I give these gloves five stars because, for the uses I envision, they function perfectly.

Let's begin with the construction. The top is a very stretchy softshell-like material. I don't think it's laminated, but even if I try full-on blowing air through it, I fail.
The palms and fingers are constructed of leather. It's not the classiest leather ever, but it does look very burly. In between the fingers are strips of gusseted leather that allow a large range of motion for each finger. Inside, The small gauntlet is not insulated (only the softshell material) so it is very thin and tight against your skin. It adds a nice look and lets you shove the gauntlet inside a tight-fitting softshell jacket sleeve for complete isolation. The insulation looks like some sort of light-loft fleece. I believe it is a hybrid fleece so the lofted fibers are inside and the smooth low-loft fibers touch your skin.

As for warmth, they keep me reasonably warm. These are not expedition gloves. They are meant to be light gloves and will keep you warm down to 15F or so. Below that you can squeeze some smartwool liners and retain most of the dexterity, or move on to something more substantial. The cold wind doesn't penetrate them at all, although the palm area is thinner to allow for complete mobility and thus tends to get colder than the rest of the glove. These are not waterproof. I used them ice climbing, but only because it was cold enough that there was barely any water involved. They will shed rain, but melting waterfall ice will eventually make it through the glove. Try the Venta SV for something thicker, albeit waterproof. The huge benefit with these is they're dextrous enough to set ice screws and place just about any pro you can think of. Like the name implies, you can set a cam with these things on.

Just a quick note about the design. They are meant to be used for ice climbing or perhaps belaying. This means they are made with the hand cinched rather than fingers straight. If you "open" your hands, you will get a lump of material around the knuckles. It feels a bit weird, but eventually you get used to it.

If you want gloves that you could realistically perform surgery with (but please don't) yet keep your hands warm, these will do the job.

I purchased this jacket with the intention of getting a softshell that's more waterproof than your typical Polartech Powershield/Schoeller based garments but more breathable than a gore-tex shell. So I will be comparing the general warmth/feature-set/breathability/waterproofness to an Arc'Teryx Gamma AR. Now, while generally my experiences with Mountain Hardware gear has been generally described as "meh," the G50 has some great features that for once put it on the same league as the Arc'Teryx softshells.

Fit: It sizes small, although not as small as the skintight shells like the Arc'Teryx Gamma MX's. I generally wear a medium in Marmot, Arc'Teryx, and Helly Hansen and for this jacket I needed a large to get a nice tight (but not constricting) perfectly sized fit. I'm 5'7 150lbs, for the record. When I'm wearing this with a harness, the length is ideal since it doesn't interfere with its placement (or get tangled with my cams).

Warmth: On its own, it appears to be a laminated material so it's pretty thin backed with a minimal fleece. I'd probably wear it alone comfortably from 40 to 60 but definitely not lower. However, this shell doesn't really stand out for standalone wear...
I layered with a Patagonia Capilene Expedition weight crew for the baselayer, then the Arc'Teryx Atom LT for an insanely warm synthetic midlayer, and tossed the G50 on top as a nice shell. I tried out the combo at night during a chicago winter at 10F with 20'ish MPH winds next to the lake. Standing still I couldn't feel a thing.

Breathability: Running, the combination of layers breathed quite well, although with intense work I did need to open the hand pockets a bit for ventilation. Generally it kept me dry.

Waterproofness: During a rainstorm at around 32F I went for a run with a synthetic Helly Hansen baselayer and the G50 as an outer. It shed water for around an hour, but the seams definitely did begin leaking a bit after that. The synchro jacket has taped seams, but of course that sacrifices some breathability. I personally can live with a bit of leaking, but downright amazing performance for a softshell. If you want pure waterproofness, (aka an unexpected rainstorm during a climb) then you'll probably want a really lightweight gore-tex rain shell to throw on top.

Value:
Unlike Arc'Teryx gear, you don't have to pay an arm and a leg for this. For $170 (I actually got this for $120) you're getting a really solid piece of gear.
