Key Features

• Corespun Fabric: Premium merino fibers are wrapped around a nylon core to dramatically increase durability and tear resistance while keeping pure merino next to your skin.

• LYCRA® Elastane Stretch: Provides a flexible, form-fitting stretch that moves seamlessly with your body without sagging.

• Forward-Set Side Seams: Side seams are shifted slightly forward to reduce bulk and completely eliminate chafing or friction points under heavy pack hip belts.

• Natural Odor Management: Inherent antimicrobial properties naturally resist odor buildup, keeping you fresh all day.

Care Instructions

Protect the delicate, ultralight fibers of your technical underwear with these guidelines:

• Wash: Machine wash cold (30°C) on a gentle cycle. Wash with like colors.

• Detergent: Use a mild or wool-specific detergent. Never use fabric softeners or bleach, which degrade wool fibers and block moisture absorption.

• Drying: Do not tumble dry. Line dry immediately in the shade.

• Ironing / Dry Cleaning: Do not iron prints or waistbands. Do not dry clean.

X-Boundaries Professional Tips

• The Ultralight Backpacker's Secret: Thanks to merino's supreme odor resistance, you only need to pack two pairs of Siren Hipkinis for a week-long trekking trip. Wear one while the other is drying after a quick trail rinse.

• The Anti-Chafe Base: If you struggle with thigh or hip chafing under heavy exploration packs, the forward-set seams on the Siren Hipkini are a game changer. They align perfectly flat underneath technical hiking pants and harnesses.

• Prevent Friction Holes: Because 150g ultralight wool is fine, wash your technical underwear inside a small mesh lingerie bag. This prevents the delicate jersey fabric from catching on aggressive hardware like bra hooks, velcro, or denim zippers in the wash cycle.
