In short
Good for
- Warm-weather hill walking and fast hiking, where Rab says it keeps you cool
- Sun cover on summer wild camps and as a light sleeping top
- Packing light: 116 g in size M
Strengths
- 116 g in size M, among the lightest long-sleeve tops in the guide
- Dryflo Air fabric built for airflow and fast drying, per Rab
- Odour-control treatment, per Rab
- Raglan sleeves and microactive seams, per Rab
Weaknesses
- 85 g/m² fabric scores low for warmth: not a cold-weather base layer
- No independent hands-on test found, so comfort, odour and durability are estimates, not reviewed scores
- Regular fit with room for airflow, so less skin contact than a close-fitting base layer
- Rab publishes no fibre percentages; Ultralight Outdoor Gear lists 100% polyester
- Replaces the earlier Sonic top, which had mesh zones and a chest zip, so older reviews do not apply
