GYMPHLEX / Boa Hood Jacket
GYMPHLEX
Founded in 1936 in Leicester, England, Gymphlex began as a manufacturer of training shorts for the British military. By the mid-1900s, the brand expanded into school gym uniforms, becoming widely recognized across the UK. Its products have been worn by the British national rugby team, the polo club once associated with Prince Charles, and prestigious prep schools such as ETON and HARROW—making it one of the most familiar athletic brands in Britain. 
Lightweight warmth with the brand’s original boa fleece
The material is Gymphlex’s original lightweight boa: 75% polyester and 25% acrylic. The lofty structure traps air for warmth while maintaining a surprisingly light feel. 
The lining uses sweatshirt fabric and brushed material for a soft, comfortable touch. Excellent breathability prevents overheating—one of the key reasons this jacket is beloved as an everyday outer layer. 
Signature details: round buttons, piping, and more
The first thing that catches your eye on a Gymphlex boa jacket is the round leather-covered button. Made from genuine cow leather, it develops character the more it’s worn—a refined detail for grown-up style.
The chest is adorned with the brand’s iconic griffin embroidery. 
Precise piping and careful construction make this a simple yet enduring piece designed for long-term wear. 
A balanced length that pairs well with wide-leg pants
The short length falls lightly over the hips for a clean, balanced look. With relaxed room around the shoulders, it feels comfortable even when worn true to size.
Pair it with wide-leg trousers or other voluminous bottoms for an effortless winter casual style. If you prefer a looser fit, sizing up is also recommended.
