What is the Atomic Jacket?

The legendary Atomic Jacket is a stunning jacket for the price. Featuring a Pertex Shield membrane, an updated fit, a fully adjustable hood and ventilating pit-zips, it's the ideal piece for walking, trekking, backpacking, travelling, the list goes on!

What is it made from?

Starting from the outside, the Atomic features a durable 40D nylon outer fabric which protects the membrane (and you) from rucksack straps, abrasion and general wear and tear. This outer fabric is then coated in a durable water repellent coating to allow water to bead off the surface, increasing breathability. Underneath this, you get a fully waterproof, windproof and breathable Pertex Shield membrane which does most of the hard work against questionable weather conditions. Finally, the inner fabric is a Dry Touch backer. This backer doesn't technically offer any performance benefits, however it feels lovely and soft next to skin opposed to the inner fabrics of old which felt a little like wet dishcloths. 

What are the features?

Features wise, you get a fully adjustable roll-away hood with a wired peak, a nice high collar when the hood is rolled away, pit zips to dump large amounts of heat when working hard, two mesh-lined hand pockets which will also fit most maps, adjustable cuffs, an adjustable hem and reflective details. Essentially, you get every feature you could possibly wish for during walking, trekking and travel use. 

How does it fit?

The Atomic has always had a great fit, but for this year it has been refined even further. The length is nice and long in the body and arms, and the overall fit isn't slim, nor is it baggy, it sits perfectly in the middle. You can easily fit a few insulated layers underneath, however it feels brilliant with just a baselayer too.

Where does it fit in the layering system?

It's designed as an outer layer which is where it will be used 90% of the time. You can stick a synthetically insulated jacket over the top when you stop for lunch to offer additional warmth, but the Atomic works best as the layer on the outside of your layering system.


For the walker, trekker, traveller or commuter, the Atomic jacket is all you'll ever need! Sitting around the £100 mark, the Atomic looks and feels twice its price and will perform reliably and effectively for years.

Care & Advice

Care and maintenance

To keep your outdoor clothing and equipment in tip top condition and performing to its maximum we recommend the use of Nikwax products. We have been using Nikwax products since day one (26th March 1986) and have found them to be totally reliable, dependable and effective. Today’s Nikwax treatments contain environmentally friendly elastic water-repellent polymers that bond to fabric fibres, leaving the spaces between open and breathable. These stretchy polymers are able to stretch and move with the fabric so they stay put for longer and work better.

Nikwax treatments will not change the look or feel of the fabric and they are all water based, environmentally safe, non-flammable and contain no nasty Fluorocarbons. Nikwax products can be used to clean, re-proof and revitalise all your outdoor technical clothing and equipment.

Waterproof breathable clothing has a durable water-repellent (DWR) finish applied to the face fabric during the manufacturing process. The DWR forces water to bead up and roll off the surface therefore preventing the fabric from absorbing moisture. If the outside of your jacket is soaked in a layer of cold water, the warm damp air within can’t escape and will condense on the inside. This makes the jacket feel cold clammy and can make you think that it’s leaking. The DWR finish is not permanent and needs to be maintained and revitalised to optimise performance.

This three layer waterproof jacket should be cleaned regularly with Nikwax Tech Wash; I wash my jacket about once a month, or more often if it gets really filthy. Regular washing with Tech Wash will maintain the DWR for longer and remove salts and oils that can contaminate the fabric, and it will keep your lovely jacket clean and smelling fresh. Washing can be done in a machine according to the manufacturers care guidelines (on the internal label). First clean out any detergent and conditioner residue from the machine dispenser and then add the required amount of Tech Wash and away you go. Hand washing is also suitable but be sure to rinse the garment well.

When you notice that rain/water is no longer beading up and rolling off it’s time to re-proof. Nikwax TX Direct will re-instate a long lasting DWR to completely rejuvenate your jacket. Re-proofing can also be done in the machine once a garment has been washed. Just add the TX-Direct and use the same programme you used for washing. You can also use the spray-on product on a damp garment that has just been washed.

You wouldn’t buy a Ferrari and never have it serviced, so make sure you regularly wash and re-proof your quality kit.

Excellent customer service. Really detailed easy to understand product descriptions on the Trekitt website, and gear reviews on the Trekitt YouTube channel made it so easy to choose the right backpack for me.

Amazing service! Very helpful in regards sizing and what most matched my needs, despite this being done over the internet. YouTube videos of products being examined are very useful also. Would definitely use again, very fast and efficient delivery. Brilliant! Highly recommended!
