This is the comparison I've been looking for before pulling the trigger on a Motoport.
Is there a difference in overall comfort (fit), temperature comfort, and convenience? I understand the theory behind the difference in protection (not sure if it really makes a difference in practice).
Motoport is custom fit both jacket and pants. So that beats off the rack right there for most of us. A proper fit with comprehensive armor is theoretically and practically ideal for minimizing injury. The materials they use as I understand it are some of the best you can utilize for the protection we require for the type of accidents we will encounter. The options for material (Kevlar mesh or Stretch Kevlar) armor, zippers, vents, pockets, collars, etc. etc. are numerous and they will customize to suit you. I had a 3" wide mesh panel that zips onto the front zipper for added air flow on my stretch Kevlar jacket. I will not ride without their stretch Kevlar pants. Any weather any distance. Armor from hip to ankle. The jacket I use in cooler weather and on road trips. I am saving for the mesh 'shirt' they make. My $100 mesh jacket is arguably laughable in comparison but far better than a t-shirt when riding locally in extreme heat. I also have a Vanson leather and mesh jacket that has decent protection but it doesn't flow enough air.
Thanks for giving me the opening to praise Motoport's many good features. Their price for a custom jacket starts at around $450 I think. In my opinion $1000 for some of the best riding gear you can own to help you survive a fall and slide is cheap insurance. I work in a level one trauma center. I'm no oracle and I know I'm sounding pedantic. It is simply very good gear for our sport. There is a long Motoport thread on ADV Rider and if you Google Motoport I believe you will find lot's of first hand reports about what I have stated. Use your imagination when thinking about what you want your gear to do for you, how it should fit and what modifications to suit your style of riding and weather you will typically encounter.
