I thouht I’d give base layers a go as my textile jacket is a bit brine of late. I bought some Forcefield ones from Infinity Holborn for around 70 quid for the pair. The difference is unbelievable. They work amazingly well and post ride I was super fresh instead of super brine. I would say they help reduce rider fatigue as if you are brine then your going to be un comfortable which can reduce your concentration. In addition they are so comfortable I may need a set for PJs and a few more for work and to wear around the house. Invest in a set today, you can thank me later.
How different are they to a set of £5 thermal longjohns/tshirt?
