DescriptionThe whole story▼
White turns the Leatt 5.5 Pro Evo into a clean, bright statement over a race jersey, and behind that finish sits the most complete hard-shell layout Leatt builds for chest, back and shoulders. Level 2 certification front and rear, Level 1 shoulder guards and side panels that reach around the ribs make it a protector for riders who want coverage first.
Compared with the model it succeeds, Leatt reports a 30% weight saving and 50% more airflow, which matters most on hot motocross days and long enduro loops. The white version pairs well with light-coloured kit and stays visible when you ride in a group.
Key Features
- CE impact rating: chest Level 2 (EN 1621-3), back Level 2 (EN 1621-2), shoulders Level 1 (EN 1621-1)
- FlexMesh Pro armour under a hard shell, with flex joints for 3D movement
- Hard-shell flank panels with adjustment for rib and side cover
- Longer back plate for extended spine coverage
- BraceOn system, slimmer than before, with removable front and rear plates
- 1.80 kg; Leatt rates it at 19 protection points and lists FFM and ISR
- Packed in plastic-free packaging
Built Around Coverage
The white 5.5 Pro Evo protects more surface than a typical chest protector. Besides the chest pad, which Leatt has enlarged on this generation, the set includes shoulder guards, adjustable flank panels for ribs and sides and an extra back panel that lengthens the spine cover. The plates articulate against each other, so you can still tuck and stand on the pegs freely.
The shell itself is HDPE according to Leatt's technical data, and the full product breaks down into 38% polyethylene, 31% EVA, 28% polyurethane and 3% other materials.
CE Ratings in Detail
Under EN 1621-3 the chest reaches Level 2, and under EN 1621-2 the back reaches Level 2 as well; the shoulder caps are tested to EN 1621-1 with Level 1. The protector is placed on the market as PPE under Regulation (EU) 2016/425.
Leatt adds three of its own references: FFM certification from the French Motorcycle Federation, an ISR rating and a protection score of 19 out of the brand's scale. Treat these as manufacturer information that helps compare Leatt models with each other.
Airflow
FlexMesh Pro replaces large closed surfaces with an open, mesh-like armour. Leatt quotes 50% more ventilation than the previous model, which keeps heat build-up down when the white shell sits in direct sun or when you are working hard in technical sections.
Wearing It With a Neck Brace
The slimmer BraceOn system is shaped for a Leatt neck brace, and Leatt confirms it for over-shirt and under-shirt use. Both the front and the rear plate come off, so you can match the protector to the brace you already own or ride without a brace.
Sizes and Adjustment
The 5.5 Pro Evo comes in S/M, L/XL and XXL for riders between 160 and 196 cm tall. Over-the-shoulder straps set the height of the chest plate, and the flank panels are adjustable for a close fit around the ribs. If you sit between two sizes, the strap range helps you fine-tune the fit.
What you should know
Level 2 applies to chest and back; the shoulder guards stay at Level 1. At 1.80 kg this white protector is heavier than lighter roost guards and soft-shell models, which is the trade-off for the hard-shell side and back coverage. The weight and ventilation percentages are Leatt's comparison with its own previous model, not an independent test.
Colour
The white finish looks sharp with bright race kits and keeps the protector easy to spot. It does show mud, roost and scuffs faster than black, so plan on wiping it down after wet rides if you want it to stay bright. On the plus side, a light surface tends to absorb less heat in strong sunshine.
