North Sails is a brand with deep nautical roots—founded in 1957 by Lowell North, a champion sailor turned sailmaker. Today, it blends technical sailing apparel with eco-conscious lifestyle fashion. But whether you’re shopping for a windproof jacket or a casual polo, one question always comes up: Does North Sails run big or small?

🌊 Tellar.co.uk matches your body measurements to North Sails’ real sizing data (plus 1,500+ other brands). We send you a free measuring tape, offer instant size recommendations, and eliminate the need for guesswork. Always free. No catches.

In this post, we’ll explain how North Sails clothing fits, how it compares to UK sizing, what to expect from their outerwear, polo shirts, trousers and more—and how Tellar ensures the perfect fit every time.


North Sails: Performance Meets Lifestyle

North Sails started with high-performance marine gear but has evolved into a dual-purpose brand: part technical sailing equipment, part sustainable fashion label. Their range now includes:

  • Offshore and coastal sailing jackets

  • Quilted and down insulation

  • Polos and sweatshirts

  • Smart-casual chinos and shorts

  • Eco-focused basics made from recycled fabrics

However, because they serve two distinct audiences, sizing can vary based on whether you’re buying technical gear or lifestyle collections—which is exactly why Tellar.co.uk is so helpful.


So—Does North Sails Run Big or Small?

North Sails generally runs true to size, but with some variation:

  • Sailing jackets tend to run large for layering and freedom of movement

  • T-shirts, polos, sweatshirts tend to run true to size or slightly fitted

  • Chinos and trousers run true at the waist but slim through the leg

  • Puffer jackets and mid-layers fit true with a performance cut

Because most product listings don’t include full measurements, the smartest way to shop is using Tellar’s Store Size Lookup Tool, which takes your chest, waist, hip, and height—and maps them to North Sails’ actual garment specifications.

North Sails’ sizing varies depending on whether you’re buying from their performance line or lifestyle collection:

  • Technical gear is cut larger for movement and layering

  • Lifestyle apparel is slimmer and more tailored

  • Some items are unisex, which can mislead women on shoulder fit and length

  • Product pages often lack garment measurements—leaving you to guess
