Comfortable, can wear for hours of riding without blisters and plastic smelling arm and it's breathable on a completely different level to anything I've used before. But mainly - it completely fits the bill. Road bike arm, ticks every box from safety to helping me improve my ability on the bike.

Velcro fastening could probably be upgraded for attaching the sleeve to the ALX and tightening to arm.

I have had this prosthetic probably every day for the last year, for up to 8 hours in one day on one ride. It stands the test and passes on another level.
