Better Sleep. Better Play. Naturally. Kids’ MerinoSilk crews & leggings - breathable, soft, and sustainable.
Why parents LOVE MerinoSilk
Feel better knowing your child is wrapped in nature’s best fibers.
Our MerinoSilk is naturally designed to support your child in every moment, from restful nights to adventurous mornings.
Not all fabrics are created equal.
For over 20 years we’ve helped families choose better clothes that care for children and the planet.
Not all fabrics measure up the same, so here’s how our MerinoSilk compares to the rest.
Softness & Comfort
Breathability & Temp Control
Moisture Management
Durability & Longevity
Skin Sensitivity
Flame Resistance
Sustainability
Odor Resistance
Care
70% MERINO / 30% SILK
Silky-smooth, gentle on sensitive skin
Regulates body temp (warm in cold, cool in heat)
Wicks + dries fast, stays warm even damp
Strong natural fibers, resists wear, made to hand down
Naturally hypoallergenic, smooth against skin
Naturally flame resistant. Chars, doesn’t melt; safer for kids
100% renewable, biodegradable, no microplastics
Natural antibacterial properties → stays fresh longer
Easy to wash, keeps shape, dries fast
COTTON
Soft at first, stiffens with washing
Breathable but holds moisture (feels cold when wet)
Absorbs moisture, slow to dry
Shrinks/fades with washing, weaker over time
Can irritate if chemically treated
Burns quickly unless chemically treated
Natural but water/chemical heavy in production
Retains odor unless washed often
Shrinks, wrinkles
POLYESTER / SYNTHETICS
Can feel plasticky, traps sweat
Poor. Traps heat, causes overheating
Repels water but holds odor
Very durable but loses shape, pills
Can cause rashes/itch, not ideal for eczema-prone skin
Melts and sticks to skin - dangerous
Fossil-fuel based, sheds microplastics
Holds odor strongly
Easy care but sheds plastics in wash
MERINO / NYLON
Softer than synthetics, but less breathable than pure merino & silk
Merino helps, but nylon reduces breathability
Wicks, but nylon adds odor retention
Durable, but nylon can weaken merino’s natural structure
Usually okay, but depends on chemical finishes
Flame resistant due to merino, but nylon can still melt
Half-natural, half-synthetic → microplastic shedding
Some odor resistance, but nylon reduces effect
Easy care but sheds microplastics

"Love Them. My kids love the Nui Merino Silk Crew and matching Leggings. They keep them warm on winter nights as pajamas, cozy during the day for clothes, and they can be worn many times before washing."
