I've been using the Petzl Cordex Plus glove since 2009, (the dirty pair in the photo), 6 years of mountaineering, rope access and general abuse. I'm convinced these are one of the best general purpose gloves out there and here's why...
Fit: the fit is great, the sizing is very true, I'm typically an XL in gloves but almost always have to put up with shorter fingers. The fingers are in proper proportion to the hand size which is a rarity. The stretch panels across the knuckles let you flex and work with your hands without getting tight backs or achy hands fighting the leather all the time whilst gripping a rope.
Features: one of the best features of this glove is the carabiner hole, this is so useful, I almost permanently keep them on a small snap gate, even when not working in a harness, its just so convenient. The Velcro cuff is what really sets these apart from Chamonix bin men gloves and truck driver style work gloves. The cuff can be secured nice and snug and prevent any dirt, snow or ice from dropping into your gloves, the stretch properties of the neoprene cuff let you get a good fit without worrying about circulation or discomfort.
Overall: excellent gloves, I wear them for almost everything, I've just got a nice new pair provided by Specialist Training Consultants Ltd ready for a Norway trip in Feb where I will use them as a general climbing glove. It's worth getting a lump of G-wax or similar waterproofing for leather boots and working it in if your going anywhere damp or wet. They retail around £40, mine lasted for 6 years, as far as gear goes it's one of the best investments I've ever made!
