The Tour Master Coaster Air II, what's this, a top-grain, 1.2-1.3mm drum-dyed leather jacket with many of the usual features, for a retail price of just US$ 207 (about 6315 THB)? It has a zip-out liner with Polyfil insulation, and to really fine-tune the temperature range the sleeves can be zipped off. There's also removable CE shoulder and elbow armor, and an action back.
Like many motorcycle jackets the Tour Master Coaster Air II zips up securely, and has the usual standard pockets. What really sets it apart is that, in addition to its price, it is fully vented with zippered inlet vents in the chest and upper sleeves, and a pair of exit vents in the rear for flow-through ventilation. The chest vents (just above the horizontal stripes) double as pockets. Remove the liner, open all the vents and the jacket truly flows a lot of air. Amazingly, even the zippered hand pockets have a mesh liner and can double as vents. The Tour Master Coaster Air II jacket is especially suited for tropical countries like Thailand. I do not recommend using the hand pockets as vents if your are carrying anything in the pockets.
Finally, the waist belt adjusts with hood-and-loop for a very wide range of adjustability. There's a full-circumference zipper and an 20cm zipper for attachment to pants. In addition to the black/tan as shown in the picture the Tour Master Coaster Air II leather jacket is also available in all black. You can find the Tour Master Air II Leather Motorcycle Jacket here.
