SmartKnitKIDS Seamless Undies for Boys are soft, stretchy boxer briefs designed for children who find standard underwear uncomfortable, irritating or distracting.

Made completely without seams, these boxer briefs help remove the lumps, bumps and stitching that can cause discomfort throughout the day. They are ideal for children who are sensitive to seams, labels, waistbands or tight leg openings.

The soft, form-fitting fabric gently hugs the body without feeling restrictive. The waistband and leg openings are non-binding, with no elastic to dig in or create pressure marks.

SmartKnitKIDS Seamless Undies are made from a blend of Coolmax and Lycra. Coolmax helps wick moisture away from the skin and supports temperature regulation through the structure of the yarn, rather than through added chemicals.

Helpful Sizing Notes

These undies are knitted in one piece, so they may feel slightly thicker than standard underwear when first removed from the packet. They are designed to stretch and shape to the body once worn.

The fit is similar to “magic gloves” – they may look small or a little different at first, but they are made to stretch comfortably to the body’s contours without putting too much pressure around the edges.

If your child is between sizes or on the cusp of a size, we recommend sizing down. These undies are extremely stretchy and can often be worn beyond the suggested age guidance.

What can it be used for?

  • Everyday underwear for school, home and outings
  • Helping reduce irritation from seams and elastic
  • Supporting children who are easily distracted or distressed by uncomfortable clothing
  • Wearing under school uniform, casual clothing or sportswear
  • Providing a soft underwear option for children with sensitive skin

Care & Use

Follow the care instructions on the garment packaging. For best results, choose the correct size and allow the fabric to stretch naturally to the body when worn.

  • Children who dislike seams in their underwear
  • Children who find standard waistbands or leg openings uncomfortable
  • Children who are sensitive to labels, stitching, elastic or bulky fabric
  • Children who need soft, comfortable underwear for everyday wear
  • Children who struggle with getting dressed due to discomfort from clothing
  • Children who prefer underwear that feels smooth and consistent against the skin
