Product Technologies

State of the art performance where you go, whatever the conditions.

HydroBlock® Pro


Obermeyer independently third party tests all of its technical fabrics for performance verification. Our high performance specialty fabrics use fully coated hydrophobic laminations and a superior DWR polymer coating for stain protection and coating integrity. HydroBlock® Pro resists up to 15,000mm before water penetration while allowing 15,000 grams of water vapor to pass through within a 24-hour time frame

Control Zone Ventilation™ with Mesh Gussets

Strategically placed adjustable openings and closures for core thermal regulation. Different placements allow you to release and control your body temperature. Underarm vent zips, thigh vents, jacket closures with mesh gussets all insure the greatest flexibility while maintaining waterproof/windproof closures to meet the most challenging weather conditions and aerobic exertion.

Integrated Powder Skirt with Snap-Away™ Feature

  • A powder skirt actually performs a couple of other functions beside keeping powder snow from reaching your core section. It has our innovative Snap-Away™ feature so you can remove the skirt for a more tailored fit.  When the skirt is snapped and in use it helps reduce heat lost from the bottom of the hem. Keeping you a bit warmer.
Track My Down

  • Obermeyer has partnered with Allied Feather & Down to provide the consumer a direct connection with our down's product cycle. Every lot of down receives a unique lot number which leads to an automated, scalable, and customizable lot page where consumers can learn about what is keeping them warm and comfortable.
