The Buffalo Active Shirt is a unique fleece-lined garment, designed as an all-in-one base-layer and outer jacket. It's ideal for a multitude of outdoor uses, including hill walking, trekking, winter climbing, skiing and general outdoor activities. When compared to their Mountain Shirt, the Active Shirt benefits from a softer and quieter outer fabric, as well as a more muted colour.

Buffalo originated this one-layer system in the late 1970's, to replace the numerous layers often worn by climbers, fell runners and hill walkers in winter conditions. It comprises a lining of insulating pile fleece, with a functional and water-resistant shell outer, producing a garment that is completely windproof, lightweight and amazingly warm. It is also highly breathable and extremely efficient at transmitting moisture vapour.

As unconventional as it sounds, the Active Shirt is designed to work most efficiently when worn next to the skin. In this way, the pile fabric wicks moisture away from the skin more rapidly, where it is then dispersed to the outer fabric to evaporate and keep the body dry and free from chilling. Side zips have been fitted, not only allowing access, but to adjust for ventilation, enabling the user to regulate their body temperature on the move.

Buffalo Systems are dedicated to producing clothing for the professional and committed outdoor activist. All Buffalo products are rigorously tested through an entire season of Scottish winter and often longer. All components, from zips to thread, are of the highest quality and are equally tested.

Sizing: Buffalo have designed the Active Shirt to be a very close-fitting garment, to ensure maximum performance. Strictly speaking, the looser the fit, the less performance you will get. We recommend you measure your chest when completely expanded, and choose your size using this measurement. The Active Shirt is a mid-length top, which finishes at the top of the thigh.

  My wife and I have just returned from 4 days in Iceland, where we wore the Buffalo System Active Shirts and Buffalo Systems Special 6 trousers, my wifes had to be bought from Cotswolds because you do not have coloured tops and she did not fancy the slate colour. We wore the tops and Special 6 trousers in all conditions including -3oC and wind speeds in excess of 50 mph, they performed excellently and will (infact did) recommend the trousers and tops to several people while we were in Iceland. As it says in the leaflets you need to wear only underwear underneath and nothing else and we were comfortable at all times. We went from outside walking in negative temperatures and high wind, to inside the car and the tops and trousers performed excellently. We were at no time too hot nor did we feel the cold or wind chill on anything except our faces. We would both not hesitate to recommend the Buffalo system to anybody that is involved in any hill walking type of outdoor activity.

  The Buffalo Active Shirt is a well made and very comfortable item of kit. It's light weight so if you are out hiking and get too hot just stuff it in your day sack. If you wear it next to your skin you don't need a t-shirt. Good all season shirt.

  I have not yet fully tested this jacket, as I have yet to take it skiing in the Alps. However, I recently followed the advice of the manufacturer, Buffalo Systems, by wearing the garment next to the skin in near freezing temperatures. Despite other adverse weather conditions, including high humidity and a reasonably strong wind, I felt warm and comfortable; I could not feel the elements at all! I am impressed with the comfort (42 inch chest choice was perfect for a chest measurement of 41-42 inch) and happy that I have invested in something that will last years. It looks good too (says the girlfriend). Obviously a quality jacket that deserves the trust of an experienced wood-lore craftsman such as Ray Mears.

  My New buffalo active shirt arrived today and what a pleasant surprise it was. This top has the rip-stop fabric, unlike my trusty old version (the Mountain Shirt). At first I thought it would be a bit noisy, but it is almost as soft as the old one. The best thing about this top is that the zip on the front pocket does not get caught up in the flap that covers it, as it did on the old one. This was the only annoying thing about the previous top, so it is nice to see that the rip-stop material being a little bit thicker has stopped this from happening. Apart from that the top is still as good as it always was and will keep you warm as toast as long as you follow the garment guidlines. This time I purchased the Slate colour, mainly because my daughter was fed up with seeing me in green, but I'm very pleased I did as it looks great. So get your wallet out it will be the best £115.00 you will ever spend.
