Alpinestars Bionic Race Back Protector (size SM Only) 4.6 5 47 47
Snap in system is awful for a one piece suit-go standalone This whole snap in system is terrible. At least with my EU 48 size CR-1 suite, I can't put on the top half of my suit with the snap connected, and it's impossible for me to connect the snap myself after I've put on the top half of my suite. I ended up using a Bionic Race back protector (that I purchased last minute from a local shop after I returned my Revzilla order for being too small# for a track day weekend and sincerely regretted the purchase. I ended up simply wearing it without snapping it in, treating it like a standalone back protector without the support of shoulder straps. If you have a two-piece suit or jacket with the snap connection you might be ok, but I would not recommend this for a one-piece suit. A standalone product will serve you better. Small and Medium size back protectors #and probably all sizes) have the same size back protector. The only difference is the size of the waist belt. October 28, 2015
Good protection, lightweight. Great product the only thing is the fit the waist band is very small. I'm a size 32" waist, 5ft 7" and 69kgs ordered a medium and it's too tight!! Best order large if you want a good fit.. September 29, 2015
Snapped into my Motegi leathers perfectly Snapped into my Motegi leathers perfectly. Leathers are much easier to put on and take off now with the back protector snapped in behind the mesh. August 24, 2015
Fits well under leathers I haven't come off the bike yet since running with this back protector, but when I do (its just a fact of life at the track), I'm sure it will stay put and do its job. It is low profile, so no need to size up leathers to make room for it. It also integrates well with Astars leathers. August 6, 2015
This is a great product love it This item is great it's great on the track it's light fits great August 3, 2015
Good product for price This is a good product for the price, it does make my Dainese suit feel a bit constricted around the chest area with this on but I guess that's just my suit being a bit small perhaps. Under my jacket it fits just fine though. Would recommend June 8, 2015
Gets the job done I'm using this with an older Alpinestars Trigger 1 piece suit. First time out on the track with it and I unfortunately had to put it to good use. First, the fit is good, I don't even notice it's on when I'm riding. The waste straps are really tight. I have a small frame, slightly wider at the belly but nothing I would call a large beer belly. The waste straps are extremely snug, even when fastened at the widest setting. I can't get my suit on with this protector snapped into the suit. It either gets awkward or it comes unsnapped. So, I just put the protector on, then the suit. It's snug enough that even though it's not snapped into the suit, it stays in place just fine. This past weekend, had a small low side coming out of a corner, slid on my side and back for a bit. I came out of it completely unharmed. My suit of course did the most work, but this back protector gave me a good level of reassurance as I slid across the pavement. Recommended, but their newer version may fit better. May 24, 2015
Worth the money Haven't had an issue with mine yet. Fits comfortable, and does not impede my movement in a 1-piece suit. I forget it's there. April 15, 2015
