Engel · Kids Merino Wool & Silk Base Layer Leggings
Extra-Fine Merino Wool & Silk Thermal Leggings for Kids
A featherweight 190 g/m² base layer in 70% organic merino wool and 30% mulberry silk — soft enough for sensitive skin, warm enough for ski days, and breathable enough to wear year-round. Made in Germany by Engel, IVN BEST and GOTS certified.
Engel — Germany’s heritage natural fiber maker since 1927
Engel has been knitting organic wool, silk, and cotton garments in Schorndorf, Germany, for nearly a century. They’re one of the most respected names in European natural fiber clothing, trusted by Waldorf families, midwives, and parents who want chemical-free clothing against their child’s skin.
Every Engel piece is GOTS and IVN BEST certified — the strictest organic textile standards in the world. The wool is kbT (kontrolliert biologische Tierhaltung), meaning it comes from certified organic farms with strict animal welfare requirements: no mulesing, no synthetic pesticides on pastures, and no harmful treatments on the fiber. Dyes are free from heavy metals and AZO compounds.
A true year-round base layer
These thermal leggings are the most versatile wool/silk piece in the Engel lineup. Wool naturally regulates body temperature — warming when it’s cold, releasing heat when it isn’t — which is why the same pair works for January skiing and September camping.
Worn against the skin under jeans, snow pants, or school uniforms. Adds warmth without bulk for skiing, sledding, hiking, or cold-classroom days.
Soft enough to wear on their own under a tunic or dress in transitional weather. Breathable enough that kids don’t overheat as the day warms up.
Many parents use these as wool sleep pants. The temperature-regulating wool/silk blend helps kids who run hot or kick off blankets stay comfortable all night.
For active kids skiing, hiking, or playing outdoors in cold weather: layer under fleece-lined pants or snow pants. For everyday winter wear: layer under jeans, leggings, or school pants. For sleep: wear on their own with a wool or cotton pajama top.
70% organic merino wool, 30% mulberry silk — 190 g/m² fine rib knit
Extra-fine merino at approximately 19.5 microns — the softness range used for next-to-skin baby and children’s clothing. Naturally temperature-regulating, breathable, odor-resistant, and moisture-wicking. Sourced from kbT-certified organic farms.
Real mulberry silk softens the hand of the fabric and adds a subtle sheen and stretch. Silk is the gentlest fiber for sensitive skin and makes this the ideal first wool layer for children who haven’t worn wool before.
A lightweight mid-weight fabric that provides real warmth without bulk. The fine rib pattern stretches with movement and lies flat under other clothing — no bunching or visible seams under jeans.
Knit, sewn, and finished in Germany. GOTS and IVN BEST certified end-to-end — covering the wool farming, processing, dyeing, and final garment construction. No harmful chemicals, AZO dyes, or heavy metals.
Key features
Merino wool actively responds to body temperature — insulating in cold weather and releasing heat when active. Kids stay warm without overheating during play.
The 19.5-micron merino combined with 30% silk is genuinely soft — not the scratchy wool of decades past. Suitable for most children with eczema or sensory sensitivities.
Wool can absorb up to 30% of its weight in moisture before feeling damp. Sweat moves away from the skin, keeping kids dry under snow gear or during high-effort play.
Wool resists bacteria growth, so these leggings stay fresh through multiple wears. Air them out between uses — full washing is rarely needed weekly.
Two of the strictest organic textile certifications in the world. No pesticides on pastures, no harmful dyes, no chemical finishes — verified at every stage.
Engel construction is durable enough that these leggings often pass between siblings. With proper wool care, they hold shape and softness for years.
European sizing by height — 2 to 16 years
Engel uses standard European children’s sizing based on the child’s height in centimeters. Each size corresponds to an approximate age range. European sizing runs slightly slim — if your child is at the upper end of an age range or tall for their age, size up.
| EU Size | Approx. Age | Child Height |
|---|---|---|
| EU 92 | 2–2.5 years | Up to 92 cm / 36 in |
| EU 104 | 3–4 years | Up to 104 cm / 41 in |
| EU 116 | 5–6 years | Up to 116 cm / 46 in |
| EU 128 | 7–8 years | Up to 128 cm / 50 in |
| EU 140 | 9–10 years | Up to 140 cm / 55 in |
| EU 152 | 11–12 years | Up to 152 cm / 60 in |
| EU 164 | 13–14 years | Up to 164 cm / 65 in |
| EU 176 | 15–16 years | Up to 176 cm / 69 in |
Measure your child’s height and choose the size at or just above that measurement. Wool/silk has a small amount of natural stretch, but for older kids who are growing fast or for use as pajama bottoms (where you want a relaxed fit), sizing up gives you longer wear.
What you should know before ordering
Kids in cold-climate winters who need a real base layer. Children with eczema or sensitive skin (the silk content makes this the gentlest wool option Engel offers). Kids who run hot at night and kick off blankets — the wool/silk blend regulates body heat better than synthetic pajamas. Families building a chemical-free wardrobe.
Fine merino at 19.5 microns is genuinely soft — meaningfully different from coarse traditional wool. The 30% silk content adds another layer of softness. Most children, including many with sensory sensitivities, find these leggings comfortable. That said, a small percentage of people are still sensitive to any wool. If your child has reacted to wool before, this wool/silk blend is the gentlest place to start.
These are not throw-in-the-machine-with-everything leggings. Wool requires hand washing or a wool cycle in cold water, and they must be laid flat to dry. Hot water, agitation, or tumble drying will felt and shrink wool — that’s a real risk worth knowing. Once you have a wool wash routine, it takes minutes; until then, plan for that learning curve.
Engel pieces sit at a heritage European price point. The value comes from durability (commonly passed between siblings), certifications you can verify, and the genuine performance of the fiber. If you’re comparing to fast-fashion synthetic base layers, the price gap is real — but you’re buying a different category of garment.
How to wash wool/silk leggings without ruining them
Wool naturally resists odor and rarely needs frequent washing — airing between wears is often enough to keep these leggings fresh. When a full wash is needed, use cool water with a wool-specific detergent like Eucalan or Sonett wool wash (regular detergents contain enzymes that damage wool fibers). Hand wash, or use the wool/delicate cycle on your machine if it maintains consistent cold water temperature.
Press water out gently — never wring or twist. Lay flat on a clean towel, roll the towel to absorb extra moisture, then unroll and lay flat to air dry away from direct heat. With this routine, wool/silk leggings hold shape and softness for years and are commonly passed between siblings.
Hot water, agitation, and tumble drying cause wool to felt and shrink — permanently. If you accidentally machine wash on a regular cycle, the leggings may shrink one to two sizes. The wool care routine above takes about five minutes once it’s habit.
