Zpacks Octa Fleece Thermal Bottoms
Zpacks Octa® Fleece Thermal Bottoms beat the warmth and weight of all other long underwear in their class. Designed to be worn under your hiking pants in frigid weather, under shorts in cool weather, or worn as an ultralight sleep layer, these leggings are unmatched when ounces count.
Octa® Fleece features a soft, fluffy interior that traps warmth and keeps you cozy, and an abrasion-resistant exterior that withstands wear and tear.

- Our 2.35 oz/sqyd Octa® fleece offers exceptional warmth at an incredibly light weight, making it an advanced alternative to traditional fleece.
- Octa® filament has an octopus-like cross-section with 8 projections, which create air gaps that enhance heat shielding and insulation properties. That unique fiber structure makes Octa® fabrics roughly 50% lighter than regular polyester materials of similar thickness.
- The interior of the Octa® features a fluffy next-to-skin, brushed surface that traps air to keep you comfy and warm.
- 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.
An elastic waistband offers a comfortable fit for a range of waist sizes.
The gusseted crotch enhances your range of motion and prevents restriction when stepping up and over tall obstacles.
Convenient overlapping fly opening.
Pairs nicely with our Octa Fleece Hoody and Octa Fleece Hat as a sleep layer.
All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.
