Broadstone Long Sleeve Base Layer | Seamus Green

BROADSTONE BASE — Seamus Green

A timeless essential, designed for riders who value comfort and class.

The Broadstone Base is your go-to everyday technical layer, created with the same beautifully balanced fit as our much-loved Belle Base. It’s not second-skin like the Tyneham or Lulworth — instead, it offers a flattering, easy silhouette that moves with you while maintaining structure and confidence.

Soft, breathable and designed for performance, Broadstone delivers comfort without compromise. Subtle side slits enhance movement and shape, while the premium YKK zip adds durability and a polished finish. True to MAYSTON’s comfort-first approach, there are no internal labels — nothing to rub, irritate or distract you.

Finished in our signature Seamus Green and detailed with sleek MAYSTON embroidery around the collar and black MAYSTON silicone branding on the sleeve, it’s a piece that transitions effortlessly from yard mornings to everyday wear.
