Shielding headgear

Description

Properties

The modern alternative to a headscarf! This headgear (a fabric sleeve) can be worn in several ways: as a cap or as protection of nose, mouth and neck. For complete protection of the head use 2 headscarves – 1 over the head and one over the nose, mouth and neck. YShield’s Silver-Elastic fabric is very flexible and perfect at adapting to the shape of the head. Due to the high content of silver, Silver-Elastic is very durable and has an excellent attenuation of 50 dB at 1 GHz.

Please be aware that due to hygiene reasons, this product cannot be returned or exchanged.

How to put on the headgear

A headgear is usually worn as “pirate bandana”: 1) Turn inside out so that the seam is visible.  2) Put the headgear on your head (middle image).  3) Hold the underside of the headgear. Now take the upper side and pull it back over your head with your other hand. Finally, cover your head.
