Senchi Designs Alpha 90 Crewneck - is an incredibly lightweight half-zip crewneck. The half zip is awesome when outdoors because it allows for a wide range of temperature management.

Minimal design, easy layering, extremely versatile. 

Made from Polartec® Alpha Direct 90, this crewneck is designed for maximum breathability and warmth retention. It's super breathable and surprisingly warm wearing under some wind blocking layer. If it's worn as an outer layer, you can hike with intensity and still maintain cooling. Also material wicks moisture away from your base layer very efficiently. 

Raglan sleeves and a mid-length collar. Packs down small and weighs next to nothing, making it a go-to option for backpackers, skiers, or anyone looking for a lightweight and functional layering piece.
