POLARMAX Active Stretch Base Layer Midweight Men’s Top

POLARMAX Active Stretch Performance Base Layer Midweight Men’s Top — Midweight Crew (polyester/spandex stretch knit)

Warmth that moves with you—built to keep you dry, flexible, and comfortable in cold conditions.

This 4-way-stretch POLARMAX midweight base layer top (crew neck) is crafted from a moisture-wicking performance knit and built for active cold-weather wear. Featuring a brushed interior for warmth and a smooth exterior that layers cleanly, it delivers a mobile, close-to-body fit for long days on the job or in the field.

Product Description

A premium, active-stretch base layer made from a quick-dry polyester/spandex knit for dependable warmth, breathability, and mobility. The brushed inner face traps heat; the smooth outer face slides easily under hoodies, bibs, and jackets. Flatlock seams reduce chafe, while an anti-odor finish helps keep you fresh through repeat wears.

Key Features

• Size: Midweight crew — ideal as a first layer for work, hunt, and cold-weather training.

• Material: Polyester/spandex performance knit — stretchy, breathable, and fast-drying.

• Construction: Brushed-back interior for warmth; flatlock seams and set-in sleeves for comfort and range of motion.

• Mounting: Layer-friendly crew neckline; low-bulk profile that fits cleanly under outerwear and PPE.

• Hems & Stitching: Reinforced cuffs/hem with durable flatlock stitching to minimize irritation.

• Finish: Moisture-management + anti-odor treatment for extended wear.

• Care: Machine wash cold; tumble dry low; do not bleach or use fabric softeners.

Why It Stands Out

Active-stretch fabric keeps you warm without restricting movement, and superior moisture control helps regulate temperature as your effort ramps up—perfect for fluctuating winter conditions.

Perfect For

• Tradesmen layering under hoodies, bibs, and shells

• Hunters and hikers needing mobility with dependable warmth

• Warehouse, delivery, and shop crews moving between indoors and outdoors

• Everyday winter wear when you want heat without bulk
