Spring can fool you. Longer days and rising temps that lure you into taking spontaneous, hour-long breaks from the office can also lull you into believing that all is warm with the world. Until, that is, you hit the pavement for an A.M. run, or rush out to catch an early morning flight wearing nothing more than a T-shirt and discover that those pleasant 60 degree temperatures have dropped back down into the mid-40s.

To help handle the shifting mercury while traveling, hiking, or cruising the city streets, we highlight two companies—one an outdoors staple, another whose name is more familiar to the shoe-obsessed—and four pieces of apparel (two for each gender—though both labels make clothes for men and women) that are perfect for this celebrated season.

FOR HER:
1. Columbia's Summit Sister Jacket
One word for a solid spring apparel strategy: layering. And this featherweight jacket offers the ideal protective layer for a morning hike or a spring run. Made of nylon ripstop fabric and equipped with a roomy hood, it repels wind and drizzle during inclement conditions, with a stretchable back panel that provides both flex and breathability. Femme-specific details like a lengthier cut at the back, articulated elbows, and a fitted waist allow for unrestricted movement without feeling like you're wearing a trash bag. Better still, the fashion-forward silhouette and stylish color selections let you travel from trail to coffee shop without looking like you're training for Olympic gold. ($95)

2. Columbia's Signal Mountain Shell
Of course, sometimes the weather can turn downright foul. So when Mother Nature opens the gates, retreat to the shelter of the Signal Mountain Shell. This classic jacket (with a touch of feminine flair) features a water-repellent, breathable, stretchy twill fabric designed to keep you bone dry without overheating. Foul weather? Just zip up, adjust the cuffs and hood, and you're set. When the rain breaks, unzip, and the lapels naturally butterfly open for a natural, casual vibe that speaks to both your fashion-conscious desires and your understanding of the practical.
