the thing is rain gear does not breath .. so you bast in your own juices... not a nice feeling... everyone opens there wallet when it comes to a machine but when it comes to good WATERPROOF BREATHABLE clothing... then everyone counts there pennies... lol
rubber boots is the only thing that i wear that is not breathable cause wearing mx style boots is not the thing for quad pleasure riding and no one makes a good high breathable boot like a quality rubber boot...
there are boots for winter that have a gore tex breathable membrane but for summer they are too heavy...
It does really seal in the flavor. But it works great rain or shine. I have soaked through supposedly breathable waterproof gear so often I quit spending the money on it. And that was hiking in the back country and not getting splashed by mud puddles. Breathable and waterproof should not go in the same sentence. In order to be breathable clothing requires venting of some sort whether that is in between the fibers or actual vents. That only makes them water resistant and not water proof.
