Equip your kids for cold-weather adventures with the ultimate thermal top. The Icebreaker Kids’ 260 Tech Long Sleeve Half Zip is a premium heavyweight base layer crafted entirely from 100% pure Merino wool. Designed to keep little ones warm and comfortable during winter vacations, ski trips, or frosty mountain hikes, this top delivers incredible insulation without any of the bulky weight or "scratchy" discomfort of traditional wool. The addition of a sleek half-zip neck offers quick, on-the-go ventilation for active kids who never seem to stop moving.

Key Technical Features

• 100% Pure Merino Wool (260 g/m² Heavyweight): Icebreaker's signature high-density weave designed to seal in core body heat while allowing moisture vapor to escape efficiently.

• Ventilating Half-Zip Neck: Features a high collar for maximum neck warmth that quickly unzips to dump excess heat when kids transition indoors or pick up the pace on the trail.

• Zip Neck Collar with Zipper Chin Guard: Equipped with a protective fabric garage at the top of the zipper to prevent the metal slider from pinching or rubbing against tender skin.

• Off-set Shoulder Seams: The seams are strategically shifted away from the tops of the shoulders to eliminate friction and pressure points when carrying a school pack or hiking daypack.

• Flatlock Construction: Flat-stitched seams eliminate interior ridges, guaranteeing an irritation-free, zero-chafing fit under heavier mid-layers or outer jackets.

Care Instructions

• Washing: Machine wash cold or warm inside-out on a gentle cycle with similar colors.

• Detergent: Use a mild liquid detergent. Do not use fabric softeners or bleach; these chemicals coat the natural wool fibers, destroying their inherent moisture-wicking and insulation capabilities.

• Drying: Line dry in the shade. Never tumble dry, as high heat will cause pure Merino wool fibers to shrink dramatically.

• Storage: Make sure the top is 100% dry before storing it flat. Keep it in a sealed cedar chest or moth-protected drawer to preserve the premium natural fibers.

Professional Tips from X-Boundaries

1. The Perfect Alpine Match: Pair this top directly with the Icebreaker Kids' 260 Tech Leggings to create a complete, high-performance thermal uniform. It is the gold-standard base layer configuration for sub-zero ski holiday environments.

2. No More "Lodge Meltdowns": Kids frequently overheat when stepping inside a heated ski lodge or restaurant after playing in the snow. The half-zip design lets parents unzip the collar instantly, allowing cool air to circulate so the child stays comfortable without needing a full outfit change.

3. Pack Less, Explore More: Because premium Merino wool is naturally antimicrobial, it prevents the buildup of odor-causing bacteria. Your child can wear this top for several days of active outdoor play before it needs a wash, saving massive amounts of precious suitcase space.

4. Excellent Drop-Tail Coverage: The cut features a slightly elongated hem to keep the lower back fully protected and covered, ensuring the top stays securely tucked into their pants even when they bend over to pack snowballs.
