A waterproof and breathable shell that keeps you covered but lets you move freely, lending itself to any demanding outdoor pursuit.

Montane's Atomic Jacket is a versatile lightweight mountain rain shell that's fully waterproof, windproof and breathable, and cut to let you move without restriction.

Made using remarkable PERTEX® Shield fabric, its hardwearing nylon face also boasts a durable water repellent (DWR) finish that makes rain droplets bead and run off before they get a chance to penetrate the fabric.

Its 'mountain cut' means it's useful for any demanding outdoor pursuit. Articulated arms allow for high-reaching movement without you losing coverage, and the tailoring works so that the hem won't lift when you stretch yourself.

The cleverly designed hood has three adjustment points and a wired peak, and an internal tab lets you lock it down and roll it away if it's in your way. A soft fleece chinguard around the face and mouth area keeps you comfortable when you need to hunker down inside the collar.
  • The two mesh vented hand pockets are positioned where they won't get in the way of your harness or backpack straps.
  • Microtaped seams throughout increase the breathable surface area
  • Full length YKK front zip with internal storm flap and rain drain
  • Hook-and-loop adjustable cuffs with mitt grab tabs for easy use with gloves or mitts
  • Single hand operated adjustable, elasticated drawcord hem prevents weather entry and heat loss
  • Subtle SCOTCHLITE™ reflective details for mountain safety

Neat functional jacket, 08 February 2016
By flyguy (Liverpool)
This is a well made jacket with decent features. The cut/fit is excellent... slim-ish but not figure hugging with plenty of room for a couple of layers underneath. It's very waterproof and water beads off it nicely. First time I used it I was caught in a torrential downpour for 45 mins or so and I stayed dry. Not the most breathable of jackets but what do you really expect at this price point. I'd say breathability is acceptable if you just want a jacket for occasional light use and/or an emergency shell. If you want a more breathable jacket, then go spend £250 plus! The jacket packs well and is very light. I would recommend for short walks/low intensity activity.

packs light and small, but not breathable, 01 February 2016
By adibrandh (derby)
As others have said, this fabric doesn't breath at all.. not even in the slightest. You'll be just as wet from the condensation build up as you will from the rain.
Other than that, it packs down well, is light, and is a nice little jacket. If you're the type of person who doesn't expel moisture through your skin, you'll be fine.

Montane Atomic Jacket, 27 January 2016
By SimonT (Torquay)
The jacket is not breathable at all. When you take it off there is always a thin film of sweat on the inside. My Gore-Tex jacket is much more breathable.

Waterproofing is good, the jacket is put together well, nice features.

However, due to the breathability of the material used, I cannot recommend it.

So disappointed..., 30 December 2015
By normski (Skipton)
I've been so excited about this jacket since buying it and I'd decided I loved it.... You see, I bought it 'from the kids' to me for Christmas!! Win win!!
We all know we had some heavy rain in the North West around Christmas and the first opportunity I had I used it on a very easy dog walk. Really easy!!
The heavy rain didn't get through at all, it beaded with beauty, but God I got wet and it was sweat!!
What a shame ... I'd hate to think how this would perform in the hills carrying a pack or on something really tough. I do sweat a little more than a slim lady standing still, but this is a serious issue and I need to go back to store with it.
I just hope Go Outdoors or Montane will be understanding of the problem.

Very good jacket but...., 03 November 2015
By Ben (Warrington)
I really really want to love this jacket. It fits well, great price completely far so good eh? one problem....although advertised as breathable.....I have found it not to be breathable AT ALL. I'm a long distance runner, so when I'm on a long run, I'm not working at a high intensity, it's just about getting the miles in.....if I wear this, I get absolutely drenched in sweat (so much so that it drips down the inside of the jacket) despite the fact that I'm not working at high intensity and the jacket is supposed to be breathable. Even despite this pretty fundamental problem, I still do like the jacket and would definitely rely on it to keep me dry if I was walking, but nothing more intense than that as I end up getting soaked with sweat anyway and it defeats the purpose. Wish I could give it more stars as I say, I do really like it. Hope this helps someone make a buying decision.
