These shorts are long enough to reduce or prevent friction on your inner thighs and legs during normal or extreme activities.

I buy these here, because my local department store is always out of "Mediums". These have more spandex than normal underwear, but aren't up to the "Bicycle Shorts" standard.

These have a good deal of support, and the right combination of cotton and spandex.  I started off with 8 pairs, and two years later they are still wearable.  The material near the center of cross seams is starting to develop small holes (size of a cigarette burn) on some pairs after aproximately 73 wash cycles.  (365 days * 2 Years)/10 Pairs = 73 washes.

The elasticity of my oldest pairs is almost identical to the new pairs I just purchased.  I'm amazed that these hold up so well!

My oldest pairs are still wearable, but my mama would have made me throw them out by now 'coz I might get hit by a car (and what would the Doctor at the hospital think if I had holes in underware!)  I'd also recommend going with "Black" for the obvious "Stain" reasons.

If your thighs are getting bigger (from gaining weight or muscle mass), and they are staring to rub in places that didn't used to make contact, these are an excellent solution.

Pros:  Reduce Thigh Friction. Have a fly. Fairly Durable (Survive 75 Wash cycles and are still wearable).  Reasonable amount of support and Spandex.

Cons:  10 pairs will set you back $100 (if you wear these exclusively -- but they'll last you 2 years if you do laundry once a week).
