The RST Pro Series GP D3O gloves use D3O armor in the knuckle, palm, and thumb areas. Some listings also mention D3O protection on the thumb, fingers, and cuff, with a carbon-fiber knuckle protector paired with the D3O insert.

Placement

  • Knuckles: main impact zone.
  • Palm: added crash protection.
  • Thumb: extra reinforcement.
  • Fingers and cuff: mentioned by some retailers as additional D3O/TPR protection.

What that means

This setup is typical for race-style gloves, where the D3O is used in the spots most likely to strike the ground first. The gloves also pair it with kangaroo leather and Kevlar reinforcement for broader abrasion resistance.

Note

Retail listings are mostly consistent on the main D3O zones, but some vary slightly in how they describe the smaller protections, so the safest answer is: knuckle, palm, and thumb.

TL;DR: D3O armor is mainly in the knuckles, palm, and thumb of the RST Pro Series GP gloves.
