The Joint VPD System Elbow is a MTB Elbow pads from the brand POC. Heat, put on, adjust, and it's done, it becomes one with your elbow. Very flexible in use, it hardens upon impact to effectively absorb shocks. Ventilated thanks to its design, you won't overheat, and the polyamide threads composing it are highly resistant to abrasion (this is not a reason to rub your elbow on every turn either).
