Fully waterproof and very breathable weather protection that won't restrict the way you move. Perfect for demanding outdoor days.

Montane's Atomic II 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 (now with a dry-touch back for more comfort when you're in the wet), 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 mean that you can extend to full reach without losing coverage, and the tailored 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.

Subtle changes in the design include internal hood adjuster drawcords and newly styled reflective features, whilst the updated Dry touch fabric backing now gives you less of a cold feel when next to the skin.

  • 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

Waterproof, but not breathable, 24 August 2016
By HBM (Worcester)
Purchased for my D of E gold expedition in the Lake District. Unfortunately, the jacket is not very breathable, although it was humid it performed worse than cheaper alternatives worn by my friends. However, it is quite highly waterproof, withstanding 6 hours of driving rain.

Montane Men's Atomic II Jacket, 08 August 2016
By TheLaird (Inverness)
I purchased the Montane Men's Atomic II Jacket to go with the Montane Men's Featherlite Down Jacket.

I am now seriously worried as was standing at a music festival this weekend and had a 1 mile walk back to the car. Taking off my Atomic jacket I was shocked at the amount of condensation inside. It was like I had sprinted for a mile not walked it. I am now unsure about putting this on top of the down jacket.

Atomic II Jacket, 17 June 2016
By Johnny Bag (Oldham)
After returning a Rab Fuse jacket for not keeping me dry, I changed it for one of these.
First use - 15 minutes of light rain and I was drenched. I assume it let water in rather than keeping sweat in 'cos I'm definitely not that sweaty!
Total waste of money. Will return tomorrow.

Good jacket w/o frills, 31 December 2015
By Tbreckel (Suffolk)
Good basic shell for wet conditions. There are similar jackets with more pockets at lower prices. Still glad about my purchase.

Montane Atomic II Jacket, 24 December 2015
By Martin (West Midlands)
Fantastic fit, very comfortable, rain proof, reasonably wind proof, is not breathable.

Took a gentle stroll to work, shirt got damp. Took a more energetic hour long walk with the dog in moderate rain, all clothing damp, finally had an walk back from a train station (about 2 miles)..... Shirt got soaked.

On the bright side, the staff at Go Outdoors refunded me the money I spent on the item with no fuss, so thank you very much guys!

Was pretty disappointed by Montane as I have a prism Jacket and 25l Cobra and they are exceptional bits of kit.
