I love the Latitude...I went through a few dozen jackets over the years before I finally found one that was "just right".
I've worn it in some monsoon downpours, and other than some moisture wicking in around the collar and at the wrists from my gloves not doing their job, I was nice and dry.
Venting is decent...I've worn it up to @ 80 degrees, and if moving I was fine. Stopped, I started to get uncomfortable. I wouldn't want to wear this as a summer jacket (unless you knew it was going to be a rainy ride...if the sun comes out, you're probably toast). But this was my mild to cold weather jacket (with a heated liner, I was comfortable down into the low 20's). I wouldn't be getting rid of it, but I'm bike-less for the time being and it's just been collecting dust in the gear closet for a while.
Fit is typical Klim "American fit"...I'm @ 215lbs., 48" chest and wear an XL t-shirt and it fits me just right. I'm a 3X in Rev'It stuff.
