I bought these TNF gloves a couple of days ago in the CO online sale, and first impressions are they very comfortable, extremely well made and, more importantly, keep you fingers and hands very warm. I particularly like the silicone palm which helps improve grip (useful for winter driving) and gives the gloves a solid but comfortable feel.
Just to point out that although the gloves are lightweight, I doubt they could be worn whilst using a keypad or touchscreen - if this is what you want to do, you'd be better off buying the ETAP gloves (albeit you'll be sacrificing some warmth factor if the reviews are anything to go by).
The gloves are indeed a snug fit as stated in the product spec (but not overly tight fitting) and I ended up exchanging the size L gloves purchased online for an XL pair in a CO store. Personal choice this and a trade-up in size probably wouldn't be for everyone, but it may be worth trying them on first before buying just to make sure.
A small query to CO - my wife liked the look of my TNF gloves so much that she decided she wanted a pair of her own, however the women's version (which seem identical to mine) weren't in the sale! Seems a little unfair don't you think? Problem solved - she bought a pair of the men's glove in a size S.
