Edelrid Madillo. This is, what climbers and alpinists have been dreaming for in a long time. The Madillo is strong and compact, and due to its small pack size it can be stowed easily in the backpack. The shell sides slide into the top and the back folds in, reducing the helmets pack volume by 50%.Other unique features are the shell made of a high-strength abrasion and impact-resistant injected material. Three different foam materials - EPS, EPP and EVA - provide an optimum of comfort and safety. EPS foam is used in the upper half of the shell as it provides the best shock absorption, while the sides are made of EVA which is softer, providing a better and more comfortable fit. The rear panel of the Madillo covers the back of the neck providing additional protection. The size is adjustable from 52 to 62 cm, made so by squeezing the rear panel forwards once the helmet is on your head. A revolutionary helmet to suit everybody-s needs. In a nutshell: The Madillo is a compact, lightweight and comfortable helmet saving a lot of space in the backpack and making you lookgood at all times.
