Don't get distracted by the word "Extreme" here. It doesn't mean what you think. The first time we saw it we figured by "Extreme" Craft meant this base layer was meant for extreme weather conditions, i.e. frigid temps, blizzards, the ice age, etc. In fact that's exactly what it's NOT meant for. Rather, Craft designed this piece for extreme intensity riding in cool (not cold) weather.
Pro Zero Extreme was first designed for the Swedish Nat'l Nordic Skiing team. In the early and late season, they often skied in cool conditions where they were generating enormous body heat through intense efforts. They needed a base layer that would trap in warmth when they were skiing at a moderate pace, but that could wick and vent like mad when their effort level was pegged. Hence, Pro Zero Extreme was born. Craft recommends its use for high-intensity rides from 25-55 degrees. It's perfect for early season intervals as well as cyclocross racing. It's with Pro Zero Extreme in mind that Craft chose to be the official apparel sponsor of the USGP of Cyclocross.
Pro Zero Extreme is built with hexachannel Pro Cool fabric against your skin, identical to what you get in a summerweight Pro Cool base layer. This hexachannel layer is paired with Craft's hollow-channeled Thermolite fabric to help trap in body heat on cool days. It has a seamless torso, so a tight-fitting long-sleeve jersey won't cause your base layer to chew into your skin. Adding to the comfort is the fact that Craft has gone to what they call 3D cutting lines. You won't see any straight seams on the Pro Zero Extreme. The panels and seams are curved identically to the shape of a cyclist reaching for the handlebars. Available in Black in sizes Small through XX-Large.

This might be the best winter baselayer ever. It relies purely on insulation and not on windblock, but when you combine it with a nice jacket (such as the Craft Storm jacket) it gives you plenty of warmth. The crew neck is just right -- it stops right below the adam's apple. Also, if you're stuck between sizes, choose the smaller size. I can use M or L in base layers, and I'm happy as a clam with M. This sucker is thin, light, and super-warm. You'll love it.
Comfortable, super nice material and it does exactly what it's supposed to do; keeps you warm and dry but allows you to easily shed heat if too much builds inside your shell. I wear this under a GORE Contest AS and it's a really nice combo.
It is a too warm above like 45 degrees for me.
For me I actually went with the larger size between the 2 that might have fit.
The best baselayer for high output aerobic activities. Period.
Breathes extremely well so it's comfortable in a range of temperatures. If I'm working hard and it's below 40*, this baselayer is on my back. I've owned the SS and LS version for 4 years and they are holding up very well. Highly recommended.
Who needs warmth from a loved one on those long cold rides when you have this Craft base layer? I was riding in sub 30 degree temps and it kept me feeling just ride. Wicks away moisture very well so I didn't freeze on the descents also.
