Protection+ Extreme
PROTECTION+ by A. SAMPAIO
Extreme ― The ultimate protection for the ultimate demands. Combining Lenzing FR® with metaaramidic fibres offers excellent flame and heat protection and heat resistance up to 260ºc. Lenzing FR® is a fibre produced from wood, which is a natural material. The use of Lenzing FR® fabrics protects against heat stress and heat stroke, always keeping the body dry and cool. Our fabrics have been engineered from fibre to fabric to ensure the best performance and best durability wash after wash. We offer fabric solutions for a wide range of end uses: underwear, balaclava, polo-shirt, polar sweatshirt, softshell and linings. Blends Lenzing FR® / Wool are also available. All our fabrics are fully certified - please ask for more details.

Protection+ Comfort
PROTECTION+ by A. SAMPAIO
Comfort ― When it comes to heat and flame protection, we don't play around with untrustworthy materials. Protal® is an inherently flame-retardant fibre (formerly known in Europe as Protex®) with proven quality and performance. The flame retardant performance does not wear off nor lose effectiveness regardless of the type of wash or number of washing cycles. Protal® fabrics are soft, comfortable and have a natural appearance. Fabrics with this technology are compliant with several flame retardant standards. We also have solutions with antistatic protection and high visibility compliant fabrics.
Standards ― ISO 20471:2013 / ISO 14116:2015 / ISO 11612:2015 / EN 1149-3:2004 / EN 1149-5:2018 / IEC 61482-1-1 / IEC 61482-1-2:2014 (Class 1) / ISO 15797

Protection+ High Visibility
PROTECTION+ by A. SAMPAIO
High Visibility ― High visibility means higher protection and less risk. We have a full range of certified fabrics for different end uses: heat and flame protection, workwear garments, insulation garments (polar fleeces), softshell fabrics and others with high-performance fibres. When combined with flame retardant features, high visibility fabrics can also be found at other ranges: Protection+ Extreme, Portection+ Thermoregulation, and Protection+ Comfort.

Protection+ Thermoregulation
PROTECTION+ by A. SAMPAIO
Thermoregulation ― The challenge was to provide extra comfort to the most demanding users of FR garments. The answer was to develop a revolutionary material that actively regulates heat transfer from and to the skin while providing inherent heat and flame protection. Protal® + Outlast® technology is the result of development cooperation between leading companies in their fields of activity. All the active ingredients are embedded inside the fibres, so performance remains unchanged wash after wash. Fabrics with this technology are compliant with several flame retardant standards. We also have solutions with antistatic protection and high visibility compliant fabrics. A. Sampaio is the exclusive producer of fabrics with this technology. Don't hesitate to get in touch with us if you would like to know more.
