Always worn full finger Inners, haven't tried the fingerless so can't comment. Moved over to Puma this season (Just bought a load of Puma kit and like everything to match, OCD) but had a spare pair of GN left over which I'm using up before using the Puma's. Agreed on the longevity of the GN Inners, only last about 5-6 matches before you feel they need changing. Always buy my Inners post-season so get them for a few quid a pair, so not too bothered. Will let you know about the Puma Inners when I get a chance to wear them.
Does anyone wash their Inners after each use? Might make them last longer?
