Montane is a go-to brand for outdoor adventurers who need performance gear that works as hard as they do. From ultra-lightweight jackets to breathable base layers and expedition-ready trousers, Montane delivers technical clothing for serious pursuits.
But finding the right Montane size—especially online—can be tricky. Their gear is designed for movement and layering, which means the fit can vary by product type and intended use. That’s where Tellar.co.uk, the UK’s leading free sizing tool, steps in to help.
In this guide, we’ll break down how Montane sizing works, how to get your best fit across men’s and women’s categories, and what’s worth investing in from this technical British brand.
About Montane: Technical Performance from the UK
Founded in the 1990s in Northumberland, Montane has become a favourite among climbers, runners, hikers, and expedition teams for its high-spec fabrics and lightweight construction. Trusted by endurance athletes and mountain professionals, the brand combines minimalist design with maximum performance.
Their gear is built for:
-
Fastpacking, fell running & ultra-races
-
Winter mountaineering and trekking
-
Technical layering systems for varied weather
-
Everyday activewear for cold climates
If you’re shopping for Montane, you’re likely chasing performance—but don’t let sizing inconsistencies hold you back.
Does Montane Run Big or Small?
Montane clothing generally runs true to size, but fit depends on intended use. For instance:
-
Montane Alpine jackets have a more technical cut and are designed to layer over base and mid-layers. They may feel roomier in the chest and arms.
-
Running pieces (like the Featherlite or Minimus lines) have a slimmer, more athletic fit, which may require sizing up if you prefer a looser feel.
-
Women’s sizing is slightly narrow in the hip and bust, particularly in base layers and close-fit midlayers.

How to Measure Yourself for Montane Gear
Performance fit relies on precision sizing—and Montane’s garments are built with movement and layering in mind. That’s why we recommend measuring yourself properly:
✅ What You Need:
-
A soft measuring tape
-
A fitted base layer (for accuracy)
-
3 minutes
✅ Measure:
-
Chest – Fullest part, under the arms
-
Waist – Narrowest point above hips
-
Hips – Widest part of your seat
-
Inside Leg – From crotch to ankle
Then go to Tellar.co.uk and enter these into our sizing tool. If you don’t own a tape, you can request a free measuring tape from us.
