Bought and rode in it 2-3 times at the kart track and never crashed it. its just a little too snug for me. For reference i'm a 52 in Astars gp tech v2 w/airbag its comfortable, this one is just cut quite a bit slimmer, i'll probably buy a racing absolute once this sells and if this doesn't sell i'll just keep cycling so i'm fairly firm on price. $1100 shipped. size 52 euro 42 us (STG has good sizing information in their videos) Tech air vest compatible (vest not included) knee pucks have a little wear from a couple kart track rides
