Product details

Cold-Season Layering Basics

This thermal base layer set is designed for consistent insulation for cold-weather wear. Its fleece-lined interior is designed to hold warmth while maintaining a compact and flexible feel suitable for varied activity. Made from an85% microfiber and 15% spandex, the material offers thermal layering compared with standard cotton blends. Flatlock stitching creates a smooth, low-profile seam structure that fits easily under outerwear. Intended for active layering or daily cold-season use.

Flexible Fabric Construction

Constructed with moisture-moving fibers, the material transfers moisture away from the skin surface for dry-feel wear. Its four-way stretch construction allows multi-direction flexibility without restricting movement. The fleece interior helps distribute insulation evenly, and the smooth exterior reduces friction when worn under additional layers. Whether used outdoors or indoors, the fabric maintains its structure after repeated washing.

Made for Regular Rotation

The set includes a pull-on closure for simple wear. Its compact fabric packs easily into luggage or gym bags for travel. Machine washable, it maintains elasticity and softness when air-dried. The snug fit helps keep the layer in place during everyday movement. Suitable as a base layer under winter jackets or for general indoor use.
