Our jackets and vests vary slightly from style to style just because of functionality. For the best possible fit, head over to our size charts and match yourself up. For a better idea, each individual item page has its own product specific size chart.

First Manufacturing was started in New York and still operates out of its home office in Oceanside, NY. We own our own Factory and Tannery located overseas that produces most of our jackets and vests including all of our customs.

If you’d like to carry First MFG Co. Products or any other brands that we produce, send us an email at

Yes. We have our fashion line called Whet Blu.

We also carry a brand called Atrox USA which houses Adventure, Sport, and Outdoors gear.

We manufacture vests, jackets, and other garments for many companies. If you are looking for garment manufacturing services contact us.

We do carry tall sizes in a select few of our jackets but we can custom order any jacket or vest in tall sizing using our Custom Program.   


We can customize almost every Jacket and Vest in our production line.

Customs take anywhere from 4-6 weeks to complete. Jackets may take a little longer. After they are inspected by our team in New York, they’re shipped straight to your door.

You can upload your image straight to our custom vest builder or email it to us at with your order number in the subject.

We cannot customize an already existing jacket. Our Customs are built from the ground up and personalized for each individual.

We do not sew on patches.

We have a full line of Exotic embossed leathers available on our Custom Builder and we’re adding more every month.

We do not currently offer this option due to the chance of error. The last thing we’d want to do is take your grandfathers old flannel and cut it to the wrong size by accident.

Each custom is handmade by our team at our factory. We receive over 300 custom orders per month and are growing by the day.
