Last year I was fortunate enough to buy a Motoport
https://www.motoport.com/shop/ full suit in Kevlar Air Mesh from one of the members here who had to quit riding due to back and neck issues that were aggravated by riding. This was a custom- made, custom-fitted suit for him but after verifying a few measurements, he and I were very close in size and a was fortunate to purchase one of the best riding suits available for a great price. Both the Marathon Air Mesh Jacket and the Ultra II Air Mesh Pants are made with the Kevlar Air Mesh fabric. These breath extremely well, especially the jacket.
Note that I have had an Aerostich Roadcrafter 2-piece suit for 10 plus years and really like it...but after buying a 2021 RTL last year, with its great wind protection, I was too hot in the 100-plus heat index summer days of eastern KS and looking for something that was cooler in these conditions. I had ridden with the Roadcrafter on my Ducatis, and on my 2009 Spyder GS and was able to survive in the worst conditions...but they didn't have the wind protection of the RTL. Above 90F, the Roadcrafter was too hot, even when moving.
The Motoport Kevlar mesh, for me is much better in the worst of the KS heat and humidity vs the Roadcrafter, and, probably offers better crash protection than virtually any suit available. It's not as trim and close fitting as the Roadcrafter, but breathes and cools much better in the heat, and offers room for the waterproof and/or insulated liners as well. It also has a large coverage of well positioned armor padding that stay where it should.
Now I typically wear the Roadcrafter when it is cooler, but get the Motoport Kevlar mesh suit out when hot and humid. BOTH are great suits with great crash protection (I think the Motoport would be the one I would want to be in if I knew I was to be in a crash), great quality, and will stand up to years and years of heavy use. As a matter of fact, we are planning to get a Motoport suit for my wife since she likes to ride in warmer rather than cooler conditions.
There are some bargains out there in top shelf riding suits if you are patient and don't be afraid to look in the "For Sale" section in this forum. It worked out well for me! In any case, having several types of riding suits to chose from not only offers much improved crash protection and safety, but also lets you better dress and prepare for the riding conditions at hand.
Thanks,
Rod
