Chest Protectors & Roost Guards MX

How to choose a chest protector

Coverage level is the first decision. A roost guard deflects flying stones and dirt, while a full chest protector adds certified impact armour across the sternum and spine. CE protector standard EN 1621-3 covers chest impact zones and EN 1621-2 covers back protectors, with Level 1 absorbing up to 18 kN average transmitted force and Level 2 dropping that below 9 kN for the highest tier.

Type	Standard	Best for
Roost guard	Deflection only	Track days, vented summer riding
Chest protector	EN 1621-3 Level 1 / Level 2	MX racing, enduro impacts
Back protector insert	EN 1621-2 Level 1 / Level 2	Spinal coverage, neck brace pairing

Fitment matters more than size labels. Junior protectors suit riders around 25 to 50 kg, while adult units span S to XXL across chest measurements from 86 cm to 122 cm. Adjustable shoulder straps and side cinches let you tune cover over a jersey or a base layer. Look for a 10 mm to 20 mm padded foam layer behind the hard shell for shock spreading.

Neck brace compatibility is essential if you ride a brace. Hybrid designs integrate a brace mount and shed 30 to 40 percent of bulk versus older full harnesses. Ventilation channels keep core temps down on 30 degree days, and a 1.5 mm to 3 mm polymer outer shell stays rigid where it counts. Match your protector to your discipline before you ride.

Frequently asked questions

What is the difference between a roost guard and a chest protector?

A roost guard deflects flying stones and dirt off your chest but offers no certified impact rating. A full chest protector adds hard armour over the sternum and back, with many tested to EN 1621-3 Level 1 or Level 2 for impact absorption. If you race or ride aggressive enduro, choose a certified chest protector. For relaxed trail and track days, a roost guard does the job.

How do I size a chest protector?

Measure your chest circumference at the widest point and check it against the brand size chart. Junior models from Leatt and Thor suit lighter riders, while adult units run S to XXL. Adjustable shoulder and side straps let you fine tune the fit over a jersey or base layer, so the shell sits flat against your sternum without shifting when you move.

Are these chest protectors neck brace compatible?

Several models in this range, including hybrid designs from Leatt, integrate a neck brace mount or are built to sit under a brace. Check the product description for brace compatibility before pairing. A protector designed for brace use sheds bulk and keeps the brace seated correctly during a crash.
