Helly Hansen Sizing Guide UK: How to Find Your Perfect Fit and What’s Worth Buying

Helly Hansen is best known for its performance outerwear, ski gear, and sailing apparel—but figuring out your correct size can be surprisingly tricky. From thermal base layers to insulated jackets, Helly Hansen sizes can vary wildly across products, collections, and regions.

That’s why Tellar.co.uk exists: to give you instant, accurate size recommendations based on your actual measurements—free of charge.

Is Helly Hansen True to Size?

Helly Hansen garments are engineered for performance—but that can mean fit is tailored for movement rather than streetwear sizing. Here's what to know:

Men’s Sizing Overview

Shell jackets and waterproofs run true to size with layering room
Base layers run slim—they’re designed for next-to-skin wear
Insulated ski jackets may feel bulky if you size up too far
Trousers and bibs often run long in the leg

Women’s Sizing Overview

Down jackets and fleeces often run small, especially at the bust
Salopettes and snow trousers can be snug at the hips
Base layers and leggings run slim—size up for comfort

Most size confusion happens because Helly Hansen products are built for activity-specific movement, not everyday fashion.

For the most accurate fit, we recommend using Tellar.co.uk to match your body measurements to Helly Hansen’s technical sizing.

How to Measure Yourself for Helly Hansen

The 3 essential measurements you need for outerwear:

Chest/Bust (fullest point)
Waist (natural waist, not low-rise)
Hips (widest part of your seat)

These are the measurements Tellar.co.uk uses to match you to your best-fitting Helly Hansen size, based on how the brand cuts its jackets, layers, and trousers.

Why Helly Hansen Sizes Vary

Helly Hansen uses different sizing standards depending on:

Region: EU vs UK vs US versions can differ
Product Type: Base layers, shells, and puffers all have different intended fits
Use Case: Ski jackets vs sailing gear vs hiking layers
Gender: Women’s sizing runs closer to EU models, often tighter at the bust and hips

Tellar takes all these factors into account to adjust sizing logic by garment type and measurement priority.

What’s Worth Buying from Helly Hansen?

If you’re building a winter or adventure-ready wardrobe, here’s what’s worth the investment:

🧥 Shell & Ski Jackets (e.g. Alpha, Odin, Crew)

Waterproof, breathable, and surprisingly durable. Use Tellar to match layering sizes underneath.

🧤 Base Layers (Lifa, Merino Blend)

Slim fit by design—ideal for skiing and mountaineering. Use your bust or chest measurement to avoid tightness.

🧢 Sailing Gear (Jackets, Trousers)

Precision-fit for movement; trousers often come up long. Tellar adjusts for inseam and waist differences.

🩳 Fleece & Mid Layers

Usually more generous—best bought true to size or sized down for slim layering.

Avoid the Most Common Helly Hansen Fit Mistakes

❌ Guessing your size from general EU/UK conversions

Tellar handles the conversions for you—automatically.

❌ Assuming ski jackets fit like streetwear

They don’t—especially if you don’t layer correctly underneath.

❌ Ignoring hips when buying salopettes

A snug hip fit can ruin mobility. Tellar prioritises your largest measurement for the most accurate match.
