The Icebreaker Women's Siren Hipkini pairs the natural performance of Merino wool with a flattering hipkini cut. Soft, breathable, and naturally odour-resistant — ideal for all-day wear from gym to street.

 

Technical Specs

  • Material Composition: 83% Merino Wool, 12% Nylon, 5% LYCRA® (Corespun fabric blend)

  • Fabric Weight: 150 Ultralight

  • Style / Cut: Hipkini / Classic hipster bikini brief coverage

  • Design Pattern: "Good Luck" graphics (clovers, horseshoes, and hearts on a heather grey base)

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.

Customer video review of Montbell Lightweight Duffle Bag 60L

60L duffel bag is ideal for porters and horse back. Very lightweight, fold down to small pack, strong zippers and materials. Seen it in action and decided to get one myself.

Bought this strap to attach to my Montbell hat, the strap is of high quality and the adjustment of the buckle is smooth and easy.

Montbell Hat Strap Unisex

Customer service was excellent. SingPost messed up delivery; sent me failed delivery due to incorrect address. Client service team followed up promptly to make sure I received parcel the following day. Size was incorrect and the team facilitated my 1-1 exchange without fuss. Overall very positive experience from the store

Montbell Unisex Award Jacket 50th - EXCELOFT® Water-Repellent

This is to replace what I’d lost on a recent trip. The goretex works very well, shielded me from sudden downpour. The cap is also very fitted for me, not all caps can do. Though the price here in SG is $20 more than what I got from Japan but it’s worth the buy!
