Hey,
Yeah, still got the gloves and still use them, not had any problems and still just as easy to pop on and off.
The ND gloves come with a separate liner glove, but it seemed unnecessarily thick and bulky to me so i've stuck with my old ones - which are just normal thin-ish gloves from an outdoor shop, nothing special. You could wear the thicker ones if you wanted, but I never have a problem with my hands getting cold even with these thin ones, so no reason to swap.
You can change the glove part very easily - it's actually much easier than it was with my old ring system which needed a lot of stretching and I seem to remember needing 5 hands to do it with! With these I can swap them myself with minimal effort, so bonus points there. They take the standard showa type blue (or any other colour) gloves, so if you get a hole in them it's £3.50 for a new pair of gloves (from baconsdozen.co(m/.uk)) - bargain!
I knew my size from the last ones I had. If you go to the baconsdozen site it's got a very rough guide to working out what size you are, but worst-case if you get the wrong size you can just replace the gloves. As far as i'm aware all the rings are the same size.
Hope that helps
David
