Mens Heavyweight Bison Jacket

(7 customer reviews)


Our warmest wool garment. Made with our specialist heavyweight wool fabric woven from fleeces of our own Merino sheep. A naturally insulating, breathable and resilient overshirt that provides protection in all conditions day in, day out.



A comfortably fitted four pocket wool jacket designed, grown and made in Britain.


We created our specialist fabrics with one of the oldest family mills in Yorkshire, an area steeped in wool history and knowledge. The Bison’s was developed to offer even greater durability and warmth whilst maintaining wearer comfort whatever the activity.


The soft underside of the fabric was something we worked particularly hard to create with the mill. It not only provides unrivalled next to skin comfort but also increases the amazing thermoregulatory ability of the wool further by trapping air in the fabric and insulating the body. Keeping you warm when its cold and cool when it’s warm. At the same time the durable outer side of the fabric enhances wool’s natural water repellence to provide weather protection.


For use in the field Merino wool is odour resistant and silent, making the Bison easy to care for and useable straight from the woods to the home.


The Bison is a naturally insulating, breathable and resilient jacket to be used in all conditions day in, day out.

    Fantastic jacket! Warm, breathable and durable, surviving everything that can be thrown at it on the farm.

    My Bison arrived yesterday, the day after ordering. I have been following Herne since a visit to the flock and have waited for this ever since.

    The jacket is fantastic, it is soft and fluffy inside, rugged and smart outside with all the best qualities of 100% wool. This is my go to jacket for most situations and when under my ventile jacket allows me to stay warm in the worst weather in North Scotland. The provenance helps me feel good about owning the the jacket.

    Some things make one smile, ever more important today, so when I use my Earth coloured Bison jacket I smile!
    So comfortable, so practical, so much better than all those synthetic clothes, why would you not own one for life?
    Love it!

    My Bison arrived just 24hrs after placing the order, it’s not left my back since it landed.
    Quality is second to none, super soft feel, lovely and warm, I normally take a 44 inch top, and was a little confused which size to go for, but went for an xl on the basis I like to wear a jumper etc under things, I’m glad I got this size, it’s got all the room I require without feeling big or baggy, I probably could have got away with a large but the XL just gives me a few more options.
    I suspect it’ll take many many years of bashing and still be a firm favourite.
    Great product, speedy service, and lovely to support British enterprise at its finest.

    Yes it’s me again – I ordered the Bison jacket after I fell in love with the Stag shirt.

    An absolutely fantastic piece of kit for trekking around the hills. Protective, hard wearing and warm.

    Very highly recommended

    I ordered this jacket for my husband and he is a big fan! Great fit, very warm, and it looks outstanding on him… if I do say so myself! I firmly believe everyone should own a Herne piece. Whether you’re ranching, farming, or going out on the town they look and feel great. They are a new staple item in our wardrobe!

  7. Keith

    Superb bit of kit! The quality of the homegrown wool, the skill and detail in it’s construction & sewing here in the UK, the thoughtful, positive nature of the whole approach to this way of living/trading, plus it keeps you warm and looks the bollox……..what’s not to LOVE!
    My Bison jkt and Stag shirts are head and shoulders above the Japanese and US wool garments i have tried too.
    Thank you Herne, fantastic 🙂
