Minku Apparel is a custom t-shirt manufacturer for Seattle brands, producing boxy heavyweight tees from 50 pieces per design with full private-label finishing. We run 180 to 240 GSM combed cotton, decorate in-house with screen print, DTG, and embroidery, sample before bulk, and ship DDP to your Seattle door in roughly 5 to 8 days by air. For a label rooted in the Pacific Northwest’s layering-first, heavyweight aesthetic, this is the factory that builds the base of your rotation.
This page covers how we make tees for the Seattle market: the cotton weights and cuts suited to a rainy, layering climate, in-house decoration and private labelling, MOQ and pricing in dollars, sampling, and DDP shipping with US duty already handled.
Why the heavyweight tee fits Seattle right now
Seattle’s aesthetic was forged in grunge, and its DNA is still layered, muted, and heavyweight – flannel over a tee, hoodie over a tee, rain jacket over all of it. In a city where it rains much of the year and the tee is almost always a base layer, the shirt has to carry weight and structure so it reads as intentional under an open layer, not as an afterthought. The Pacific Northwest’s understated, function-first taste rewards a substantial combed-cotton tee with a clean drop and honest construction over anything flashy. That is exactly the piece a Seattle label needs at the core of its lineup.
Cotton weight, fit, and cut for the Pacific Northwest
Weight matters even more when the tee lives under a layer. We run combed cotton from a 180 GSM mid-weight to a dense 240 GSM heavyweight, in a boxy structured drop, a fitted classic, an oversized block, or a cropped cut. Ring-spun and combed yarns give a smooth print surface and a soft hand, with side seams, double-needle stitching, and a ribbed set-in collar that holds shape under repeated layering. For Seattle, a 240 GSM heavyweight combed cotton is the signature weight – dense, structured, and built to anchor a layered fit through a wet, cool year. Every measurement is logged so reorders match.
Decoration and private label for Seattle brands
We run every decoration method in-house. Screen print gives bold, opaque graphics with plastisol or soft water-based inks, DTG handles photographic and multi-colour art with no minimum penalty, and puff or flat embroidery adds a premium chest or sleeve mark. Garment dye, acid wash, and tie-dye deliver the washed, muted, worn-in finishes that suit Seattle’s grunge-descended palette. Every tee carries your woven inside label, neck tape, and hem tag, so it reads as your brand from the fabric out. Owning the blank – your weight, your drop, your inside branding – is what makes a Seattle label a product rather than a printed blank.
MOQ and pricing in dollars
Minimum is 50 pieces per tee design, so a Seattle founder can test a graphic or a heavyweight blank before scaling. Pricing is quoted in dollars and tracks cotton weight, fit, and decoration, dropping as you move into reorders. Because a heavier tee uses more cotton, weight is a real cost driver – we keep that transparent so you can choose the right GSM for your price point.

Sampling before bulk
We sample before every bulk run. Once specs are locked we produce a pre-production tee so you can feel the cotton weight, check the drop and collar, and confirm the print registration before the run. Send artwork, a reference tee to match, or a full tech pack – we help build one if you do not have it. Every spec is recorded, so the sample you approve is the tee you receive, and reorders match it.
DDP shipping and duty to Seattle
Tees are light per unit, so air freight is efficient and we ship Delivered Duty Paid. DDP means US import duty and customs handling are already in your landed price – no broker bill after delivery. Air freight lands your order at a Seattle address in about 5 to 8 days once QC clears. Cotton knit tops carry their own US HTS duty rate, and under DDP we build that into your quote up front. Because tees pack flat and light, replenishing your heavyweight core between drops is fast and predictable.
