Do these run true to size? How do I pick the right size?

Our sets are designed to fit snugly as a base layer. When in doubt, size up — it's the safest choice for a whole season of wear.

Is this fleece lined thermal set itchy?

No itchy. The set is made from a soft cotton & acrylic blend with a smooth fleece lining, and we pay extra attention to comfort details: no scratchy tags, soft seams, and a gentle waistband.

How warm is this set?

This is a heavyweight, fleece-lined underwear set — built for real winter. Buyers have used it in 0°F weather, blizzards, ski trips, sledding, and ice skating and reported their kids stayed warm and dry.

Will this shrink or pill in the wash?

Proper care makes a big difference. Buyers who washed ours in cold water and tumble dried low report it "never shrank" and held its softness all winter.
