Good question. Well first before that happens, you'll get warnings at approximately T-3 hours, 1 hour left, 30 mins left, 10 mins left.
From there you just need to find a wall outlet and use the included charger. Typical use will have you good to go for an 8 hours of continuous high energy use (up to 12 on lower intensity activities).
Very breathable I assure you :) From nose to nearest front part of helmet is already at least a few centimeters. Think of a somewhat more spacious face shield in the regard.
Hey guys, we're super excited to launch our augmented reality helmet product, this first flagship version focused heavily around the developer and researcher opportunities.
