The Cerium LT Jacket is a specialist lightweight down jacket that can be used as an active user’s winter mid layer or as a standalone piece in cold dry conditions. It weights next to nothing, has clever mapped insulation, and can be stuffed into its own stuff sack for easy storage.
Beautifully made, as you would expect from Arc’teryx, and impressively light. Traditional down jackets are made lighter by simply reducing the amount of down and using super lightweight, fragile materials. Arc’teryx however have stuffed the Cerium with 850 fill power European Goose Down and given it a high tenacity face fabric. Weight reduction has been achieved through ingenious engineering techniques. For example, the baffles on the elbows are narrower on the inside because your arm is naturally bent, so that area needs less fabric, the hem draw cords are reduced and only pull in the back of the jacket and the whole jacket is anatomically cut to reduce surplus fabrics.
Arc’teryx have strategically placed Coreloft insulation in areas that receive the most moisture and are affected by compression. Therefore, the shoulders are Coreloft insulated as are the hem, sleeves, and underarms. This retains warmth even when wet and resists compression better than natural down. you get the best of both types of insulation, unrivalled warmth, and comfort from the down in the main body and protection from Coreloft in strategic areas.
The outer is a 10-denier mini rip stop Nylon which has been treated with a DWR (durable water repellent), so it is tough, wind resistant, highly breathable and has a smooth feel and soft handle.
The result, a down jacket that fits and feels fantastically well, performs in all mountain environments and looks brilliant.
