Received the jacket within a couple of days after ordering it on closeout. I am 5'-9", 150 lbs. and the medium fit very well. The spine protection runs high up the back, as you can see in the photo, and the collar is high (not open V-shaped), but even so is not un-comfy. I really like the elbow and forearm protection. My only challenge is that the shoulder shield sits a little low on the shoulder blade. I don't have the most broad shoulders, so that could be the reason, but the fit even with my build is very close to the photo's. I haven't found a way to adjust it higher yet, but I am open to any suggestions.
The suit has a weight to it, but is very comfortable and breathable. My first time with it on, I did a 16 mile loop (in 70 degree weather) of what most riders consider a robust trail (I live in Colorado) with uphill, downhill, XC, singletrack and cross-country all in the same ride. I actually put it to the test on one of the downhills, as I crashed on a curve going about 25 mph into a rock. My right shoulder took the brunt of the impact, but I escaped with only small abrasions on my shoulder blade (and a very sore rotator cuff). I believe the abrasions were from the top edge of the shoulder shield, so had it sat higher or preferably, extended over the top of the shoulder toward the collar bone more, I don't believe the abrasion would have happened. There is no question however, that the armor was a tremendous benefit, and ultimately kept me from some serious pain. I am giving it 4 stars for fit and function, reserving the 5th star for lack of top shoulder protection and the tight collar. Even so, I would highly recommend this item!
