POC Receptor BUG Adjustable Helmet

What POC says about the Adjustable BUG:

To make our most appreciated helmet; Receptor BUG , suitable to even more users, we have added a size adjustment system. The proven safe construction of the Receptor model with the patented overlapping double shell system offers a well ventilated helmet without sacrificing penetration resistance. An advanced outer shell and the in-mold liner in polycarbonate and EPS offers a tough and durable construction and provides excellent protection.

• The overlapping double shell technology features an aramid ballistic penetration barrier, so you don't get jabbed by branches
• Eight vents draw in cool air between shell layers and expel hot air out, keeping the comfortable flow going while shredding; they also close for cold days
• The size adjustment ensures a safe and snug fit with the help of a soft, adjustable chin strap
• A liner aids breathability and wicks the excess moisture of a boot pack or hot lap down the front side
• A hard outer shell, a polycarbonate and EPS inner shell, and an in-mold SEPP foam liner provide strong, lightweight protection in case you tumble through the trees
• The SEPP liner withstands multiple impacts, so you don't compromise its effectiveness after just one fall
• Compatible with almost all goggles types
