Arcteryx Mens Atom SL Hoody Black

Season:ZZZ Discontinued

Brand:Arcteryx

Code:17305-BLA-

What is the Atom SL?

The Atom SL is the lightest weight synthetically insulated jacket from Arcteryx. It's perfectly suited to cold, fast-paced mountain adventures like running and biking but also works well as an extra, light layer on chillier summer evenings.

What is the Atom SL made of?

Insulation: The Atom SL has 40g/m² of Coreloft Compact in the body to maintain core temperature during mid to high output activities. Coreloft is a synthetic insulation that is similar to Primaloft. However, it has been developed by Arc'teryx to be more durable. Not only is it more durable, but the synthetic fibres have also been siliconised to further increase breathability by reducing the fibres ability to hold onto moisture.

Outer Fabric: The outer is a combination of a tough 20 denier, 100% nylon fabric everywhere apart from the air permeable side panels and underarms. This is made from Torrent fabric that has an antimicrobial Polygiene treatment to avoid the build up of nasty smells and is also stretchy to give a low profile fit that improves the overall ventilation of this brilliant looking jacket.

What are the features?

The arms are lined with a 100% polyester mesh to help wick moisture away from your skin and to avoid that annoying feeling when the outer fabric starts to cling to damp skin. A low profile, non insulated hood adds protection from the wind without over heating and the No Slip Zip works like a series of speed bumps so it won't work itself undone so when you need to keep in more heat when needed. Then finally you have 2 zippered hand pockets, luxurious shaped stretch fleece cuffs and adjustable hem to seal you inside and trap more heat.

How does the Atom SL fit?

This garment has the Arc'teryx “Trim Fit”. Trim fitting garments share motion-friendly traits with the “Regular fit”, but are patterned with lower volume for reduced bulk. The trim fit is sized for a base layer and a trim synthetic or down filled mid-layer. Check out the link below for exact sizing measurements.

Where does the Atom SL fit in the layering system?

The Atom SL is a lightly insulated jacket that works well as a stand-alone jacket on still, chilly summer nights, but can also be layered up under a shell in colder, damp conditions.

How Should Your Insulated Jacket Fit?

Insulated jackets are pedantic little things. Too tight and you'll compress the insulation and limit the warmth capabilities of your brand new jacket, too loose and you'll spend hours warming up the dead space inside the jacket. Getting the correct fit isn't just about aesthetics, it will determine how warm you are.

The Incorrect Fit
Too loose: A jacket which is too loose will keep you relatively warm, however it will take far longer to do so and will waste large amounts of your precious energy. An insulated jacket works by trapping the natural heat that your body gives off in the fibres of the insulation; this creates a micro-climate inside your jacket, keeping you warm and toasty. If your jacket is too loose, heat will be able to escape through the hem, the sleeves and the neck of the jacket; it's a little like sticking the heating on in your car with the windows cracked open - it will heat up, just incredibly slowly.

Too tight: A jacket which is too tight is arguably worse than one that is too loose. If your jacket is far too tight, the baffles can compress to a point where the insulation can't loft effectively, limiting the amount of warmth it can trap. Essentially, it won't work!

The Correct Fit
It's a tricky one to explain, but it's somewhere in the middle. You've first got to consider how many layers you'll tend to wear underneath; will you have just a t-shirt then the jacket, or possibly a baselayer, midlayer and then the jacket? When you've figured out your layers and you've popped your insulated jacket over the top, you shouldn't have any dead space inside. The cuffs and hem should be comfortably sealed around your waist and wrists with room to move. You should be able to lift an arm up above your head without the hem of the jacket lifting more than an inch or so, and the sleeves should be long enough that when carrying out the same motion, they aren't mid-way up your forearm. Your shoulders and chest area should have enough room so that your hands can touch behind your back without feeling restricted.

Additional Information
Lastly, consider which activites you'll primarily be carrying out while wearing the jacket. Are you primarily using it as a winter climbing piece, or an everyday/dog walking jacket? You'll find that technical climbing jackets tend to feature a shorter cut, while urban and casual jackets feature a longer cut to offer additional warmth with less mobility.
