Buffalo Systems Active Lite Shirt - Slate


Weight: 560 g         15 reviews
The Buffalo Active Lite Shirt is a unique fleece-lined garment, designed as an all-in-one base-layer and outer jacket. It is a milder weather alternative to their Active Shirt, for when less insulation but maximum wicking is required. It's ideal for a multitude of outdoor uses, including low-level hill walking, trekking, climbing, mountain biking, running and general outdoor activities. The Active Lite Shirt benefits from a tougher outer thanks to the use of a mini-ripstop shell. This technical material is highly breathable, windproof and water-resistant.

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 Lite 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. Another option is to wear a breathable base layer underneath. 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 Lite 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 Lite Shirt is a mid-length top, which finishes at the top of the thigh.

  Smashing bit of kit, keeps you warm when static or doing low level activity, ventilation and moisture wicking keeps you stops you from getting too hot when on the move. Decently water resistant in case you get caught in a shower.

  I ordered this to replace one that I had damaged. I mainly use this jacket for when I take my dog for a walk and when I'm out with the camera as I do a bit of landscape and aviation photography in the mountains of Snowdonia. The pockets are the main reason I like the jacket as there is plenty of easy accessible storage for phones,lens caps,filters etc I also have the Special 6 for when conditions get colder. Both are great jackets. The price and delivery from Woodlore is great. I will use again.

  I’ve been using special six and mountain shirts for years, but wanted something lighter. Feels very different to the thicker shirts, very comfortable and lightweight. I’ve worn it to do the tour du Mont Blanc and it’s all you need! Brilliant service as always from woodlore.

  The service from Woodlore was perfect and the active lite shirt is the best bit of kit I have ever bought. I quite literally have not taken it off and it is made in UK. I followed the sizing instructions. Do not go too baggy in my honest opinion. What I have bought to go with it is a merino sleeveless T shirt and that is working really well. The vents make it super flexible and adaptable.

  Haven’t had it for long but so far I love this jacket. It’s warm with just a t shirt underneath. It’s light but wind proof and seems fairly waterproof although I haven’t experienced any heavy rain yet. Great to see its made in the UK. Very pleased.

  Have a Mountain jacket which is now 30 years old and a Super 6. Both are quality items for cold nights, anything about 6 or 7 degrees and they are a bit warm unless sitting in camp. The Active Lite shirt is a lot lighter and is a generous fit. It feels great on and is good for spring and autumn, still too warm for summer but I run hot when carrying a load. I never wear anything under the shirts or jacket and have always had them next to my skin, they work best that way and you are actually warmer that way from experience, especially when wet. Why four stars, well the price is high but that’s relative to the quality and so that’s not the issue. I find the new pertex a little shiny a bit like a Dr Who extra, and it’s not as water resistant (I don’t mind being wet in a sSuper 6) but the most annoying is it has no neck baffle. This is a bit gapey on the neck line for me and water runs down the gap... Buffalo are brilliant so minor point.

  This is an addition to my other Buffalo clothing, I find it always performs well. I have bought this for the milder weather knowing it won't let me down.

  This is the best shirt I have ever had in my life to keep me warm. Seriously not over judging the product but it really kept me warm in very cold weather. Moreover, if the weather is partially cold it is possible to open the sides to let some cold air inside. I give it 9/10.

  Works very well, would recommend. I have only used this a few times now, but it seems to work in an impressive range of temperatures. Excellent for mountain biking on days that start below freezing and warm up. Also great for casual pace xc ski touring below freezing. I would rate it five stars if there was some sort of highly breathable fabric that offered some skin protection at below freezing temps under the side and neck zips. With a base layer and shell system, you have some protection against direct contact between skin and cold air when the pit and neck zips are open. Since the Buffalo System shirts are designed to be next to skin, you lose that.
