Damen-Fleecejacken & Zwischenschichten

A mid layer's job is to trap warmth generated by the base layer beneath it, so fabric choice matters more than styling. A technical fleece, such as Polartec® High Loft™ or Polartec® Power Grid™, offers a strong warmth-to-weight ratio without excess bulk, while a lightweight insulated layer works well where pack space or mobility is a priority. Fit should sit close enough to layer cleanly under an outer shell, without restricting movement through the shoulders and arms. The right mid layer disappears into the system rather than fighting against the layers around it.

The 3-layer rule refers to the base, mid and outer layer system that underpins effective cold-weather dressing, regardless of gender. The base layer manages moisture against the skin, the mid layer insulates and traps warmth, and the outer layer blocks wind, rain or snow. Each layer has one job and should be chosen for that function alone; adding bulk in the wrong layer, an insulated outer instead of a weatherproof shell, for instance, undermines the whole system rather than improving it. Proper fit through each layer, especially for women, ensures no gaps open at the waist or cuffs where the system is designed to seal.

Neither extreme. A mid layer needs to sit close enough to layer cleanly under an outer shell without adding bulk that restricts movement, but loose enough to trap a thin layer of warm air, which is how insulation actually works. Too tight, and the fabric compresses, reducing its warmth; too loose, and it bunches under the outer layer, creating cold spots and restricting mobility. The right fit allows a full range of motion while still doing its job of holding heat close to the body.

For most three-season hiking the Phalanx Fleece is the go-to, a versatile mid layer that balances warmth and breathability across a wide range of output levels and conditions. For colder, slower-paced days or high-altitude use where static warmth matters more, layering a heavier fleece or an insulated gilet over a lighter base gives you more thermal performance without the bulk of a full insulated jacket. Browse the full women's mid layer range to find the right weight for your intended use.

Yes. Our women's mid layers are built from women's-specific patterns, not adapted from men's cuts. The fit accounts for differences in shoulder width, chest, waist, and hip proportions so the garment sits correctly as part of a layering system rather than bunching, gaping, or restricting movement in the wrong places. Proper fit in a mid layer matters more than people expect. A poorly fitting fleece compresses unevenly under a harness or shell, creates cold spots, and limits the range of movement you need on technical terrain. Women's-specific construction solves all of that.
