Neutral:
the drawstring is the class idea is small, tidy, saving space and weight.
But you should already similar a headband Buff-cloth cap wear because the string so tightly stretched that the welts on the head (even if at the hand-tied) otherwise quickly hurts. But that one can treat by aids.
- Negative: nothing really
Conclusion: for a small price a small forehead and travel lamp with a long service life and the red light, which is relatively rare, is not it a lot more expensive and more difficult in the headlamp range. Also for the handbag, the belly bag, the glove compartment. Had she bought me for weight reasons (Grammjägerei) for the Way of St. James and used nightly.
