Is it a neck tube? Is it a beanie? we're not sure either but it's a simple solution that makes for a versatile technical winter run accessory.
We leaned (again) on that future fabric we keep talking about. our COOLmatic | EXP™ DIAMAfleece with carbon seemed about right. integrated adjustable top keeps the neck tube up and turns that very same neck tube into a very capable beanie.
