Kask Nirvana: Large aero helmet in beautiful colors
With the Nirvana, Kask offers an aero helmet that appears large on the Velomotion dummy head, but is actually quite compact. At 297 grams in size L, it's also comparatively light considering its largely closed shell and its teardrop shape. Four vents in the front and a wide rear air outlet divided into three sections by reinforcing ribs ensure good ventilation.
The Nirvana's interior features unusual materials: The padding is covered with a layer of merino wool—a material that's kind to the skin and antibacterial. Kask's proprietary "Multipod" anti-rotational protection is an inner shell bonded to the helmet body with a 3D-printed material. An unusual choice of material is synthetic leather for the chin strap. It's not easy to push through the closure and is quite stiff compared to typical fabric materials. However, it doesn't compromise comfort unless you overtighten the chin strap.
The Nirvana has a rather wide fit and runs quite large. While its sister model, the Elemento , is available in size S for head circumferences starting at 50 cm, this helmet only starts at 52 cm. Size M covers 52-58 cm, and size L 59-62 cm, so only a fairly narrow range. Trying this helmet on at the retailer would be particularly worthwhile.
Kask offers the well-made Nirvana helmet in five color options – in addition to black and white, three attractive and unusual designs. Compatible with the Nirvana is the merino wool liner with ear protection , which Kask sells for 50 euros. The helmet itself is relatively expensive at 360 euros, but at least it's "Made in Italy".
