What Is Sizing Like at Napapijri Menswear?

Napapijri runs slim and on the small side of European. It's cut for a leaner frame, so if you're broad through the chest or shoulders, or you plan to layer under the outerwear, you'll usually want to go up one size from your normal UK fit. Below I'll break down exactly where the sizing catches people out and how to get it right first time.

Napapijri's fit, tier by tier

Napapijri is an Italian outdoor-lifestyle brand, and it's cut like one — trim, close to the body, and built for movement rather than draping. After years of fitting men into it, here's where the sizing lands:

T-shirts and sweats — fairly true to size but slim through the body and arms. If you like a bit of room, size up; if you want that clean, close European look, stick to your usual.
Outerwear (the Rainforest and Skidoo) — this is the big one. The icon jackets are cut slim and slightly short, so a jumper or hoodie underneath your usual size will feel tight across the back and shoulders. For layering, go up.
Knitwear — runs true but narrow in the sleeve and hem. Broader arms will feel it first.
Trousers and joggers — European sizing, so a UK 32 waist can feel closer to a 31. Try the next size up if you're between waists.

A fit I got wrong (so you don't have to)

Confession from early in my styling days: I ordered a Rainforest jacket online in my "usual" large without a second thought. It arrived looking sharp on the hanger — and then I tried to wear a mid-weight hoodie under it and couldn't get my arms above shoulder height. Straight back it went, swapped for an XL, and the difference was night and day. The win came later with a client who insisted he was a medium in everything: we sized him up to a large Skidoo, layered a fine-gauge knit underneath, and it completely changed his silhouette. The lesson both times was the same — size Napapijri for the layers you'll actually wear, not for the empty jacket.

How to nail your Napapijri fit

Decide your layering plan first. Base layer only? Stay true to size. Hoodie or knit underneath? Go up one.
Mind the length. The jackets sit slightly cropped, so pair them with mid-rise trousers rather than anything that stacks at the ankle — it keeps the proportions balanced.
Check the sleeve. This is where slim brands trip up bigger arms. If the cuff pulls, the whole jacket will feel a size too small even when the chest is fine.
On trend right now: muted earth tones, technical-but-clean outerwear, and that "quiet outdoorsy" look — Napapijri sits right in the middle of it, which is exactly why it's having a moment again.

If Napapijri doesn't fit you, try these instead

No single brand fits every body, so here's where I send men depending on their build — with a note on how each one sizes up against Napapijri.

High street

Uniqlo — the most consistent sizing on the high street. Their BlockTech parkas are a genuinely good, cheaper stand-in for the Rainforest, and their fine-gauge knits are the perfect mid-layer to wear underneath.
COS — go here if you find Napapijri too slim. The cut is relaxed and boxy, so you get that modern, roomier silhouette without sizing up.
Marks & Spencer — the safe bet for broader builds. Generous, reliably true-to-size chinos and lambswool knits that make an easy base under technical outerwear.

Independent & boutique

Fjällräven — roomier and boxier than Napapijri, so you can often size down. The Greenland jacket is the go-to if you want function with a heavier, more utilitarian feel.
Rains — Danish rainwear cut deliberately oversized, so size down one from your Napapijri size. Clean, minimal, and brilliant for wet British winters.
Universal Works — British, workwear-influenced, and cut slightly more generously than Napapijri. Great overshirts and relaxed trousers with real character.

Designer & luxury

Stone Island — the natural step up. The slim technical cut is close to Napapijri's, so your size usually translates straight across.
C.P. Company — Italian outerwear that's slim through the body just like Napapijri, so size up for layering exactly as you would there.
Moncler — beautiful down jackets, but they run distinctly small and slim. Plan to go up a full size, especially on the puffier styles.
