When working with heavy welding you need garments certified according to EN ISO 11611 class 2 which is the highest level of protection in combination with EN ISO 11612.The design is very restricted in the EN standard to ensure that welding sparks do not stick to the garment or go inside an open pocket.The UV and heat radiation will challenge the PPE clothing and cause heat stress for the wearer. we have added covered ventilations to increase the users comfort and avoid heat stress on some range suitable for welding. To block radiant heat and increase protection, a Skinsafe system of 2 or 3 layers is recommended.
