Trespass Size Guide: How to Find Your Perfect Fit and What’s Worth Buying

Trespass is a go-to brand for functional outdoor gear—whether you're hiking in the Highlands, skiing in the Alps, or simply braving a British downpour. But like many outerwear brands, sizing at Trespass can feel inconsistent across product categories.

That’s where tellar.co.uk comes in. We match your measurements to over 1,500+ brands, including Trespass, in real-time. With our free sizing tool, you'll never second-guess your coat, fleece, or hiking trouser size again.

Why Trespass Sizing Varies (And Why It Matters)

You’d think outdoor brands would be consistent. But Trespass, like many others, manufactures a wide variety of garments—thermal base layers, padded jackets, walking boots, ski pants—all of which are cut differently depending on insulation, activity level, and fit.

Trespass coats and jackets often run large to accommodate layering.
Fleeces and midlayers tend to be more fitted, especially in women’s sizes.
Ski trousers can vary massively based on fabric stretch and intended mobility.

If you’re guessing based on your usual high-street size, you may end up with sleeves too long, trousers too tight, or a jacket that doesn’t zip comfortably.

That’s why Tellar.co.uk’s bespoke body-matching system is the easiest way to find your exact size in Trespass, without needing to return or re-order.

Popular Trespass Items Worth Buying

Not sure what to shop for? We’ve done the legwork. Here are the top-rated products that are worth investing in from Trespass.

1. Trespass DLX Performance Jackets

Built for the serious adventurer, the DLX range includes waterproof and windproof outerwear that punches above its price. These tend to run roomy, so make sure your Tellar profile is updated before buying.

2. Ski and Snow Trousers

Often worn over thermal leggings, sizing here can be tricky. Tellar.co.uk accounts for your hip-to-waist ratio, so you don’t get a saggy waist or tight thighs.

3. Trespass Base Layers

Ideal for layering, especially in colder months. These have a much slimmer fit and often come up small, so using your Tellar match ensures a comfortable close-to-skin feel without restriction.

4. Walking Boots and Footwear

While Tellar is expanding into footwear sizing (coming soon), we recommend trying boots in-store or going a half size up for thick socks. Look out for this in our upcoming Footwear Fit Guide.

Real-Time Size Matching: Better Than Generic Charts

Traditional size guides are vague and outdated. Tellar’s technology doesn’t just tell you "Medium" or "UK 12". It cross-references your exact body measurements with the sizing quirks of each Trespass product category.
