SDooley,
I know the Texas summers well, 33 years in Texas. Now I’m in Spain also with brutal summers… I’ll take the heat and misery of a Texas or Spanish summer vs the snow and rain… but that’s just me. 
I have never tried Rapha products I wanted to but have had a hard time trying to find online stores here in Spain or Europe that carry their products. Shipping from the USA is tricky i.e. potentially costly as the VAT(value added tax) plays a role and it can be anywhere from 21-30% cost increase.
I learned the hard way on a deal for a Castelli Alpha Jacket on sale from Colorado Cyclist but thanks to VAT I lost all my sale advantage 
but the jacket is still a killer at cost.
