Fits good so don't worry about it shifting. Does ride high on back of neck some

my chest size is 42 i first ordered L it was good but tight i hear it ripping when i wear it then i ordered XL , very comfortable but elbow protection doesn't stay in place otherwise it's good, by the way it's not breathable except to sweat alot , back and shoulders protection is excellent, chest should be a bit larger it's a nipple protector actually. but i would buy again.

I bought this for snowboarding because the pictures showed what appeared to be D30 material (the orange pad) in the shoulder area. D30 foam is relatively soft and flexible, made of free flowing molecules. On impact, the molecules instantly lock together and become hard, providing excellent impact protection. After I received this jacket, I removed the shoulder protection pieces to see if it was really D30. There is no embossed D30 stamp on the orange pieces that I've seen on genuine D30, so I don't know if it's real or a knockoff material.

The back protection is excellent, with half inch thick high density hard foam. The segmented arrangement of the foam pieces allows it to flex freely. There is a very thin 1/8 inch soft foam piece sewn into the inside that goes against your back. One negative feature of the back protection is that it is extremely long. If you wear the matching BenKen butt pads or any other butt pads, the back protection will overlap the butt pads. The back section on my jacket is 27 inches long. The shoulder and elbow protection are good, although as I stated, the orange pieces may not be genuine D30. Also, the elbow pads sometimes rotate around your arm to the side of your elbow. Requires frequent adjustment.

The weakest part of this jacket is in the rib and chest. Those pieces are quarter inch soft foam which provide minimal protection. Also, the jacket zipper is a small female style left handed zipper with the parts on the opposite side of regular men's clothing.

I have a 33 in waist, athletic build, and about 5'10" tall. Based on my past experience with Asian sizing, I got the XL and it fits perfectly. Normally I'm between a medium and large in US sized clothing.

I have been using the Troy Lee Designs 7855 Upper Body Protection for the last four or five years with great results. Never once had a crash that I couldn't just walk away from like nothing happened. It costs three times what the BenKen jacket costs, but the protection is excellent all the way around with every part of your upper body covered. Its weakness is in the shoulder, which is why I bought the BenKen. More than likely, I'll stick with the Troy Lee though. I need the full upper body protection for snowboarding park features.

I would recommend this if you are mainly interested in back, shoulder, and elbow protection. The chest/rib protection is poor, and the jacket is an awkward fit with butt pads.

All it took was one crash on my mountain bike to realize that I need GOOD protection. I did research and bought this product. It zips up like a tight jacket. I throw a shirt on over it and I'm good to go. I dont even know I have it on. It used to be a pain to put on all the protection prior to a ride, but this eliminates all that. This is easy, it wears well, and very low maintenance. 5 stars all the way around. I'd buy it again in a heartbeat.

I'm not a fan of hard-plastic protection. If I went over 30mph on my electric board... then I would reconsider.

I really like this because it's comfortable enough to wear under a long-sleeved shirt or a hoodie. I also wear a t-shirt under it for comfort.

My only complaint is that the elbows tend to slide around, but that's probably a sizing issue. (I usually wear a medium but ordered a large because I'm very tall and have long arms, but I'm still glad I got a large).
