Fabric for manufacture - cotton, leather, textile, or hybrid?
Textile, breathable
Length of jacket short or touring style?
Closer to the touring Length
Consider the wearer of the jacket is riding a well faired bike that needs more ventilation.
Any other specific design features? E.g. Additional mesh panels for ventilation
Possibly mesh panels in the front of the jacket
Is ventilation required, placement of ventilation?
Yes, vents in arms, front and back, as the ST's disperse a lot of the air so need plenty of opportunity to get sir into the jacket
Does the jacket need to be waterproof? Removable or permanent waterproof lining
I would be happy with a removable waterproof lining, or the jacket being waterproof with big vents than can be zipped up
Does it need to provide protection from the elements when the temperature drops to 5 degrees?
Yes
Does the jacket need a thermal lining?
Not a must for me, as I wear a vest under my jacket
Should the thermal lining be removable?
Yes
Does it need to be suitable when the temperature is over 30 degrees?
Yes
Apart from the above, I would like well placed reflective piping on the jacket to go with the orange for visibility, and decent pockets.
What I have in my head at the moment
