Like Lisa, I'm a BIG fan of the Nightlife line. I have the jacket, the vest, the lightweight long-sleeved Podium-style top, the heavier long-sleeved half-zip Vapor Dry (see link below to a GREAT deal on STP), plus the form-fitting Equilibrium long-sleeved and short-sleeved tees. Love 'em all, but especially the jacket and the Vapor Dry top.

I feel much safer on the road when I've got at least a bit of the screaming yellow Nightlife on. Even when it's warm (70s), I'll partly roll up and tie the jacket around my waist, just to give myself extra visibility on the road.

In terms of fit, the Equilibrium tees are fitted, but the other items are pretty relaxed shape-wise. I wear a Small (or XS when I can find 'em); 5'3", 120 lbs.

If you really look around online, you can find terrific half-price-ish deals here and there.
