So I'm looking into making a pair of shorts to trail run in and I've noticed that on every rainy trail run only the front of the shorts get wet. The back is totally dry. So it got me thinking to make the shorts with a waterproof material in front and a quick drying material in the back.

Anyone have experince with this? Will I over-heat with the front not being able to breathe? And that brings me to my next and most important question of what materials to use? Silnylon in front M90 in back... I'm lost on what materials to consider.

Thanks!

If you are going for the absolute lightest design I would vote for black CT1K.08 in the front with 2012 SevenD in the back. The cuben will quiet down after a bit of use and it should be opaque enough to hide everything you might want hidden.
