Kids' Classic Thermal Merino Base Layer Crew

Our Kids' Classic Thermal Merino Base Layer Crew is made of 100% responsibly sourced Merino wool to help your little ones stay comfortable on snow days and activities in the mountains. With a flatlock seam construction designed to help prevent chafing, a crew neck built with set-in long sleeves, and all of the benefits of Merino, this kids' base layer will help them enjoy winter more.

Midweight 250g/m² For Real Cold
Same proven 250g/m² ZQ-certified Merino as the adult Classic Thermal crew — heavy enough for sled days and ski lessons, breathable enough that your kid doesn't overheat on the lift ride up.
100% Merino Wool Fabric
Single-jersey knit of 100% Merino wool delivers moisture management, body-temperature regulation, and natural odor resistance. Interlock construction keeps the next-to-skin layer soft against young skin during long schoolyard days.
Slim Fit, Kid-Sized Proportions
Engineered in child proportions — not a scaled-down adult — so the cut follows a kid's torso without excess fabric bunching under a snowsuit, jacket, or ski bib.
Set-In Crew Neck With Long Sleeves
Classic crew neckline sits cleanly under chin guards and balaclavas without bulk. Set-in long sleeves reach the wrist without riding up when arms go overhead on the monkey bars or while poling a ski.
Flatlock Seam Construction
Flatlock seams throughout sit flat against skin to minimize chafing under layers and packs. Built for active kids who won't sit still — the seams don't catch or scratch through a full day outside.
Multi-Day Odor Resistance
Merino's natural odor resistance means the base layer stays wearable through a long ski weekend or a week of winter recess without needing daily washing — a real win when you're packing for family travel.
Multi-Activity Versatility
Built for snow play, ski school, sledding, winter hikes, and the playground. The temperature-regulating properties of Merino keep kids comfortable from the chairlift to the snack break and back.

Washing
Machine wash warm on a gentle cycle with like colors. Use a mild detergent — avoid fabric softeners and bleach, which coat the Merino fibers and reduce moisture-wicking and odor-resistance performance. Wash with similar colors to prevent dye transfer on bright kid colorways.
Drying
Tumble dry low. High heat can shrink Merino wool fibers and damage the interlock knit over time. For longest life, lay flat to dry when possible — air-dried Merino retains its shape and loft through more wear cycles, important for hand-me-down between siblings.
Ironing & Decoration
Cool iron as needed. Do not iron decoration. Printed graphics, heat-transfer logos, and color-block panels can scorch or peel under direct high heat — use a press cloth if ironing is necessary.
Dry Cleaning
Do not dry clean. The harsh solvents used in commercial dry cleaning strip the natural lanolin from Merino wool, leaving fibers brittle and reducing the temperature-regulating properties that make the fabric perform.
Storage
Store folded in a dry, breathable space between seasons. Merino's natural odor resistance means you can wear it multiple times between washes — a key performance feature that makes it ideal for multi-day family trips and winter weekends away.

Merino Layer System — SW0SN110

Built For

Sled Days & Snow Play
15° – 35°F
The hill, the backyard snow fort, the school recess snowday. Midweight 250 holds warmth through hours of wet-snow play without the clammy chill a synthetic develops.
Ski School & Lesson Days
Below 30°F
Layer under a ski jacket and bib for first-chair through last-call lessons. Regulates output from the magic carpet to the chairlift queue without overheating.
Winter Hike & Snowshoe
20° – 40°F
Family winter hikes, scout snowshoe outings, cabin approaches. Slim fit tucks cleanly under a kids' puffy and breathes when the trail climbs.
Multi-Day Family Travel
10° – 45°F
Pack light for ski weekends and holiday trips. Merino's odor resistance lets one base layer cover multiple days of wear between washes — fewer items in the suitcase.
Build The Kids' System

Pair It With The Kids' Bottom

Match the Kids' Classic Thermal Merino Base Layer Bottom so your kid's upper and lower layers regulate as one system — same 250g/m² midweight, same 100% Merino, same kid-proportioned slim fit.

  • Same 250g/m² midweight matched warmth top to bottom
  • 100% Merino wool identical fabric feel
  • Slim kid-proportioned fit won't bunch under bibs
  • Hand-me-down ready holds shape season to season
Top It Off

Layer With The Kids' Outerwear

For real snow days, layer a kids' insulated jacket or ski jacket over the crew. Merino manages moisture from the inside while the outerwear blocks wind and precip from the outside.

  • Insulated ski jacket full-day snow protection
  • Kids' puffy midlayer extra warmth on bitter days
  • Snow bib or pants complete the lower system
  • Kids' Merino beanie head coverage under helmet

Prepared with intention.

Every product is carefully inspected and handled by our team before it ships. From fit and function to final details, we make sure each piece is ready for the outdoors ahead—so you can focus on the experience, not the gear.
