Portwest B133 Thermal Baselayer Polyester Top

It isn't just your hands and feet that you have to worry about when you have Raynaud's, as a lack of warmth across your whole body is just as likely to cause a flare up of symptoms. Suitable as an underlayer for everyday tops and shirts, the Portwest B133 Thermal Baselayer Polyester Top insulates the body using 100% polyester material, trapping heat and keeping you warm in the worst conditions.

How Does the Portwest B133 Thermal Polyester Top Help with Raynaud's?

Cold temperatures and foul weather are common triggers for Raynaud's symptoms, and you'd think putting on a pair of warm gloves or socks might solve the issue - but keeping your whole body warm is essential for keeping sensory reactions to cold from going into overdrive. Wear the Portwest B133 Thermal Top as an underlayer to ward off Raynaud's and the cold by keeping your body warm and snug.

  • Cyclists
  • Hikers

This product was worn by my husband yesterday on a cold foggy day in the Mendip Hills. He was very happy with the purchase

For Comfort and Warmth
31 March 2021  |  John

This has now become my favourite Winter/Spring baselayer. Its silky smooth finish means that it doesn't "ride up" when worn below other fleece layers. Maybe "Comfort and Joy" would be a better Review Title...
