A go-anywhere base layer top featuring icebreaker's most versatile 100% merino wool fabric, the 200 Sonebula Long Sleeve Crewe insulates, resists odours and provide incredible breathability for active pursuits in any weather conditions. The raglan sleeves and gusseted underarm construction offer improved range of motion, while flatlock stitching throughout provides chafe-free comfort.

Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fibre that naturally resists odours, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
