Range
Device families and body areas
XO Armor distinguishes thumb and finger devices, hand and wrist devices, foot and ankle devices, and athlete protection. Its range therefore includes orthoses and splints as well as sports guards; it should not be presented as one interchangeable cast product.
The athletic range is described across football, baseball, softball, rugby, and basketball. Those sports categories are separate from the anatomical device categories and do not establish a single shared guard shape.
Construction
Shell shape and open patterns
The illustrated wrist shells have repeated honeycomb openings, larger thumb-area cutouts, and elongated edge slots. Other photographed thumb and athletic guards have more continuous surfaces, so an open lattice is a feature of selected designs rather than the entire family.
The hand and wrist range distinguishes palmar designs without a thumb component from versions with thumb support. It also includes gauntlet-style and flat-print forms with different coverage shapes.
Design options
Material, color, and accessory differences
XO Armor describes several material options and varying levels of material flexibility. It also describes padding and adjustable straps as device options. These are product-design characteristics, not a single material or accessory specification shared by every model.
The manufacturer shows shells in multiple colors, including blue, white, red, and black. The reviewed family pages do not identify a universal polymer formulation or material grade, so no specific resin is assigned to the photographed devices.
Family differences
HeatForm is a distinct flat-sheet range
HeatForm Orthotics are described as pre-shaped, 3D-printed flat sheets with slots for strapping. This construction differs from the curved shells shown elsewhere in the XO Armor range.
Named HeatForm designs include finger splints, palmar and dorsal cockup splints, a gauntlet thumb orthosis, and a radial-based thumb spica. These are separate shapes within the brand family, not evidence that every athletic guard shares the same construction.
