Shop Women's Base Layers From Top Brands Such As Smartwool, Icebreaker, Columbia and more! — 84 products / 661 models

The great outdoors is calling, but frosty mornings and mountain breezes shouldn't hold you back. Lay the foundation for any adventure with a women's base layer from OpticsPlanet. Our selection of performance-driven tops and bottoms wicks away sweat, traps warmth, and keeps you comfortable all day long.image

Whether you're carving fresh powder or scrambling up a peak during your next ski trip, shop Women's Baselayers from top brands such as Smartwool Women's Baselayers, Icebreaker Women's Baselayers that are designed for mobility. Look for merino wool base layers that are naturally odor-resistant and provide exceptional insulation, even when wet. Perfect for layering under ski jackets or for standalone wear on milder hikes. Flatlock seams prevent chafing, and stretchy fabrics move with your body for a full range of motion. Advanced moisture-wicking technology pulls sweat away from your skin, keeping you dry and comfortable during high-intensity activities. From lightweight options for active pursuits to cozy merino wool for ultimate warmth, we have a base layer to suit your needs and activity level.

Should Women's Baselayers Be Tight?

Women's Baselayers should ideally fit snug but not tight. Here's a breakdown of the ideal fit:

  • The base layer should skim your curves comfortably without sagging or bagging. This close fit lets the material wick sweat away from your skin effectively.
  • Your base layer should allow you to move freely and comfortably. Avoid anything that digs in or feels restrictive.
  • Think of your base layer as a second skin, not a compression suit.
  • If you're between sizes or prefer a looser fit, consider sizing up in your base layer.
  • Different materials may hug your body differently. For example, merino wool naturally has a more forgiving drape than synthetic materials.

By finding the right balance between snug and loose, you'll get the most out of your base layer in comfort and performance.
