I just gave away a Tourmaster Air 3 jacket and matching pants, as well as an evaporative cooling vest, to a friend's son that just started riding and only had a helmet. They served me well for a couple of years on trips from SoCal to Yellowstone, Oregon, and across country to NC and back.
With the LT's superior weather protection, I never used the rain and thermal layers, but you may need them on a HD or other bike with lessor fairing coverage. Around town, I normally did not wear the pants or cooling vest, only the jacket and jeans. On longer trips, in low humidity heat, the cooling vest under the jacket worked well for about 30-45 minutes, before the water evaporated and then rehydrated with my sweat. I also found that I needed to stop and wash the jacket and pants at least once a week on trips, as they began to smell gamey. The textile jacket/evaporative cooling vest combination did not work well in low humidity, high heat (105+) degree areas and evaporative vests don't really work in more humid areas.
Textile equipment are reasonably priced, but from what I understand, get pretty much trashed if you drop a bike at speed, and may not be salvageable.
I have since graduated to an Aerostich Roadcrafter R3 suit which has proven to be much better than the Tourmaster combination and is comfortable up until temps reach the mid-80s and higher. On longer trips, I use a Veskimo cooling system, which has kept me comfortable riding in 112 degrees. The suit also provides much better protection than the textile combination I had previously worn, even in hard rain or 32 degree weather.
Hope this helps in your decision making.
