LikeUU Children’s Merino Wool Thermal Underwear Set – Ultra-Warm Fleece Lined Base Layer

Keep your child cozy and dry throughout the coldest months with the LikeUU Thermal Underwear Set. Designed with a sophisticated triple-layer fabric system and premium Merino wool, this set offers superior heat retention without the bulky feel of traditional winter wear. Whether it’s for a special New Year celebration or daily winter play, this award-winning design ensures your child stays comfortable, breathable, and warm in temperatures ranging from 0°C to 20°C.

Key Benefits

Triple-Layer Thermal Protection:** Features a specialized three-tier structure: an outer wool layer to lock in heat, a middle layer for moisture evaporation, and a skin-friendly inner layer that wicks away sweat in just 3.5 seconds.

Non-Itch Merino Wool Technology:** Utilizing 17.5μm ultra-fine Merino wool and a 2024 French Design Award-winning spinning process, the wool fibers are encased to prevent skin irritation, making it soft and smooth even for sensitive skin.

Advanced Moisture Management:** The "one-way moisture conduction" fabric ensures that sweat is moved away from the body quickly and does not seep back, preventing the "damp chill" that often occurs after physical activity.

Enhanced Durability & Anti-Pilling:** Engineered with "Puff Fleece" technology, this fabric is tested to withstand up to 7,000 friction cycles—significantly outperforming standard thermal materials—to ensure it looks new even after heavy use.

Lightweight Warmth:** Despite its lightweight feel, the innovative construction provides double the warmth of standard layers, making it the perfect low-profile base layer for school uniforms or festive outfits.

Key Specs

Material:** 17.5μm Non-itchy Merino Wool blend with specialized "Puff Fleece" lining.

Fabric Technology:** One-way moisture conduction and rapid 3.5-second sweat absorption.

Design Recognition:** Winner of the 2024 French Design Award.

Performance Rating:** Tested for 7,000 friction cycles for superior anti-pilling.

Occasion:** Optimized for winter daily wear and "Year of Birth" (Ben Ming Nian) celebrations.

How to Use

Wear as a primary base layer directly against the skin to maximize the moisture-wicking and thermal properties.

The high-stretch fabric is designed for active movement, making it suitable for outdoor sports, school, or sleepwear.

Pair with a mid-layer and outer shell for extreme cold, or wear alone as loungewear in indoor heated environments.

Care & Safety

Skin Sensitivity:** While the innovative spinning process minimizes irritation, individuals with extremely sensitive skin should monitor for comfort during the first wear.

Washing:** Turn the garment inside out before washing to protect the fleece texture. Use a gentle cycle with mild detergent.

Drying:** To maintain the "Puff Fleece" integrity and moisture-wicking capabilities, air drying is recommended. Avoid high-heat settings in the dryer.
