Original stirrup pants
I've been buying these running tights for over 30years. They last forever (I have a pair over 10 years old) I don't buy anything else. I use them for running in any cold weather. When it's below 20, I just add an underlayer. I can't praise them enough. I'm 6' 2" and 160 lbs. and I get the medium long size and they fit very well. I hope you'll give them a try.
Saving my receipt
I don't know how many pairs of these i've purchased over the decades. i started buying them in the mail-order days... That I keep coming back tells you a lot. I like to have two pair on hand all the time.
The pair I just received replaces the *newer* of the two I had. That one -- the one i replaced -- was less than a year old when the front crease stitching failed. i didn't have the receipt, so i just put up with it until a week ago. I'm saving my receipt on the new ones. Hoping that was just a one-off.
