Ilse Jacobsen Sizing Overview: Runs Generous in Outerwear, Slim in Shoes

Ilse Jacobsen sizing is generally true to size or slightly generous, especially in raincoats and jackets. The brand prioritises comfort, layering, and movement — which is great news for anyone tired of tight, restrictive outerwear.

Outerwear

Raincoats and Softshells: Typically run slightly large to allow for layering. If you’re between sizes, you may want to size down unless you like a roomy fit.
Quilted Jackets and Puffers: Also run a bit large but are designed with proportion in mind — longline styles can feel slightly oversized but still flattering.

Footwear

Rubber Boots and Slip-Ons: These are known to run small, especially in length. Many wearers go half a size up, particularly with thicker socks.
Sandals and Flats: Tends to be true to size, though narrow feet may find a looser fit depending on the design.

Fabric & Fit: Designed for Practical Living

Ilse Jacobsen uses smart performance materials that affect sizing and feel. These include:

Stretchable softshells for breathability and flexibility
Welded seams and PU coatings for waterproofing
Eco-friendly natural rubber in boots
Lightweight quilting for insulation without bulk

These technical choices lead to comfort-focused fits, especially in outerwear — making it easier to wear over jumpers, scarves, and thermals.

If you live in the UK or Northern Europe, this functionality is ideal. But it’s worth checking your fit carefully — particularly for shoes and boots.

What to Buy from Ilse Jacobsen

Ilse Jacobsen may be known for rain boots, but the full product line is impressively curated. Here’s what’s consistently worth investing in:

1. The Classic Rubber Boot (Rub15, Rub2)

Available in high and ankle cuts, these boots are a cult favourite. Waterproof, hardwearing, and shock-absorbent, they’re ideal for city commuters and countryside walkers alike. Size up for thicker socks.

2. Raincoats (Rain71, Rain203)

These softshell or PU raincoats offer a flattering silhouette without compromising on water resistance. Popular for everyday use. Slightly roomy fit.

3. Tulip Shoes and Slip-ons

Lightweight and breathable, these laser-cut slip-ons are perfect for travel. Go for your usual size or half size down if you have narrow feet.

4. Quilted Jackets

Great transitional pieces, often used as layering options under parkas or over base layers. Expect a generous fit, so you can size down for a more tailored shape.

Why Ilse Jacobsen Sizing Can Be Tricky

Sizing inconsistency comes from differences between European and UK sizing systems, combined with outerwear design flexibility. You might be:

A UK 10 in Barbour
A UK 12 in Rains
And a UK 10 or even 8 in Ilse Jacobsen raincoats

Which is why brand-by-brand comparison tools like Tellar.co.uk are essential.
