Custom Boys' Underwear in Interlock Knit with Heat Transfer Printing

Custom Boys' Underwear — Interlock Knit with Heat Transfer Printing

We build boys' underwear programmes from a tech pack or a physical reference sample. This Interlock Knit version is developed for brands that need a repeatable specification: the same cloth, the same hand feel and the same fit on every reorder. Fabric, trims, heat transfer printing and packaging are all specifiable, so the garment stays consistent across seasons and across production runs.

Most buyers come to us after one of these problems: minimum order quantities far above what a growing brand can absorb, or packaging that arrives crushed and unsellable. Our response is to fix the specification first — fabric weight, shrinkage allowance, stitch density and tolerance — before a single bulk metre is cut.

Quality control

Every bulk order is checked against the approved sample for shade, hand feel, measurements and workmanship. We record shrinkage, colour fastness and seam strength on the first bulk lot and hold the data as the reference for reorders, so boys' underwear batches stay comparable over time. Inspection photos and the measurement report are sent before the balance payment is due.

FAQ

What is the minimum order quantity?

Standard programmes start at 300 pieces per style and colour. We can split sizes across a size set, and for first orders we often accept a mixed-colour run to help you test the market.

How long does sampling take?

A first prototype is typically ready in 12 working days after the tech pack is confirmed, including fabric sourcing if the base cloth is not in our stock library. Revisions add about 3 days each.

What file formats do you need for artwork?

Vector files (AI, EPS, PDF) give the best print and embroidery results. For raster artwork please supply at least 300 dpi at the final print size. We digitise embroidery files in-house and return a sew-out photo for approval.

Can you match a specific colour?

Yes. Send us a Pantone TCX reference or a physical swatch. We return lab dips for approval and hold bulk shade within the agreed tolerance band before cutting.
