What it is

Alpha is a uniquely designed fleece fabric that optimizes warmth and breathability, making it the ideal active insulation layer. With lofted fibers connected to a lattice of threads, Alpha continuously releases body heat, preventing discomfort while active.

Alpha's top attributes

  • Regulates warmth

    Lofted fibers trap body heat while simultaneously releasing excess heat before it builds to discomfort.

  • Lightweight

    Average garment weights range from just 3.5 to 7.5 oz across styles.

  • Compressible

    Low weight and open knit mean Alpha packs down to nothing — a perfect layer on the go.

  • Hydrophobic

    Doesn't absorb sweat or water.

  • Fast drying

    As a porous fabric, Alpha dries incredibly quickly.

  • Cozy as can be

    The comfort of this fabric cannot be denied.

Which weight is right for you?

Sambob makes hoodies in three weights of Alpha — 60, 90, and 120 grams per square meter (gsm). Whichever you choose, you're getting a very light, packable layer that will be cozy.

  • 60 gsm — Ultralight

    ~3.5 oz hoodie

    A very lightweight layer for summer, morning runs, or an evening chill in the air.

  • 90 gsm — Midweight

    ~5.5 oz hoodie

    Popular with day hikers, runners, and thru-hikers. Warm enough alone, and pairs well with a wind or rain shell for extra warmth.

  • 120 gsm — Heavyweight

    ~7.5 oz hoodie

    For early spring or late fall hiking, or as a toasty layer under a puffy in the depths of winter.
