We got this to test in both hot and humid weather. The dissolvable yarn is essentially soft mesh fabric which is not see through. It's incredible how much air moves through this shirt. Where other shirts have vents this entire shirt is a vent.

Perhaps the coolest (pun intended) new product is the Motive Jersey, which uses a dissolving fabric to create a massively ventilated garment

The motive allows air to go through the fabric, circulate and exit, bringing my body heat with it. And it takes so little wind or motion to get the process going. Even if I get out of the saddle quickly, there's a bit of a rush of coolness on my back.

Club Ride makes great jerseys for people who don’t want to scream “I’m a mountain biker” everywhere they go, although their brand is synonymous with mountain biking, so you’re still kind of making a statement to other riders. Overall, the Motive is a really cool and breathable jersey for summer riding.
