COMFORT PRIME

Inner for fabric dry. Adopted “PRIMALOFT” insulation developed for the US military, which requires rigorous training,
and combines warmth, lightness, strong water repellency, and ultra-fast drying.
It incorporates detailed considerations in pursuit of usability, such as a ventilator for both upper arms (easy to exhaust dead air in the inner) and a feet code (to prevent the hem from rolling up).
Even neoprene dry can be worn by adjusting the fitting.
