Columbia

Omni-Tech is Columbia’s waterproof and breathable fabric technology using a specialised membrane that blocks liquid water while allowing moisture vapour to escape, keeping you dry and comfortable.

Omni-Heat uses tiny silver reflective dots on the fabric’s inner lining to reflect body heat back toward you, providing lightweight and effective insulation without bulk.

Omni-Heat Infinity is the next-generation version with gold reflective dots that trap more heat, offering enhanced warmth compared to the original Omni-Heat technology.

OutDry Extreme is a waterproof technology where a water-resistant membrane is bonded to the outer fabric layer, preventing water from penetrating at all and reducing waterlogging.

Omni-Wick technology pulls sweat away from your skin and spreads it across the fabric surface for quick evaporation, helping regulate body temperature and keep you dry during high activity.

Omni-Shield is a water and stain-repellent finish that helps keep your gear clean and dry by causing liquids and dirt to bead and roll off the fabric's surface.

Columbia uses a range of insulation materials, from synthetic fibres to responsibly sourced down, combining lightweight warmth with durability for various conditions.

Yes, Columbia’s Omni-Tech and OutDry technologies are designed to provide both waterproof protection and breathability, allowing for comfortable moisture management.

Waterproof ratings are measured by hydrostatic head pressure, with Columbia fabrics ranging typically from 10,000 to 20,000 mm, indicating high levels of water resistance suitable for severe weather.
