Key Features

100% Non-Superwash Merino Wool: Pure 250gsm merino wool left in its natural, untreated state without chemical processing, ensuring the softest, most breathable fibers that maintain wool's natural self-cleaning and temperature-regulating properties.

Two-Piece Versatile Set: Includes long-sleeve top with extra-high adjustable waistband (folds down to hips or stays high to cover tummy) and matching pants with long fold-down cuffs and fold-over closures to cover little toes.

Natural Temperature Regulation: Merino wool's unique fiber structure insulates in cold weather while remaining breathable in warmth, maintaining optimal body temperature without overheating or chilling during sleep or active play.

Moisture-Wicking Comfort: The thermal base set traps body heat while allowing perspiration to escape, keeping children warm and dry during extended wear, outdoor adventures, or overnight sleep sessions.

GOTS Certified Pure & Natural: Every Baby in Merino item is GOTS (Global Organic Textile Standard) certified using 100% certified organic fabric and ecological materials that don't harm the earth with harsh chemicals or dyes.

Soft & Itch-Free Design: Incredibly soft merino fibers ensure irritation-free all-day comfort, making these base layers ideal for children with sensitive skin, allergies, or eczema who cannot tolerate scratchy fabrics.

Understanding Non-Superwash Merino Wool

What "Non-Superwash" Means: Unlike superwash wool that's been chemically treated for machine washing convenience, non-superwash merino wool remains in its natural, untreated state. This preserves wool's inherent properties including superior breathability, natural antibacterial qualities, and self-cleaning abilities.

Why Choose Non-Superwash: Natural, untreated wool maintains its scales and lanolin, providing better insulation, moisture management, and odor resistance. It requires less frequent washing and when cared for properly, lasts longer than chemically treated alternatives.

Care Considerations: Non-superwash wool requires gentle hand washing or wool cycle care rather than regular machine washing, but the trade-off is superior natural performance and no chemical treatment exposure for your child's skin.

Creative Layering & Family Solutions

Perfect Sleep Sack Companion: Designed to harmoniously blend with Baby in Merino's sleep sack collection, providing additional warmth for colder nights or seasonal temperature variations without bulk or overheating.

Year-Round Base Layer Versatility: Functions as cozy pajamas during mild weather, essential base layer for winter outdoor play, or comfortable loungewear for everyday home activities throughout all seasons.

Growing with Snug Design: Thermal base layers are designed to fit snugly (close to the body) for optimal temperature regulation and layering, though sizing up provides a looser fit if preferred for your child's comfort.

Allergy & Eczema Friendly: The soft, itch-free merino wool is the best natural choice for children who suffer from allergies or eczema, providing gentle comfort without the irritation caused by synthetic or conventional cotton fabrics.

Reduced Laundry Burden: Merino's natural antibacterial and odor-resistant properties mean significantly less frequent washing compared to cotton or synthetic base layers, saving time, water, and energy while preserving garment longevity.

Health & Safety Advantages

Chemical-Free Natural Fiber: Non-superwash processing eliminates exposure to harsh chemicals used in superwash treatments, ensuring only pure, natural merino wool touches your child's delicate skin throughout extended wear.

Naturally Antibacterial & Odor-Resistant: Merino wool's inherent properties resist bacteria growth and odor development, maintaining freshness between washes while supporting healthy skin contact during sleep and play.

Hypoallergenic Gentle Comfort: Natural merino wool is hypoallergenic and gentle on even the most sensitive skin, making it ideal for babies and children with skin sensitivities, allergies, or conditions like eczema.

Breathable Temperature Safety: Superior breathability prevents dangerous overheating during sleep while maintaining warmth, supporting safe sleep practices and comfortable rest throughout the night.

Care Instructions

Merino wool needs far less washing compared to cotton and synthetic fabrics. Often simply hanging your merino garments outside on the line for a few hours is enough to refresh and renew them, thanks to wool's superior breathability and natural antibacterial properties.

When washing is needed:

Use environmentally friendly detergent and wash preferably by hand in lukewarm water or use wool (gentle) cycle at maximum 90°F (30°C)

Never soak merino garments as this destroys wool fibers

Use only soft spin and do not tumble dry

Press moisture in a towel, reshape, and dry flat

Do not dry in direct sunlight or close to heating sources

For moth protection, store wool in sealed plastic bags when not in use

Treat with environmentally friendly wool conditioner to preserve softness and moisture absorption

Natural Pilling: Because this wool has not been treated with synthetic coatings, natural pilling may occur where friction causes short fibers to migrate to the surface—this is normal and doesn't affect performance.
