Parts & garments

Add to the system you own.

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.

Shipping, plainly. A parts-only order ships small parcel for $12. Add anything to a system order and the whole order is the one $59 UPS Ground charge — which order is cheaper depends on what is in it. Free over $1,200, and one shipping charge per order either way.
Fits the AR-4.0 Pro only

AR-4.0 garments

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.

AR-4.0 Arm Sleeve

AR-4.0 Arm Sleeve

Includes: one arm sleeve.

Single sleeve, hand through upper arm and part of the shoulder. Running one sleeve on its own needs the hose bundle receptacle plug.

$195+ $12 small-parcel shipping, or $59 shipped with a system
Arm sleeve size

Interchangeable between those two

AR-3.0 & AR-2.0 garments

The AR-3.0 and AR-2.0 share a garment fit, so anything here works on either unit. Not on an AR-4.0.

Leg Sleeve Extenders (pair)

Leg Sleeve Extenders (pair)

Includes: one pair of leg cuff extenders.

Adds circumference to an AR-3.0 or AR-2.0 leg sleeve that is snug on a bigger thigh. Cheapest fix for a sizing problem.

Not sure which generation you own?

The model name is printed on the control unit. If it is not, send us a photo and we will tell you — better than a $325 pair of shorts that will not plug in.
