I love the Etxe Ondo line for warm weather, either sleeveless or short-sleeve. The silky fabrics fit close & wick well, and the mesh panels give great air-flow to cool. I overheat very easily, & have learned through trial & error to steer clear of all the great-looking jerseys that have sublimated designs. The fabric has to have a tight weave to give sharp outlines to the designs, hence they don't breathe as well & I cook in them. Don't worry about the inside seams bothering, because the finish work all through the line is exquisite.
