Product Description You\'ll be amazed that a gilet this thin can keep you so warm. Wear it as your core base layer under a waterproof or on its own. Designed to squish down the large zip up chest pocket, Base is the perfect go-anywhere bodywarmer, as it takes up hardly any space, then puffs back up into shape when you want to wear it. The secret is in the filling, an exceptionally light thermal that traps pockets of air for natural insulation without any bulk encased in a smooth, silky, down-friendly fabric. Base has been designed with comfort in mind with a soft chin cover and shaped lower pockets that are just asking to slip your hands into to keep warm. There is light elastic at the cuffs and toggle adjusters at the hem, so you can tighten up to stay cosy when the wind is whistling. Destined to become your go-to sleeveless jacket for everything from a night out at the pub, walking the dog, it\'s also a brilliant mid-layer for a trek across the North Yorkshire moors and perfect for travel as you can use it as a small pillow on a long plane journey. As one of our signature pieces, this warm packable jacket has the TOG24 logo printed on the chest to represent our motto - Truth over Glory.
