Great tights

    I love wool for a base layer. I've used these ice climbing and backpacking and they've handled the range in temps really well. Keep me nice and warm when it's cold, and don't make me too hot when the heat rises and body gets warm from hiking.


    Awesome Bottoms

      I am a wool fanatic and these more than pass the test. I have never had any Ibex stuff before but these pants have impressed me. They are very soft and well made. I highly recommend these bottoms.



        My first experience with merino wool was about 3 years ago and it was with these tights and all I can say is that they are amazing! I have worn them probably about 100 times and they are still holding up, I usually just wear these and my ski pants while skiing and they are perfect but on really cold days 10 degrees and below I have to put on a heavier layer.
