Ideal for crisp days when you don't want to start cold or overheat after a mile, the men's REI Co-op Swiftland Thermal Running Half-Zip's grid-back fleece is warm without trapping excess heat.
- This pullover can be worn next to skin, but it really shines as an adaptable mid or last layer
- Lightweight grid-back fleece is warm yet allows excess heat to dissipate, preventing moisture buildup that can quickly bring body temperature down and ruin a run
- Made with yarn that uses LanzaTech carbon-capture technology
- LanzaTech is a biochemistry company that's developed technology to capture carbon emissions from industrial sites, such as steel mills, before they enter the atmosphere
- These carbon-rich gasses are then converted into ethanol, which can be used to manufacture new materials like polyester
- Ripstop nylon overlay at front and back yoke adds a layer of durability; nonfluorinated durable water repellent (DWR) on the overlay helps moisture bead up on the surface
- Half-zip design lets you dump heat for immediate ventilation
- Underarm gussets for ease of movement
- Fold-over cuff mitts and thumbholes let you adjust coverage to match conditions
- Secure zippered pocket at chest for phone, keys or card
- Reflective details
- Locker loop
- Back length: 29.25 in.; Tall sizes: 31.25 in.
- Machine wash cold; do not use bleach or fabric softeners; tumble dry low
- REI is Climate Neutral Certified; as we work to actively reduce our footprint, we measure annual carbon emissions and purchase an equivalent amount of verified carbon credits
- Contains materials that meet the bluesign® criteria

Sizing Notes
Measurements are stated in inches unless otherwise indicated.
SHORT: Some pants are available in short sizes, which generally means an inseam that is 2.5 inches shorter than regular sizes.
TALL: Some pants, shirts, jackets and parkas are available in tall sizes, which generally means an inseam that is 3 inches longer and a rise that is 1 inch longer, a shirt or jacket body that is 2 inches longer, a parka body that is 2.5 inches longer and sleeves that are 2.5 inches longer than regular sizes.
Capri or cropped pants have an intentionally shorter inseam—reference the technical specs instead of this chart.
Inseam is measured to the floor.
