Winter is coming and i saw these 32 Degree Heat Men’s Base Layer Pants for $7 and i bought them and tried them out! They are very flexible and comfortable. good for and added layer for heat generation. It fits my thick thighs well. Medium size I got did not fit my waist very well, it was a tad loose. It may be better on a 33+ waist band for Medium size.
They also sell them on Amazon: http://amzn.to/2zqgNmi
