As a "non-active newbie" to Yoga. It is good to know why it hurts so much on some part on the body that was not caused by some other reasons, like sickness of some sort.

In 336 steps not for a long walk from parked cars to the main door, I was covered with this face shield and the other person was not. Windchill was -25, with blowing snow,we were doing some chit-chat at first, when reaching the front door, I was still talking fine and the other person was quiet for last 30 seconds and was trying to catch one's breath.

Well balance, full tang strength, size small but still palm fitted, reliable sheath locking design, good for camping and/or fitting out emergency pack.
