"One of the best bits of kit I have ever bought. Those who fondly remember/still uses the 'Norgie' Norweigan army shirt which proved so popular with squaddies in the 80's-90's it ended up being British Army issue, will absolutely LOVE this 21st century equivalent which, unlike the Norgie, doesn't get drenched when sweating. Perfect for any outdoors activity, be it humble dog walking or out in the wilds. I cannot stop wearing the top about the house. I wore the bottoms on a very early morning, cold and damp hill walk as 1 layer under trousers and had a very fast/steep ascent to do; I had to throw off my jacket but my legs never got sweaty, which I thought was quite incredible. Buy 2 sets because your wife will want you to wash the top occasionally, so you'll have to take it off. I also must mention the most excellent customer service from Arctic outdoors."
