I have the jacket and pants with the lightweight, waterproof liners. The temps they claim are a bit extreme, in my experience. Having said that, I've driven in full Kevlar through the Ozarks in July. When moving you will be comfy. The mesh lets the wind flow almost without restrictionl. The liner adds the protection against the rain.
I also wore this suit from New Orleans to Vegas in October. It was 100 degrees going through Texas and I was as comfy as I could be while moving. Of course, any time you stop it gets warm but while moving I was comfy.
The way home was chilly, 34 degrees in AZ and I had the liners in and a gerbings jacket. It was comfy. Make sure you get measured and if you have questions, call them. You will most likely talk to the owner, Wayne, who always seems to be available to answer questions.
I think the gear is better in warm climes vs. cold but I'm pretty happy with my investment. The armor is very well placed, including chest armor and the gear is durable!! I laid my jacket on the muffler and melted one of the zippers on the arm. The Kevlar didn't melt but the zipper did. Wayne got the jacket fixed and back to me in less than 10 days and was responsive to all my questions.
I hope I never fall but if I do I think this gear will protect me as much as can be expected.
I have only been riding for a year so take this opinion with a grain of salt. I don't see myself having to purchase gear anytime soon.
Hope this helps,
