Pricing and Minimums for Custom Shorts Orders
Pricing for custom shorts at MontForge depends on shell fabric (polyester interlock is the entry tier, dri-FIT and rPET are mid-tier, modal and tri-blend are premium), decoration method (screen print is the lowest cost per piece, sublimation adds print setup, embroidery adds digitizing), construction complexity (standard short sleeve is the baseline, raglan and drop-armhole add setup), and order quantity. shorts typically run 15-20% cheaper than racerback tanks because of simpler armhole construction. MOQ starts from 100 pcs per color and style..

Customer Success Stories — From Startup Drop to International Retail
Scaling UKs Premier Street Activewear Label — Montirex
- 30 Pcs
Initial MOQ Order
- €130 Million
Annual Retail Scale
When the founders of the prominent UK brand Montirex first approached the MontForge Dongguan manufacturing center, they were ambitious young designers looking to introduce highly technical, stylish activewear to the European market, starting with limited micro-drops of 30 pieces.
Their biggest obstacle was finding a factory capable of delivering flawless technical fit draping on athletic t-shirts at a low starting volume. Traditional factories offered bulky, off-the-shelf patterns. MontForge stepped in, utilizing our deep digital pattern library to custom-engineer lightweight athletic fit blocks with specialized mock neck collar and color-locked sublimation panel designs.
By maintaining a fast sampling speed of 7-10 days, MontForge enabled Montirex to rapidly test, iterate, and launch products. Today, Montirex is sold across major European sports retail empires like JD Sports and Footasylum, standing as one of Europes fastest-growing activewear brands.
