Boys Base Layers FAQ

What do boys wear under a snowsuit?

A close-fitting base layer goes under the snowsuit. Deux par Deux makes boys' base layers to wear as the first layer, adding warmth without limiting movement on the ski hill or at recess. Put it under boys snowsuits.

Is a two-piece set or a one-piece thermal suit better for boys?

The Deux par Deux two-piece set is thick brushed jersey with a half-zip top and an elastic-waist pant. The one-piece has long raglan sleeves and an asymmetrical zipper. Both are made to go under a snowsuit.

What sizes do boys' base layers come in?

The Deux par Deux two-piece set is listed in sizes 2 to 14. The one-piece thermal suits run from 6 months to size 14, and the merino wool set from 2/3 to 12/14. Use the brand's size chart, and check baby boys base layers for the smallest sizes.

What is the merino set made of?

The Deux par Deux merino set is a two-piece base layer in soft merino jersey, with a long raglan sleeve top with a round neckline and a pull-on pant with a stretch elastic waistband. Check the product page for full details before you buy.

How should a boy's base layer fit?

Snug but not tight works best, so he can bend and reach in a snowsuit. Size by his height and the Deux par Deux size chart rather than age alone. Finish the outfit with mittens and gloves.
