What to Compare Before Buying

  • Size: The inseam is stated for YMD, so compare the chosen size carefully against the wearer’s leg length.
  • Fit: These leggings are streamlined rather than loose. Check whether a close base layer fit is what you want.
  • Fabric feel: The inside is brushed and the outside is smooth. Compare that feel with what the wearer prefers under sportswear or clothing.
  • Layering use: They are described as thermal underwear and a base layer, so compare whether you need a lower-layer garment rather than outerwear.

Before You Decide

Confirm the selected youth size, especially the inseam, before choosing an offer. Also check that you want a streamlined base layer rather than a looser trouser style, and review the fabric blend if the feel of the garment matters for your use.
