Based on Zimmerframes great review, I 've just ordered the 7855.I've got a 38" chest and was undecided between a M and a L.It should turn up tomorrow so I'll add my feedback if it helps.The Leatt 5's arrived yesterday and just what I wanted after my recent lucky escape avoiding a broken hip.@Zimmerframe , I'm looking to purchase a TLD 7850 vest. Size wise the TLD chart has me squarely in a Med (37" chest) but I don't want this vest to be floppy at all. I would prefer a tight fit. What size do you wear and what is your chest measurement? I plan on wearing an under armor compression base layer which is like a 2nd skin. I've been back and forth between the 7855 and 7850 and finally decided I would prefer to separate the elbow pads from the vest.. I feel I can dial in the fit up much better that way. I'm looking at the Leatt 3DF 6.0 elbow pads or TLD EG5550, do you have any experience with either of these? Finally, whats you take on Leatt's impact shorts 3.0 vs 5.0? I don't want a chamois in mine so the 4.0 are out.
