Under Armour ColdGear Reactor Run Hybrid Running Jacket

It's the lightweight jacket you can actually run in. That's because the insulation adapts to your activity level, so as you heat up, it lets out warmth.

Designed to keep you comfortable, warm and dry on race day, the Under Armour ColdGear Reactor Hybrid Jacket has been constructed using UA's signature Storm Technology. This unique water-resistant finish repels light rain and snow whilst remaining highly breathable and lightweight - you can give your best performance even in testing weather conditions. The breathable nature of the fabric allows cool air to flow into the garment whilst, at the same time allowing hot humid air to escape so your skin can have a perfect microclimate to thrive in. The lightweight fabric also remains soft and flexible for superior mobility; the fabric allows you to achieve a full range of motion because your clothing choice should never inhibit your natural movements. ColdGear technology has also been used within the Under Armour Hybrid Jacket to keep you comfortable and warm on cold weather days. The generously warm, fast-drying interior helps you to stay warmer for longer by absorbing and retaining your own body heat when the mercury drops. ColdGear Reactor is a lightweight, intelligent insulation that adapts to your activity level for the right breathability and warmth for what you're doing. This innovative technology keeps you as warm as possible when there is little to no movement, but as soon as you get moving and the blood starts pumping, the technology works to dump that excess heat that is not needed anymore.

The stretch woven fabric and lightweight quilted insulation helps to keep you warm without weighing you down whilst the 4-way stretch fabric moves better in every direction. The fabric moves as you do to ensure freedom of movement because your clothing choice should never inhibit your natural motion. Ergonomically shaped cuff with built-in thumbholes to trap warmth and keep sleeves in place. A full zip exists for complete temperature control; in colder conditions, it can be worn up to seal in escaping heat or when the temperature begins to rise it can be worn down to release an intolerable heat build-up. The low profile collar construction sits comfortably against the skin to reduce chafing and irritation plus, a dropped hem provides added coverage. Secure-zip hand pockets store your essentials items and can be used to warm your hands when temperatures drop. Completing the ColdGear Reactor Run Hybrid Jacket are reflective details which increase your visibility to passing vehicles on late night adventures.
