Contrary to other reviews, I don't think these are good for wind protection in cold weather - 30 degrees. Good product, good fit, but New Balance should provide a better description. This is part of their lightning dry product line, which means it's thin and meant to breathe. While these will not meet the need for my intended use, I will keep them for the upcoming 50 degree weather. But I went out and bought a pair of Sugoi Medium weight for the cold weather - not their sub zero but the one that's a little lighter - they have a nice lining for warmth.
If you are looking for a quality running pant/legging, with good fit, compression and breathe-ability, this product will certainly work.
Would also work well for a moisture wicking base layer underneath running pants or sweats, if you need compression or base layer for the cold.
Size is true to New Balance sizing.
