on multi-day trips or back to back trail days where you're not doing laundry between efforts.
• Wrap-style hood — Fits close to the head without bulk or shifting. When the wind picks up on an exposed ridge or summit, it adds meaningful warmth without requiring a separate layer.
• Underarm gussets — Full arm lift for reaching holds on climbs and scrambles without the fabric pulling or restricting overhead movement. A technical detail that shows up where it counts.
• Hidden stretch thumb loops — Keep sleeves in place under gloves or during dynamic movement without bunching up at the wrist.
• Microactive seams — Flat, comfortable construction that sits cleanly against the skin under a harness, pack straps, or additional layers without creating pressure points.
• 4.4 ounce weight — Light enough to justify carrying as a standalone piece even on minimal kit days where every ounce is evaluated.

Best for

Trail runners, alpine climbers, and fast hikers who need a lightweight, breathable hoody for cool morning starts and high output efforts where a heavier midlayer would be too much. A strong single layer option for shoulder season and variable conditions.
