TAUNUS 100 FZ W

I was skeptical about how well it would layer under my rain jacket, but the 3-in-1 system clicks into place perfectly and doesn't bunch up at all. The fleece is noticeably warmer than my old midlayer without being bulky.

The zipper runs smoothly even over the fleece's thicker seams, which I appreciate during quick layering changes. It pairs perfectly with my shell jacket for windy trail runs without feeling bulky underneath.

The 3-in-1 system is what sold me—it clicks into my rain shell in seconds, and the fleece alone is warm enough for crisp fall mornings. I’ve worn it on three hikes so far and it breathes better than my old midlayer, no sweat buildup on the climbs.
