Anyway, so shortly after becoming a member of the "Tribe", I was sent two of the Men's Helix Mountain Tee Body-Sensors t-shirt, a long sleeve and a short sleeve. Having recently converted to being a trail runner, as opposed to a road runner (insert looney tune pic here), I can honestly say that both of these shirts have become my go-to shirts for training and racing alike. Not only are they functional, they are also rather stylish as I've had absolutely no problem wearing them out to town. They also serve their original function of being a base layer quite well.
If I've had any complaints about the Helix Mountain Body Sensor shirts, it be only one and it is this, both of them are black in color and being such, on a warm day's run with the sun beating down upon you, black is not the best color to be running in nor hiking in or much of anything else for that matter. Other than that, the shirts perform great at wicking away moisture and keeping you warm. Although I do have to say, when it's lower than say 70 degrees, especially if there is a breeze, the shirts by themselves are a bit too breathable, but that does come in handy when you're core temp is up from being so active.

So if you need a lightweight base layer that performs in any given range of climates ranging from 30's to 80's and higher, I would highly suggest the Helix Mountain Tee Body-Sensor line from Terramar Sports. They have not failed, or let me down yet, and I've had them on many a trail run and a couple of hikes too. For the gearheads out there, here's some of the technical specs on the jerseys:
