I am using the First Gear Kilimanjaro jacket for its first season. It's been great in the cooler weather. Now that it is finally starting to warm up here in Minnesota, I am finding it hard to believe this is a three season jacket, unless they meant fall, winter, and spring. It has been in the upper 70's or barely in the 80's and it seems really hot to me. I took out the liner and opened the vents. When I'm moving it's not too bad, but when I stop I start boiling. (Inside my full face helmet too.) it probably doesn't help that I have it in black. I can't imagine wearing it when it gets above 85. What have others experienced with this jacket? Am I missing something? Right now I'm thinking I'm going to have to buy another jacket or forego the armor and just wear a t-shirt.
