I got the Alpinestars
TZ-1 and I like it a lot. It seems to be very high quality and highly protective.
It really keeps the cold and wind out, but its probably hot in warmer weather.
It has some perforations at the shoulders, but I don't feel much of a flow through
them. It has armor in the elbows and shoulders and padding on the back. It has
lots of pockets and an easily removable liner. Got it from kneedraggers.com
for $270. - YZF600Rider
