Having quality running gear for cold-weather runs makes it just a little bit easier to head outside when it would be easy to stay inside. The Asics Thermopolis Long Sleeve Shirt is one of those pieces that make you happy just putting them on. Unlike a lot of technical tops, it has a bit of heft to it, giving you some insulation at the base-layer level. You may be surprised how often you can get away with running without a jacket before the temperature drops.

It’s got a slim fit that’s nice for when you do need a top layer, and the comfortable next-to-skin feel is welcome whenever you put it on. The kangaroo-style pocket in front is handy when you’re waiting to start the run, and the thumb holes in the sleeves offer you a little more coverage on those chilly days. Reflective material on the cuffs and back gives you added visibility on those dark streets. In short, it’s a top that will provide you with that added bit of warmth at the start of a run while still managing sweat effectively once you get moving.
