I have several pair of these, both new and some still around not so new. I think the strong point for these is the fit. I think the chamois is good, but not as good as some Italian designed shorts (but whose fit is too small.). These are my favorite by default and great value when on sale.
These tights are ideal in temperatures between 40 and 58 degrees. Totally satisfied.
Use for cycling, 3-75 miles ride. They have the right amount of cushioning without feeling very bulky. The length is perfect, comes to mid thigh (I'm 5' 1 tall). The material really wicks moisture away from you. Just the right amount of compression. If you are in between sizes I recommend sizing up.
