Womens Merino 150 Siren Bikini
Description
Icebreaker Merino 150 Siren Bikini is a women’s merino underwear essential for travel, hiking and daily wear, using 150 g/m² corespun wool for breathable, odour resistant, quick drying comfort. Designed for next-to-skin softness with long lasting durability, it balances natural performance with a flattering, low profile fit that disappears under layers.
The Siren Bikini uses Icebreaker’s Corespun construction where superfine merino fibres are wrapped around a strong nylon core with a touch of elastane. The result is a light and resilient fabric that regulates temperature, manages moisture and resists odour on multi-day trips. A lined gusset enhances hygiene and comfort, while flatlock seams and a soft elastic waistband minimise chafe under packs and harnesses. Whether you are fastpacking, trekking or living out of a carry-on, this easy care brief keeps you fresh and comfortable with less to pack.
