OK, tried them out on a V. Frosty frozen Sunday morning.
Jeez, are they UUUUUUUUgly, other roadies threw rocks at me instead of the usual grimace.
However, they're comfortable, fit well, help keep the cold out in the areas I hoped for and are simple to use. There is a slight rustling when wearing them, but a bit of strap adjustment helps minimise this.
For £7 I reckon they're a worthwhile addition to my foul weather kit. Whether my pals will cycle with me when I'm wearing them is another matter. Definately will use them on my short, work-dressed commute though.
