The tights look pretty good, but for some reason I ordered an M instead of an S, and it was loose for me. I am usually an S size, but I thought that I needed a larger size with other base layers that I would be wearing underneath. I reckon in hindsight, I would have been better off with an S. I am keeping it anyway because it has really grown on me. It is a comfortable pair of tights, loose fitting, though a little long for me (5' 3", 54kg). It has soft fleece insides and a smooth outer side, and a tiny hidden pocket on the inside which is quite handy for keys when I go for walks in the autumn and winter time. The slim sleek design is preferred and I can wear it indoors and outdoors as it doesn't look like a pair of frumpy track pants that people wear to sleep. t have tested it out in about 10-15 degrees celcius and windy (about 24 knots according to weather forecasts) conditions. It works pretty well, and I had a pair of base thermals underneath. I went for a walk in these cold windy conditions and was perfectly warm and comfortable. I would love to buy another pair, in size S next time.
