Our sleeveless lightweight base layer built with Polartec Delta? is the perfect building block under your jersey. The fabric performs extremely well at dispersing moisture which helps keep you comfortable. The flatlock seam construction avoids any uncomfortable seams next to your skin, and to top it off, it??s sewn right here in California using deadstock fabric (more on that below)...

What's deadstock? It's fabric that was somehow deemed "extra", so instead of milling new fabric for this base layer, we found fabric that was already available with no home, kind of like a rescue dog.
