Rab Ascendor Hooded Men's Jacket When you're working hard, swinging ice tools, ascending steep slopes, or moving fast, the Ascendor is designed to regulate your temperature and keep you comfortable. Constructed with a grid fleece fabric that balances warmth, wicking, breathability, and mobility, it adapts to the conditions and your output, so you can make smooth progress. Stay cosy in the Rab Ascendor Hooded Jacket. A Thermic G fleece fabric has been used in the construction and is designed to regulate your temperature and keep you comfortable even whilst you're exerting yourself, so you can keep moving, make progress without stops, and enjoy every minute. The under-helmet hood fits snugly around the face and offers that extra boost of warmth when the wind picks up. Stretchy and slim-fitting, it's comfortable under other gear and fits easily under a harness with a longer length at the back to cover the hips. Low bulk and packable, it's a dynamic layer suited to high-energy ascents. A YKK VISLON centre front zip assists in putting the jacket on and off, and can also be used to regulate ventilation, with two hand and one chest pocket offering ample space to store your essential items. Elasticated cuffs and hem sit close to the body to seal in the warmth, while the longer back length provides full coverage. Completing the jacket are flatlocked seams, which reduce the chance of irritation caused by rubbing for improved comfort.
