Our Ultralight Octa® Fleece Hoody isn't just any hoody, it's a game-changer. Crafted from cutting-edge Octa® fleece, this hoody is incredibly lightweight and durable, yet boasts an unmatched warmth-to-weight ratio.

The soft fluffy interior feels like a cozy hug, while the half zipper design allows you to regulate your temperature and slip the hoody on and off as the weather changes. The fitted hood keeps the cold off your ears, and the roomy kangaroo pocket is tall enough to access while wearing a backpack belt. Perfect for warming your hands or holding your trail snacks.

Whether you're scaling a mountain or chilling at a campsite, this hoody is ready to conquer the backcountry in style.

  • Octa fleece offers exceptional warmth at an incredibly light weight, making it an advanced alternative to traditional fleece. It excels as an active insulation and performs well in a range of temperatures from the 30F's (0 C) to the upper 60F's (20C) while moving.
  • The interior of the Octa features a fluffy next-to-skin, brushed surface that traps air to keep you comfy and warm.
  • Add a Zpacks Wind Shell Jacket to block the breeze and push your layering system into even colder temperatures.
  • The mesh exterior is extremely abrasion resistant, providing better durability than other ultralight fleece options. It also doesn't collect crud like other fleece that is fuzzy on the outside.
  • Half length zipper allows you to regulate your body's temperature and slip the hoody on and off as the weather changes.
  • Spacious kangaroo pocket helps keep your hands warm or store items that you'd like to reach quickly like gloves. The pocket is tall enough to allow easy access while wearing a backpack belt.
  • Fitted hood warms up your ears on chilly mornings.
  • Integrated thumb holes prevent your sleeves from riding up, keep your hands a little warmer, and provide sun protection for the top of your hands.
  • The sleeves provide excellent range of motion while eliminating a top shoulder seam that could rub against your backpack straps.
  • Elastic at the hem and at the wrists helps trap heat and prevents the hoody from riding up.
  • A gentle dove tail shape on the rear of the hoody helps provide coverage when riding a bike or reaching above your head.
  • Sizes are US Men's, however the athletic fit and stretchy material work well for women's figures as well.
  • The material is stretchy, allowing it to comfortably conform to your body's movements.
  • UPF 40+
  • All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.
