Every Air Relax garment and part we carry, at the manufacturer's own price — availability confirmed with Air Relax before anything ships. Two rules worth reading before you add one: check your generation — 4.0 garments and 3.0/2.0 garments are not interchangeable — and size to your inseam, measured crotch to floor in bare feet, not your trouser size.
The 4.0 is a different fit system to every earlier model. These do not fit an AR-3.0 or AR-2.0 control unit, and that mis-order is the most common one in the range.
Includes: the compression shorts.
Six chambers across quads, hamstrings, glutes, hip flexors and lower back. Used lying flat, never standing.
