Women’s Merino 150 Siren Hipkini

Meet the Women's Merino 150 Siren Hipkini by Icebreaker, an ultra-comfy merino underwear bottom built for everyday wear. Made from Icebreaker's lightweight 150 g corespun merino blend, it combines merino's natural softness and temperature regulation with added durability from a fine nylon core and a hint of stretch. The hipkini cut offers flattering coverage that sits smoothly under everything from leggings to jeans.

Key Features:

• Merino corespun jersey that's soft, breathable, and durable enough for daily use.
• Hipkini silhouette with low-profile elastic at the waist for a secure yet gentle fit.
• Lightweight 150 g fabric ideal as a year-round base layer.
• Flat seams to help reduce rubbing on active days.

Why It's Good:

• Merino wool is naturally odor-resistant and thermoregulating, meaning fewer washes and more wears between laundry days.
• Icebreaker focuses on merino from responsible sources, offering a natural alternative to fully synthetic underwear.
• A comfortable, go-to cut you'll wear on repeat supports a more streamlined, less wasteful wardrobe.

Fit & Care: Slim, stretchy fit that runs true to size; if you prefer a looser feel, consider sizing up. Machine wash warm or cold on gentle, avoid fabric softeners, and line dry when possible to preserve fibers and elastic.

Style Notes: Pair your Icebreaker Merino 150 Siren Hipkini with matching Siren bras or bra camis to create a breathable merino base layer for travel, work, or weekends.
