• Offset & Forward Stitching: Built with flatlock seams, shifted forward and away from the top of the shoulder to reduce friction when carrying running vests or hiking daypacks.

• Side Ventilation Splits: Tailored with functional splits at the bottom hem to augment natural airflow and allow extra mobility around the hips.

Care Instructions

• Washing: Machine wash cold (30°C) on a delicate or gentle cycle. Wash inside out with similar colors.

• Detergent: Use standard mild liquid soap. Do not use fabric softeners or bleach, as these alter the natural performance of the wool structure.

• Drying: Do not tumble dry. Flat dry in the shade to maintain the shape of the technical tailoring.

• No Ironing: Refrain from using hot irons or dry cleaning to protect the delicate, natural fibers.

Professional Tips from X-Boundaries

1. The High-Output Favorite: If typical 200g base layers leave you feeling overly sweaty during local trail running or speed hiking, this 150g weight is exactly what you need. It vents moisture instantly while protecting your skin from the elements.

2. Odour-Defying Tech: Like all Icebreaker products, the pure wool fibers naturally suppress the buildup of stink-causing bacteria. You can wear this top on multi-day running excursions or cross-border travel without a single worry about sweat odors.

3. Flattering Dynamic Fit: The combination of Dolman back stitching and forward side panels creates a structured, low-bulk look that clings comfortingly to the body without feeling tight or constrictive.

4. Tropical Defense: Don't hesitate to wear this in humid environments. The extreme breathability of ultrafine merino helps lift moisture vapor off the skin before it turns into liquid sweat, acting like a natural air conditioner.
