Polyester

What polyester is, and why it is the technical choice

When the job is a garment that has to do something - keep out the weather, move with the body, hold up in the field - that garment is usually polyester. It is the engineered fabric of company merch: stronger than cotton relative to its weight, quick to dry, and it keeps its shape. We carry it most visibly in our recycled softshell jackets, where a polyester face with a water-repellent coating is what keeps your team dry.

Polyester is the opposite of cotton in a specific sense: cotton is the comfortable default, polyester is the performance option. It holds its structure in difficult conditions where a cotton garment would soak through, and it stays fast-drying in ways cotton cannot. That is why it is the choice for outdoor work, field teams, trade-show crews and anyone who actually wears their merch to do a job.

How polyester prints

Polyester has one famous quirk, and it is good to know it before you order: white does not print in sublimation. Sublimation - the full-color, edge-to-edge decorative method that polyester is known for - works by dyeing the fibres themselves, so the printed colour becomes part of the fabric. But the process can only add colour to a light ground. A white or light garment takes a crisp full-colour result; a black garment cannot carry it, because the white simply has nothing to dye onto. This is not a quality failure, it is how the technique works - so when colour matters, start from a white or light polyester garment.

That same dye-into-fibre nature is why sublimation results feel soft and permanent on polyester: the print does not sit on top as a layer, it becomes the fabric. It is the technique we reach for on performance garments where a stiff printed panel would be wrong.

Look for the full detail on the [[edge-to-edge-sublimation|edge-to-edge sublimation]] page. And one logistics note: sublimation as a technique (and embroidery on poly garments) is not covered by our 48-hour fast track. On the technical fabric, the finish is not worth rushing - we quote the normal production window and deliver it well.

How to care for polyester

Polyester is easy to maintain, and its strongest selling point reappears here: it dries fast and holds its shape with minimal effort. Wash it cool or warm following the label, and do not use a hot iron - polyester is a synthetic fibre and heat is its weak point. No bleach. A gentle, cool cycle and it is ready again quickly. The water-repellent finish on a softshell is what gives it its weather resistance, so keep the garment clean and follow the care label to let that finish last.

When to choose polyester

Choose polyester when the garment has a job to do. It is the right call for:

• Outerwear and weather-resistant gear - softshell jackets that keep rain and wind off
• Sportswear and performance wear, where a cotton garment would hold sweat and slow you down
• Vest projects where quick-dry and shape-holding matter across a season

The point at which polyester drops out is the opposite of cotton: it is not the most breathable or the most comfortable-to-touch fabric for everyday desk wear. For a daily tee or polo that sees most of its life indoors, [[cotton|cotton]] or [[organic-cotton|organic cotton]] is usually the better call. Polyester is not "better" than cotton - it is better for something: weather, performance, shape-holding. Let the job decide.

How SoMerch fits

We carry recycled polyester in our performance range - our softshell jackets are made with recycled polyester and come through an OEKO-TEX-certified fabric. When you are deciding between fabrics, we are straightforward about the trade-off: cotton for comfort and print ease across the everyday range, polyester where the garment has to perform in the field. We match the material to the work, not the other way around. Start with [[merch-field-guide|the rest of the field guide]] when you want the full picture, and see [[cotton|cotton]] for the everyday side of the choice.

The short version

Polyester is the technical fabric of company merch - the choice when a garment has to resist the weather, hold its shape and dry fast. Its headline rule is a white-garment one in sublimation printing: white does not print, so we print full colour on light polyester and design accordingly. Care it cool and it lasts. Choose polyester for performance, cotton for everyday comfort, and let the job decide.
