The Good: Comfortable Not overly restrictive Leatt brace compatible Not too hot Good protection
The Bad: The sizing - I'm 75kg with broad shoulders and tried on the smallest size they had (which is meant for riders between 55 -65kg) and it fit me perfectly. Leatt really need to get a better sizing chart as rider weight isn't good enough especially seeing how completely out their recommended size was. They need to include more specific body sizes such as shoulder width, torso length and arm length (as iXS do). The back protection is of a lower standard than their full body armour (level 1 instead of level 2). Chest plate is too flat and doesn't wrap around the ribs as well as it could.
Surprisingly comfortable, not too hot and fits perfectly with a Leatt. My only gripe is that the back protection is not the same level as the full body vest. Which is something I wanted in particular as I broke my back in 4 places not too long ago. However I figured I'd rather have less than optimum protection knowing I would wear it all year round rather than having the full body vest I could only wear in winter (South African summers are insanely hot). Great product all round.
