Icebreaker Siren Hipkini Donna Slip hipkini in lana merino nero

Most underwear is either soft but fragile, or durable but stifling. The Icebreaker Siren Hipkini resolves that tension with a corespun merino blend that wraps ultra-fine wool around a nylon core, delivering the next-to-skin luxury of natural fibre with the resilience to endure daily wear. This low-rise brief is built for women who refuse to compromise between comfort and longevity.

Highlights

• 83% Merino Wool, 12% Nylon, 5% LYCRA® for a soft, durable, stretchy fit
• 150 Lightweight fabric (150gm/m²) — perfect for all-season wear
• Natural odour resistance, so you can wear it longer between washes
• High breathability and moisture-wicking properties keep you dry
• Flatlock seams reduce chafing and increase comfort
• Gusseted design and soft elastic waistband for a flexible, low-rise fit
