About Musto: Technical Clothing With a British Edge

Musto is the go-to brand for sailing professionals, country sports enthusiasts, and serious adventurers. Known for its high-performance waterproof jackets, fleece midlayers, sailing salopettes and technical baselayers, Musto has also expanded into more lifestyle-led collections in recent years.

As a result, sizing across collections can vary—from oversized waterproof shells to close-fitting thermals.

That’s why using a smart tool like Tellar.co.uk gives you the edge: it maps your body to Musto’s garment specs, taking layering and use case into account.

So—Does Musto Run Big or Small?

Generally, Musto outerwear runs large (to accommodate layering), while base layers and thermals run small or fitted.

Here’s the general trend:

Sailing jackets & waterproofs – run large
Mid-layers & fleeces – run true to size
Base layers & compression – run small
Polos & tees – true to size
Trousers & salopettes – slim at the waist, roomy through thigh

Why Musto’s Sizing Can Be Tricky

Musto designs clothing for performance, not fashion, meaning:

Many items are intentionally oversized
Some garments are unisex, which affects fit for women
Layering assumptions aren’t always explained in product pages
UK sizing is used, but body length and proportion matters

Rather than relying on generic advice, Tellar.co.uk analyses Musto’s actual fit data across categories—and gives you an instant size match for what you’re buying.
