It’s only natural – for those of us who call the Northern Hemisphere home anyway – that our thoughts (and conversations) turn to inclement weather this time of year, when pockets of sunshine become harder to come by and the threat of a downpour a daily worry. Saying goodbye to sunny days and welcoming autumn is a little easier, of course, if you’ve made the necessary sartorial preparations. Which is why it’s particularly fortuitous that Japanese brand nanamica has just joined MR PORTER’s roster.

The label, founded in 2003 by Mr Eiichiro Homma, has a singular mission: to make stylish but eminently practical clothes. “Some people who cannot stand the winter chill choose to wear the latest down jacket to keep warm, while others put up with the cold just so they can wear a vintage coat that looks stylish,” he explains. “We want to make clothes that satisfy both of those whims; in other words, the perfect casual wear that doesn’t compromise on function or fashion.” Sound good? We thought as much. Here’s just a handful of our favourite pieces from the collection so you can start to formulate your plans for the season ahead.

If you thought the classic navy blazer couldn’t be improved upon, think again. Made from the brand’s proprietary Alphadry fabric, this smart-meets-casual iteration is wrinkle-resistant and quick-drying, which is particularly useful in case you get caught in any of those aforementioned downpours while on your way to work.

Padded with performance-grade Kodenshi down-like filling, nanamica’s gilet offers a lightweight layer of warmth and comfort on chillier days. Don’t be shy of the shade – if you need some pointers on how to wear orange (aka the colour of the season), we’ve documented its rise and produced a brief primer here. You’re most welcome.

Where were you when the fleece returned to the stylish fold? If you’re only just joining us, this camel-coloured version is an excellent jumping off point. It’s made from Polartec fleece, the gold standard for all things outdoorsy since the 1980s, and therefore feels thoroughly true to the garment’s retro roots.

Another option for crisp conditions, this considerately cut (see the raglan sleeves and well-proportioned rollneck) sweater is crafted from Dualwarm tech-jersey – a super-soft ponte-like fabric that by some alchemical feat converts body moisture into heat to keep you toasty warm. Genius.

There are countless important details to note about nanamica’s raincoat, the most salient of which is that it’s tailored from cotton, so it satisfies the smart-enough-for-the-office requirement, but is backed with Gore-Tex, which means you won’t arrive damp when you get there. We’re also big fans of the so-called “soutien” collar, which can be worn both down and turned up to protect against windchill.
