The Hot Chilly's Micro Elite XT Women's Zip T is a heavyweight zip-neck base layer top built for cold days. It pairs a tough, smooth outer face with brushed fleece against the skin, and the zip collar lets you seal out the cold or dump heat in seconds.

Why we like it:

An interior wind flap sits behind the zipper, so the collar stays warm and draft-free when zipped all the way up on the chairlift.

Features and Functions:

Extended sleeves with thumbholes lock the cuffs in place under gloves and jacket sleeves, closing the gap at the wrist. The body is a heavyweight knit with a smooth nylon exterior for durability and easy layering and a brushed fleece interior for warmth. The fabric breathes well and pushes sweat outward, while four-way stretch and flatlock seams keep it comfortable through a long day. It also blocks UV, and Hot Chillys counts it among the warmest tops it makes.

Fit and Sizing:

Active fit through the torso and arms, close enough to sit smoothly under a midlayer.

Bottom Line:

Best for women who want their warmest base layer top with zip-neck temperature control for frigid resort days and early-season cold snaps.
