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 ripstop 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 new features may go unnoticed to the untrained eye but they add so much to this already brilliant jacket. Firstly Arcteryx has given you an improved fit and a longer body for better coverage and insulation. Secondly, the Cerium LT now features drawcord at its hem which allows you to seal out the cold winter air, and finally, the added inner security pocket is perfect for keeping phones and spare batteries in so they won't be susceptible to cold temperature power drainage.

The result, a down jacket that fits and feels fantastically well, performs in all mountain environments and looks brilliant.

Care & Advice

How to wash your down products

Having spent years talking to people about down products, whether that’s a jacket, sleeping bag or even a pair of slippers, very few have had the confidence to go ahead and wash the product on their own, especially when they have just spent an arm and a leg on it. This small guide is here to explain that it’s not as daunting and utterly terrifying as it first appears.

Step one: Before you even get near that washing machine, wipe off any excess mud or dirt that may be lingering on the surface of the jacket, as this will clog up the washing machine, eventually rendering it useless.

We recommend the use of Nikwax Down Wash Direct for down products as it’s one hundred percent environmentally friendly and will wash and re-proof the garment without the use of bleach or any other nasty chemicals. What household washing agents can (and often do) is remove the water repellent coating on the fabric of the jacket, whilst also damaging the delicate array of feathers inside.

Step two: We’ll assume in this instance that you’ve been washing other products prior to your down jacket and have used a bleach based detergent. Therefore it’s a good idea to run the washing machine for half an hour or so without anything inside to rinse it clean before adding the Nikwax or putting the jacket in. Also, don’t forget to remove the detergent drawer to give it a wash inside, outside and behind, as detergent can clog up and still enter the washing machine if not cleaned out thoroughly. This ensures that any remnants of detergent are removed and that the Nikwax products will work effectively.

Step three: Set the washing machine to a cold wash (check the garments care label, most tend to be around 30°C) and as delicate as possible. Most washing machines have a “wool” cycle which is ideal.

Step four: If using Nikwax Down Wash Direct, place 100ml in either the tray or directly into the washing machine inside a small pot/ball. If you choose to use another washing product, place the appropriate amount in the machine in the same way.

Step five: Set the washing machine to run on a slow cycle, allowing plenty of time for the jacket to soak up the cleaning/re-proofing product. Most washing machines will have a pre-set time for different washing cycles.

When the cycle has finished be prepared for a shock, your precious bit of kit will come out looking like a soggy ball of material. But don’t worry, you haven’t ruined it, it’s just that all that fluffy down insulation has become water logged and has clumped together. The trick is to now get all that down nice and dry to reinstate its superb insulating properties. Simply hanging it up in a warm place will not work that well. It will take days to properly dry and you will have to constantly break up the clumps to get it thoroughly dry. The best way is to use a tumble dryer; either a domestic one for smaller items or a commercial drier for sleeping bags.

Step six: Pop the garment into the dryer and make sure to select a low heat; a high heat runs the risk of melting seams and fabrics within the garment. It sounds weird, but shove a few tennis balls into the drier with the garment; the tennis balls will bounce around and help to break up the clumps of down. Every 20 minutes, pull the jacket out of the dryer and lie the jacket down on a table. Run your hands over the jacket until you find a 'clump' or ball of down; tease apart this down clump and spread it evenly into the baffle. Once you're confident you've pulled apart every clump to the best of your ability, stick it back in for another 20 minutes. Keep repeating this until there are no more clumps left. 

Step seven: When the cycle has finished and you are sure that you have got the garment as dry as possible, hang it up in a warm dry place, an airing cupboard is ideal, for 24 hours. This drives out the last of any dampness and allows the down to loft fully. Take it out and give it a good shake and, hey presto, it’ll be as good as new.

    Arcteryx Mens Cerium LT Hoody Neptune ,  On

    Excellent jacket. Unbelievably warm for the weight. It is more expensive than some of the other more common names, but it is a quality garment, that still looks new after 2 years constant wear. Well worth the extra money in my opinion and you dont see too many around. I was also surprised by how durable it is, considering the weight. Just fabulous bit of kit.

    Great jacket, very light, you can roll it up completely so that it doesnt take up any space in your luggage, yet it provides a fair protection against elements. Ideal everyday item for British winters with temperatures around zero, you can combine it with other garments in colder climates.

    Arcteryx Mens Cerium LT Hoody Neptune ,  On

    Bought to compliment a hard shell and Arc’teryx Nuclei SL in really cold conditions. Used it for travel to and from Chamonix, skiing and ski-touring In some really cold windy weather. Wore it skiing in cold windy weather and it was fantastic. Only when wearing a hard shell over it did I get a bit sweaty but I preferred this to being cold! Incredibly light for the warmth and easy to pack down or have clipped to harness when making stops. Definitely my new favourite jacket.

    Brilliant. Used skiing, ski-touring and even under a hard shell in some really miserable alpine weather- bit sweaty but once hard shell was off ‘ventilated’ and felt dry very quickly. Incredibly light and easy to pack/clip to harness. Feels durable and had no concerns wearing it skiing as an outer. My new favourite jacket.

    Only just bought as alternative to Rab micro that was way too baggy in the body. This fits my 6ft1" long limbed lanky husband perfectly; its pricey though, so hope it wears well.
