The Thorium is best described as a general multi-purpose down jacket that can be used as a winter mid layer or just as a super warm & cosy everyday jacket. The boffins at Arcteryx have cleverly combined natural down with strategically placed synthetic insulation to reduce weight, reduce compression & improve performance. The Thorium is beautifully made, as you would expect from Arcteryx, but the really clever thing is the way that they have made the jacket so light. Traditional down jackets are made lighter by simply reducing the amount of down & using super lightweight, fragile materials. Arcteryx however have stuffed the Thorium with 750 fill power European Grey Goose Down & given it a robust 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 & only pull in the back of the jacket & the whole jacket is anatomically cut to reduce surplus fabric. The Thorium also uses strategically placed Coreloft siliconised polyester synthetic insulation in areas that receive the most moisture & are affected by compression. The hood is Coreloft insulated as are the shoulders, hem, sleeves & underarms. Coreloft retains warmth even when wet & resists compression better than down. So you get the best of both types of insulation, unrivaled warmth & comfort from the down in the main body & the protection from Coreloft in strategic areas. The face fabric is a 40 denier mini rip stop taffeta Nylon, it has been treated with a DWR (durable water repellent) & is wind resistant & highly breathable. The end result of all this technology & Arcteryx gorgeousness is a down jacket that fits superbly, feels fantastic, performs in all mountain environments & looks brilliant. 750 fill power European Grey Goose Down Coreloft 140 gsm insulation Coreloft 80 gsm insulation Moisture-resistant outer face fabric Breathable Insulated Lightweight Compressible & packable Wind resistant DWR finish (Durable Water Repellent) helps bead water from fabric surface Down Composite Mapping strategically places Coreloft synthetic insulation in areas where moisture may build up.
