Materials
ABS plastic and open shell construction
ActivArmor identifies its shell material as 100% ABS, short for acrylonitrile butadiene styrene. Its material page describes this as a hard, durable plastic. This material description concerns the rigid shell; the manufacturer separately identifies nylon and bungee components in its closure designs.
The official product photographs show an open pattern of differently sized cutouts separated by solid plastic ribs. The illustrated shells also have distinct edges and seams. These visible construction details distinguish the family’s perforated shell design from a continuous wrap.
Family design
Body-area shapes and coverage
The manufacturer lists the wrist, elbow, hand, fingers, and ankle among the body areas represented by ActivArmor designs. It describes individually contoured geometry rather than one universal shell. Its design discussion also identifies shell thickness and coverage area as design considerations.
The gallery focuses on wrist and forearm examples. These illustrate differences in outline, cutout placement, and color, but do not establish a complete model list or show the elbow, finger, and ankle designs.
Configurations
Locked-on casts and removable splints
ActivArmor documents both locked-on cast and removable splint configurations. Its FAQs identify locking nylon ties positioned at the seams for the locked-on version. Its family design description also identifies a bungee closure option for removable configurations.
These are closure differences within a custom-designed family, not standardized size variants. Photographs may show different seam and closure details, so the green, black, orange, and blue examples should not be treated as identical devices.
Design context
Water exposure and athletic settings
The published ABS material description calls the shell washable. Official family pages discuss water exposure, including swimming, and the gallery includes a device pictured in a pool. This is a description of the documented material and imagery, not a water-performance guarantee for every component or configuration.
ActivArmor’s athlete page discusses its casts and splints in sports settings. The athletic photograph therefore illustrates the same family in that context. The reviewed official pages do not establish a separate named sports-only protective-gear range.
