SKU: N/A Categories: ,


The McNair finest grade virgin heavy weight merino mountain shirt.

Wear it instead of a jacket when you think you need a shell. Use it as a mid-layer on the very coldest days. Wear it out in a blizzard, and watch the snow shake off it, wear it down the pub or just to fall asleep on the sofa watching telly.

The luxurious heavy weight virgin merino wool is water resistant, wind resistant, doesn’t hold odour, is sustainably sourced, tougher than you’d think and very, very warm.

We’re very proud of the hidden baffle that sits beneath the buttons for extra wind protection.

  1. :

    Thank you for the amazing shirt! Incredible quality and they look, feel and fit great – thank you so much!

    My shirt arrived early and it’s fantastic just worn it the first time today and really keeps the wind out and keeps you warm. Thanks to Natalie and Charles for making sure I got the right fit and Irana who has made it so well.

  3. :

    Outstanding customer service from Natalie! Thank you very much for such an amazing shirt! I was dubious about the shirts merits as a replacement to an ordinary ski jacket. But I was proven wrong when I got on the mountain. With 2 base-layers underneath I could wear the shirt without feeling the cold very often (perhaps on the chair lift back up). And when it began to snow harder or get colder I just grabbed a thin outer jacket from my backpack and chucked it on over the top. One thing I would note is that the top button is very tight around the neck, but I tended to leave the top button undone and wear a neck warmer anyway so it wasn’t that big of a deal. Thanks again to Nat for her help with choosing the shirt and Irina who made it for me!

    Thanks so much for getting the shirt over to me so quickly, it fits perfectly and is lovely (exactly as my other shirts). The level of customer service/care is wonderful and the quality of the product is second to none!!

  5. :

    The shirt arrived yesterday and it is even better than I expected, thank you! Can’t wait to get it out in the hills.

  6. :

    Simply the best! I dealt with Natalie via phone from UK to Australia. She set me straight vis -a-vis measurements and my new black made-to-measure merino wool shirt is a work of art! Finest workmanship and beautifully crafted needle work OI have seen in a bespoke shirt. Wonderful. Cheers, Ben Anson

    As one of your customers states, keep doing what you’re doing. You have a fantastic product.

  8. :

    Had mine a few weeks now and glad I visited the workshop as I fell between two sizes. My wife, the little purple oompah loompah picked it for me few days later and hardly a day goes by without me finding an excuse to wear it. Love it and I have also been asked by youngsters (who probably think I’m cool!!!!) if I have anything to do with a celebrity snowboarder called McNair! Had to come clean, but love the shirt and the warmth! Will be coming back to get my little purple oompah loompah measured up sometime soon!

  9. :

    I had my shirt made to measure, Natalie phoned to check the measurements and I ended up with a perfect fit. The best made, warmest shirt I have ever had – so great that my wife said go and order another one !!! It’s also brilliant to feel that you supporting an artisan British industry and product. It feels like it will last forever.

    “We’re both very happy with our shirts – and excited to use them next week! The quality oozes out of them and I imagine I’ll shortly have a number of very jealous friends…

    Thanks for taking the time to help me with everything at such short notice, it was much appreciated.”

    “Just wanted to say a quick thanks for getting my shirt out to me so quickly. The quality is absolutely fantastic, it really is a lovely bit of kit.”

  12. :

    Looks and feels amazing. This will be coming with me to the X-games in Aspen tomorrow. Thank you for the swift delivery and polite and simple nature of getting this to me. I am sure this will keep me warm in the cold temps of Aspen and then Breckenridge. It’s a breath of fresh air to purchase something that is actually made in Britain and made properly.

  13. :

    Absolutely superb!! I read about the shirts in E & T magazine and thought I must have one, so technically precise, so warm. Tips hat!

    “Just back from Skiing in La Grave. What a pleasure to wear the “worlds finest mountain shirt”.  The shirt draws on the heritage and skill of the West Yorkshire textile processing industry which is recognised as a world leader in wool. As a fourth generation wool dyer and finisher I am a proud supporter of this shirt. Congratulations to the team at McNair for creating a superb product. Get one !!”

    “My shirt arrived today, love it and it’s a perfect fit. Please pass my particular thanks to Josie for her skill and time in putting my shirt together… My wife is a textile design teacher for her sins and she tells me it was not an easy piece to stitch together… not the easiest material to work with lots of layers and tricky technical details all really well executed… so I’m now even more impressed with it! Thanks to all involved….I’ve a feeling it won’t be my last McNair shirt…the new blue colour looks nice.”

    “Hi, visited your Mill this morning, AMAZING, I was measured by Natalie and I have placed a Custom Order. I was treated like Royalty, now when my sons want one each, I have no reservation in driving and letting them have the same experience, Top of The World!”

    “…very quickly it became my go to garment as it got colder. Buttoned up and collar up it keeps out the harshest winds, but the shirt isn’t bulky like a down jacket, or something that needs to be shed as soon as you get into your favourite resort bar!”
