Between two sizes? The Apex Pro softshell is engineered for a compressive zero-interference fit — size down for a second-skin feel, size up if you layer underneath.
// MATERIAL SCIENCE
Non-Newtonian
Impact Core
The D3O® Ghost compound stays soft until it isn’t. Two phases of one material — engineered to disappear at rest and turn rigid at the moment of impact.
// STATE 01
Active State
Molecules glide freely. The armor flexes with every motion of the rider for full range and breathability.
// STATE 02
Impact State
Under shock load the molecules lock instantly, dispersing kinetic energy across the panel before returning to pliable form.
95%
Energy Dispersed
Verified to EN 1621-2:2014 CE Level 2 at the back, chest, and shoulder panels.
< 9ms
Lock-Up Latency
Phase shift from pliable to rigid happens faster than the human pain reflex.
0.4 kg
Panel Weight
Each Ghost armor pod weighs less than half a smartphone — you forget it is there.
