A highly breathable active layer built around an innovative fabric
Sambob says:
The SAMBOB Octa hoodies are made from a unique ultralight fabric made by Teijin (based in Japan). With a brushed fleece interior face and a flat mesh exterior face, this fabric stands to rival Polartec Alpha in its warmth to weight ratio, while also proving to be more durable against snags and tears. This fabric is semi-transparent and extremely non-wind resistant, but acts as a perfect active layer fabric.
Our Verdict
The Sambob Octa Hoodie is a lightweight mid-layer designed for year-round insulation. At 134g (Medium), the Octa Hoodie provides surprising warmth for something so light without feeling bulky or restrictive.
The defining feature is the Octa fabric, which utilises a unique hollow-core polyester fibre that traps warmth while keeping overall weight low. The brushed inner face feels soft against the skin, while the open, mesh-like outer face allows moisture and excess heat to escape quickly. The result is a fabric that dries fast, breathes extremely well and continues to insulate when damp, though it is air-permeable, so a windproof shell is advised.
The fit is relaxed but tidy, so it layers easily over a base layer or beneath a shell. The hood sits comfortably and can be adjusted with a simple drawcord. With the hood down, tightening the cord cinches the hood around the neck, creating a warm, snood-like seal that traps heat at the collar. With the hood up, it can be left open for ventilation or cinched closer around the face in colder weather. That single elastic adjustment effectively gives four distinct configurations for managing warmth.
Durability is better than many airy insulation fabrics. The Octa material resists snagging more effectively than similar high-loft materials. It is a focused, efficient layer that suits hikers who prioritise breathability and consistent comfort over static warmth.
