Not just for cooling
I have been useing the LD shorts for 3 years now.
Before I got them 150miles ws killing me.These shots took me out to 650+ a day and ready to get back on the bike the next day.
These shorts made a huge diffrence in my riding comfort.No seams to rub you raw.
If I had to guess the LD material is at the minimun of twice as thick as all the other shorts you find.Very heavy weight and keeps you from vibrating around.
Just my 2 cents but some of the best money I have ever spent.
