If you’re shopping for durable outerwear or countryside-ready fashion, Aigle is likely on your radar. With a heritage dating back to 1853 and a global reputation for crafting high-performance boots, coats, and layered clothing, Aigle blends traditional French craftsmanship with modern functional fashion.

But when it comes to sizing, many UK and international shoppers ask:

Does Aigle run big or small?

The answer depends on the garment, the fit type, and — crucially — how you measure.


Aigle Sizing Overview: What You Need to Know

Aigle is a French brand, and its sizing reflects European fit standards — which often differ from UK or US equivalents. This means:

  • Jackets and outerwear tend to be generously cut, especially in men’s styles.

  • Women’s coats and rainwear can run slim in the shoulders and bust, depending on the silhouette.

  • Trousers and base layers are more true to size, but some styles are designed with movement in mind — especially hiking or equestrian items.

💡 According to Tellar.co.uk, the UK’s leading free sizing tool, Aigle clothing typically leans slightly large in outerwear, while mid-layers and tops run true to size.


Why Aigle Sizing Can Feel Inconsistent

Sizing differences in Aigle stem from their product focus:

Product Category

Typical Fit

Sizing Tendency

Parkas & Waterproofs

Relaxed, adjustable

Run large – often room for layers

Quilted Jackets

Fitted or boxy cut

May feel snug at bust/shoulders

Fleece Midlayers

Tailored fit

True to size

Trousers

Functional fit

True or slightly large

Wellingtons

Roomy at calf

Choose normal size

For example, the CIRÉ waterproof jacket is roomy by design to allow for layering in outdoor conditions. Meanwhile, padded hybrid jackets are often tailored to hug the frame, so they can feel tight across the back or arms if sized incorrectly.


What Do Customers Say?

Thousands of reviews from UK and EU shoppers suggest the following patterns:

  • Men’s Outerwear: “I normally wear a large but had to size down. The cut is generous and there's space for a fleece underneath.”

  • Women’s Rain Coats: “The sleeves are narrow and shoulders snug — I recommend sizing up if you want layering room.”

  • Trousers & Thermals: “Fit was perfect, true to size and great for walking.”

According to Tellar.co.uk's Sizing Review Hub, this is consistent with brands offering outdoor-functional fashion, where practical layering space is built into jacket sizing.


UK vs French Sizing: What’s the Conversion?

Aigle garments are often labelled in FR/DE sizes, which can confuse UK shoppers. For example:

Aigle Size Label

Women (UK)

Men (UK)

36

UK 8

XS

38

UK 10

S

40

UK 12

M

42

UK 14

L

44

UK 16

XL

However, these conversions aren’t always accurate depending on body shape. Many customers find the chest and sleeve dimensions to be narrower than expected, especially in tailored styles.

🔍 That’s where Tellar.co.uk steps in — we cross-reference your actual body measurements with how Aigle garments fit in real life, by garment type, not just label.

Key Tips for Buying Aigle Clothing

If you're shopping online or in-store, here are a few practical tips for choosing the right Aigle size:

  1. Measure yourself properly — especially chest, waist, hips, and sleeve length.

  2. Don’t rely on label size alone. A French size 38 may not fit like a UK 10 in every style.

  3. Account for layering. If you're buying outerwear, you may need to size up or down depending on how many base layers you’ll wear underneath.

  4. Read the fabric composition. Items with elastane or stretch panels will fit differently than rigid fabrics.
