GripGrab's Windster Cap is a good option for winter riding. Keeping your head and ears warm can be a challenge when cycling at this time of year and the Windster has a windproof front panel with good insulation around the head that should give you a head start (sorry) when it comes to staying warm.
I've been really impressed with GripGrab's gloves and overshoes, and the trend for high quality and well designed products continues with the Windster Cap. Rather than a one size fits all approach, it's offered in four sizes (though wiggle only list three size) covering head sizes from 51 to 62 cm circumference. Fit then was excellent and it wrapped around the head and over the ears with no tightness or restriction. There is also a ladies' version.
Pull a helmet over the top and you barely notice it, it simply disappears. You just notice how well it keeps the cold wind off your head. The soft microfleece material is stretchy and just fits perfectly, and the sides come low enough to cover up the ears. I would like to see the windproof panel at the front extended higher, so there's better protection from the air passing through the helmet's air vents.
We've tested many skull caps on roadcc and the GripGrab sits at the top-end in terms of performance. It also sits somewhere in the middle of the range of prices you can expect to pay, from the expensive Castelli WS Skully at £28 and the Ride Aquazero at £8.99. And because GripGrab is exclusively distributed by Wiggle in the UK, they're already discounting from the RRP - they're currently offering 10% off.
Comfortable, well fitted, and above all top performing skull cap when it comes to keeping your head warm.
