I have taken a quick look on Google and know exactly which gloves you are looking at. All I would say is that you should stay well clear of any site trying to sell “silver gloves” online. These gloves are a con and are not made from silver. Silver is considered a precious metal and so is very expensive and wont be found in a pair of gloves costing £29.99. The fact that they are willing to lie about what the gloves are made from should make you question all of their other claims about the gloves. In my opinion they look like any other cheap cotton gloves with pieces of thin tin foil sewn into them. You would be better off just buying a pair of cotton gloves for £2 rather than these gloves as they will not provide extra level of insulation to your hands.
For Raynaud’s disease the most effective gloves that will help prevent and treat episodes are ones that provide compression. Compression helps boost the circulation in your hands and fingers and keeps blood flowing to them…this means that when you are struck by an episode blood flow is not cut off as much to your extremities lessening the affects of the episode as a result.
I hope this helps 🙂
