What Is Sizing Like at Save the Duck?

By Ella Blake — Fashion Stylist | Tellar Fashion Hub — Always honest, unbiased & unsponsored

Save the Duck runs true to European sizing — so if you're a UK 10, you'll want a Small — but because their outerwear is designed to layer over knitwear, the cut has a little more ease than you might expect from an Italian brand. That said, I'd always recommend sizing down if you're between sizes and planning to wear it over lighter layers.

I discovered Save the Duck a few winters ago when I was looking for a really good puffer that didn't involve goose down. I'll be honest — I was sceptical. Would the insulation actually hold up? Would it feel cheap? Reader, it did not. My MEGA jacket has been on roughly forty-seven dog walks, two ski trips and one particularly grim rainy fashion week day, and it still looks brilliant. But I did get my size slightly wrong the first time round (I sized up on instinct and it was too boxy), so let me save you the same mistake.

A Bit About the Brand

Save the Duck is an Italian brand founded in Milan in 2012 with one clear mission: beautiful, high-performance outerwear with zero animal-derived materials. No down, no fur, no leather, full stop. They use their own proprietary insulation technologies — PLUMTECH®, FUSEFIT®, RECYCLED — to replicate and often outperform traditional down. It's a genuinely impressive offering, and the jackets have a sleek, clean aesthetic that works equally well on a city street or a mountain path.

The brand has grown enormously in popularity in the UK over the last few years, and rightly so. If you're looking for serious warmth without any of the ethical complications of traditional down, this is one of the best options out there.

Always check the individual product page on the Save the Duck website, as sizing can vary slightly between collections and jacket styles.

How Does the Sizing Work Across Different Styles?

Save the Duck's range is primarily outerwear, but the cut and fit varies more than you'd think between styles. Here's what I've found — both from personal experience and from styling clients:

Puffer Jackets (IRIS, GIGA, MEGA): These are the brand's bestsellers and they fit true to the EU size chart. They're cut with a semi-fitted silhouette — not boxy, not super tailored. If you're between sizes, go down. The padding gives enough volume without adding unnecessary bulk.
Long Puffer Coats: The longer styles, like the NIKOLPARKA range, tend to be slightly more generously cut to accommodate layering over chunky knitwear. I'd say these fit about half a size larger. If you're a UK 12, you can comfortably go for a M.
Lightweight & Transitional Jackets: The ELSIE and PENELOPE styles are lighter-weight and cut closer to the body. These run slightly small — I'd suggest going up a size if you want any ease through the shoulders or if you have a fuller bust.
Hooded vs. Non-Hooded: The hood styles add a little extra volume around the neck and shoulders. Nothing dramatic, but worth factoring in if you're buying online without trying first.
Children's & Unisex Styles: Save the Duck also does a strong unisex range. These run true to EU sizing but are cut straighter through the body — if you prefer a more feminine silhouette, size down one.

My Honest Fit Tips for Save the Duck

Measure your bust and check it against their specific style's measurements — the brand lists measurements per style on their website, which is genuinely helpful.
If you're buying a puffer to wear over a heavy-knit jumper or thick fleece, I'd go up a size. For wearing over a shirt or thin top, your usual size is perfect.
The jackets have a slightly longer body length than some competitors, which is great for keeping your lower back warm. Worth noting if you're petite — you may want to check the hem length before ordering.
Their sizing is consistent across seasons — if you've bought Save the Duck before, you can trust your previous size will translate.
