ACTIVE Best of 2015: Running Apparel

Horizontal stripes have never looked this good. Warm enough to wear on its own in crisp fall weather, this top is also thin enough to layer under a jacket for colder temps. The seamless fabric is so comfortable, you may find yourself wearing it even on rest days.

Saucony has solved multiple running problems with just one pair of tights. The satiny PowerLuxe fabric keeps you warm in brisk temperatures, but prevents that sticky, humid feeling you get after working up a sweat. Ankle zippers allow for a quick change and sleek leg pockets provide lightweight storage for gels, gloves or your ID.

Who wears short shorts? Simple but effective, these classics will be your go-to shorts on race day—or any day, for that matter. Perforated front and back panels enhance ventilation, and extra wide leg splits allow for maximum movement.

Warm but amazingly thin, this New Balance jacket might just be your new favorite for before, during and after your run. The athletic, close fit and Polartec Alpha fill keep you toasty warm, but the lightweight design keeps the bulk at bay. The stretchy sleeves lay flat against your wrists so cool breezes don't find their way in, and thumb holes provide extra hand coverage for colder days.

These unisex gloves that convert to mittens are a must for your blustery winter runs. The windproof mitt cover protects your digits, while the tech-friendly thumb and index fingertips let you still get in your running #selfie.

The tag might say "light cushioning," but these socks feel like you're running in your favorite cushy slippers. The iWick fibers pull moisture away from your skin so your feet stay cool and dry no matter how much you sweat.
