Technical cargo
Bellows gussets, reinforced knees, bartacks, YKK zippers, snaps, nylon webbing, and relaxed or articulated legs support utility.
Pattern-led woven bottoms
Custom Trouser Manufacturing
Fenalt manufactures technically demanding trousers with precise grading, heavy-duty seam machines, stable fabrics, and managed quality control.
From cargo and tailored chinos to oversized streetwear, we manage fabric and lab dips, pattern engineering, sampling, production, inspection, and DAP or FOB dispatch.
Direct answer
A managed trouser production lifecycle
Fenalt manages pattern and fabric procurement, including combed compact ring-spun cotton and technical synthetics, then coordinates a physical sample in 10–15 days and bulk production in 15–20 days after PP sign-off.
Each program receives on-site quality control, technical POM review, fabric and trim checks, and final ANSI/ASQ Z1.4 Level II inspection with an AQL 2.5 threshold before DAP courier or FOB export.
Silhouette engineering
Cargo, tailored, and oversized blocks
02
Tailored chinos and slacks
Italian slant pockets, jetted backs, curtain waistbands, slim, tapered, or straight blocks, and compacting or stenter control create a clean profile.
03
Streetwear oversized
Dropped crotch, wide openings, elastic or drawstring waists, high-GSM twill or heavy French Terry hybrids, screen print, 3D embroidery, and silicone treatments support the look.

Material selection
Fabric weight changes the trouser behavior
| Fabric | Composition | Weight | Best suited for |
|---|---|---|---|
| Cotton twill | 100% combed cotton | 240–320 GSM | Classic chinos and uniforms |

| Nylon Taslan | Polyamide | 120–180 GSM | Techwear and track trousers |
Technical construction
Build the load points into the pattern
Trousers need controlled seam, pocket, waistband, and hardware engineering to preserve fit and function.
Seams
Inseams and outseams use five-thread safety stitch or double-needle flat-felled construction.
Stitch density
10–12 SPI balances strength and puckering control in woven trousers.
Stress points
Bartacks reinforce pocket corners, belt loops, fly ends, and other load points.
BOM and hardware
Pocketing is typically 130–150 GSM cotton or poly; waistband fusing and YKK brass or nylon-coil zippers are specified by use.
Typical BOM and finish
Pocketing is typically 130–150 GSM cotton or poly. Waistbands use specified fusing. Fly hardware can be YKK #5 heavy denim or twill brass or nylon coil. Custom Cordura, GRS recycled nylon, and OEKO-TEX requirements are scoped to the approved product specification.

Questions and answers
Custom trouser manufacturing FAQs
What is the minimum order quantity?
Fenalt's standard MOQ is 50 pieces per style.
Can you work from DXF, RUL, or a tech pack?
Yes. Fenalt accepts DXF or RUL patterns and tech packs, then applies standard grading and POM review.
Can you source technical or certified fabrics?
Yes. Cordura, GRS recycled nylon, OEKO-TEX, and other requested constructions can be scoped to the product specification.
What are the standard tolerances?
Major POMs are generally ±0.5 inch and minor POMs ±0.25 inch, subject to the approved measurement chart.
Can we develop custom hardware?
Yes. Branded buttons, rivets, zipper pullers, and other hardware are available, though custom development can require higher minimums.
How do you manage shrinkage?
Fabrics receive three-cycle wash shrinkage testing before bulk cutting, and patterns are adjusted for the measured result.
What does DAP or FOB mean for delivery?
DAP delivers to the named place with local duties and taxes handled by the recipient. FOB Chattogram covers loading at the origin vessel point, with onward routing managed by the buyer's forwarder.
