The Blaklader FR Undershirt 78% Merino Inherent is engineered for professionals who work in high-risk environments and refuse to compromise on quality. Built from a premium blend of 78% merino wool, 20% modacrylic, and 2% other fibres, this flame retardant thermal undershirt combines the natural heat-retention properties of merino with advanced safety features. The fabric is inherently flame retardant and antistatic, meaning the protective qualities are built into the fibres themselves rather than applied to the surface. Whether you're working indoors or outdoors, this thermal undershirt maintains its warmth even in wet conditions, whilst offering robust protection against electrical hazards and arc flash incidents. The extended back hem provides additional coverage, contrast-coloured seams add durability, and the cuff binding at the sleeve ends ensures a secure fit. Certification labels are visible on the exterior for easy verification of safety standards.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInherent flame retardant protection built into the fibre structure\u003c\/li\u003e\n\u003cli\u003eMerino wool retains warmth in both wet and dry conditions\u003c\/li\u003e\n\u003cli\u003eAntistatic properties protect against electrical discharge hazards\u003c\/li\u003e\n\u003cli\u003eExtended back hem for additional coverage during movement\u003c\/li\u003e\n\u003cli\u003eArc rating of 7.3 cal\/cm² provides substantial electrical protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eRecommendations from our Unishore Expert\u003c\/h3\u003e\n\u003cp\u003eThis thermal undershirt is specifically designed for workers in electrical, welding, and high-heat environments. The merino wool composition delivers exceptional temperature regulation, keeping you comfortable whether you're facing extreme heat or moving between different work zones. Unlike standard thermal shirts, this undershirt offers genuine protection against electrical arc flash and flame exposure, meeting strict safety standards required in hazardous industries. The natural properties of merino mean you stay protected without that stiff, uncomfortable feeling common with synthetic flame retardant fabrics. The contrast-coloured seams and extended back ensure the shirt stays in place during physical work, whilst the cuff binding keeps everything secure. For professionals who understand that safety shouldn't sacrifice comfort, this is a serious investment in protection.\u003c\/p\u003e\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e - 78% Merino wool, 20% modacrylic, 2% other fibres, Merino interlock, flame retardant, antistatic, 225 g\/m²\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCollar\u003c\/strong\u003e - Crew neck with contrast-coloured binding\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSleeves\u003c\/strong\u003e - Long sleeves with cuff binding at wrist\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSeams\u003c\/strong\u003e - Contrast-coloured throughout for visibility and durability\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBack\u003c\/strong\u003e - Extended rear hem for additional coverage\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eArticle Number\u003c\/strong\u003e - 4794-1075\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eStandards and Safety\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComplies with EN 1149-5 antistatic protection standards\u003c\/li\u003e\n\u003cli\u003eMeets EN ISO 11612 requirements for protection against heat and flame\u003c\/li\u003e\n\u003cli\u003eProvides electrical arc protection under IEC 61482-2 Class 1\u003c\/li\u003e\n\u003cli\u003eAchieves an arc rating of 7.3 cal\/cm² for substantial arc flash defence\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Blaklader","offers":[{"title":"Black \/ S","offer_id":49338092814676,"sku":"4794107-S-ZW","price":81.9,"currency_code":"EUR","in_stock":true},{"title":"Black \/ M","offer_id":49336680350036,"sku":"4794107-M-ZW","price":81.9,"currency_code":"EUR","in_stock":true},{"title":"Black \/ L","offer_id":49291924963668,"sku":"4794107-L-ZW","price":81.9,"currency_code":"EUR","in_stock":true},{"title":"Black \/ XL","offer_id":49293477052756,"sku":"4794107-XL-ZW","price":81.9,"currency_code":"EUR","in_stock":true},{"title":"Black \/ XXL","offer_id":49293235224916,"sku":"4794107-XXL-ZW","price":81.9,"currency_code":"EUR","in_stock":true},{"title":"Black \/ 3XL","offer_id":49295362392404,"sku":"4794107-3XL-ZW","price":81.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0875\/7578\/9887\/files\/0081012.png?v=1738664852","url":"https:\/\/www.unishoreworkwear.com\/en\/products\/blaklader-fr-onderhemd-78-merino-inherent-4794-1075","provider":"Unishore Workwear","version":"1.0","type":"link"}
