GYMPHLEX
GYMPHLEX began in 1936 in Leicester, England, producing athletic shorts for the British military. In the mid-1900s, the brand expanded into school gym uniforms, spreading throughout the UK. GYMPHLEX has become a beloved British brand, with its products adopted as uniforms for the England national rugby team, the polo club once associated with Prince Charles, and prestigious British preparatory schools such as ETON and HARROW.

Original “AIR LIGHT FLEECY” fabric
GYMPHLEX’s original fabric features a deeply brushed reverse side that creates a soft, full-bodied feel while keeping the fabric lightweight.
The polyester blend helps the garment retain its shape, while the cotton adds a soft, comfortable feel. With just the right amount of stretch and structure, it offers easy comfort with a refined look that goes beyond ordinary casualwear.

Signature embroidery and thoughtful functional details
The easy-to-style crew neck design makes it a versatile choice for everyday wear.
The left chest features a small and refined “Griffin embroidery,” adding a subtle accent to the simple design.

The swing sleeves under the arms are the key feature of this design. They allow for easy movement while creating a flattering, three-dimensional silhouette with an effortless look. The result is a modern shape that looks naturally polished with minimal effort.
The cuffs and hem feature ribbing that provides a comfortable fit while adding subtle definition to the design.
A structured silhouette for a refined look
The dimensional silhouette looks stylish even when worn on its own. The structured fabric creates just the right amount of volume, giving the sweatshirt a refined look without feeling overly casual.
Easy to pair with denim or slacks, it works equally well for casual and polished outfits. A versatile everyday piece that makes it easy to achieve a polished look.
