I'll add my experience.
I've had the R1 Hoody (Size L) for a few months and I wear it all the time. Mine is black, and I think it looks fine for around town. I wear it pretty much everywhere but work. As for on the trail, I haven't had enough experience weather-wise to give a full report, but it's a warm piece that breathes well and does a good job wicking moisture. I've found that it's too hot for high output hiking in the 30-50 range, but is awesome for light hiking in that range. I'm expecting that it will work great over a base layer for winter hiking. The design is perfect, from the thumb loops and hood, to the long zipper for venting, and the lighter weight fabric at the cuffs and hem for easy layering.
I've had two of the Terramer Geo Fleece Hoodies since last winter and they have their positives and negtives.
First, the positives:
1) Very warm for their weight
2) Form-fitting - great over a base layer
3) Kangaroo pouch - great hand warmer and stash pocket
4) Wicks moisture / fast drying
5) CHEAP! I bought two...
1) No thumb loops
2) Loose fitting hood with poor adjustment
3) "Catchy" fabric that pills somewhat easily (but is also very durable)
I bought a Terramar hoody from STP for $20 last winter and used it quite a bit. I liked it enough to buy another. It's no R1 as far as features, but it gets the job done. I think that the R1 might wick moisture a bit better, but I think that the Terramar hoody would be a great substitute if it had thumb loops and a better hood. However, it doesn't, so since I bought the R1 I've relegated the Terramar hoody to around the house use and campfire/yardwork use, which it is AWESOME for. I bought two (Medium & Large), and the medium is great for warmer temps over a base layer and the large is great for colder temps over a base and mid-layer. The large Terramar hoody over the R1 is an extremely warm and rugged combo.
FYI - I'm 5'9" and about 170 lbs.
