With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Mammut Mens Aconcagua Light ML Hooded Jacket Gentian

Season : Sale

Brand : Mammut

Code : 1014-00691-5213-

What is it?

The Aconcagua is a lightweight midlayer that's fast drying, comfortable, low profile and moisture wicking – the perfect piece to pop under a shell when you’re working hard in the mountains. It also works well as a ‘stash in the pack’ piece as it doesn’t take up much room.

What is it made of?

The Aconcagua uses Pontetorto Technostretch, a super lightweight, stretchy and breathable material made from a mixture of polyester, nylon and elastane. The polyester wicks sweat, the nylon adds durability and the elastane adds the all-important stretch that's required when climbing or mountaineering. 

What are the features?

Starting from the top, the Aconcagua features an under-helmet hood that sits snug to your head and features an elasticated border to keep the drafts out. The zippered chest pocket is a great place to stash your phone, compass or other bits you may need quick access to. The jacket also has comfortable stretchy thumb loops for a bit of extra warmth and comfort – these really come into their element under gloves as they ensure your sleeves don’t ride up when you need that protection. The Aconcagua also has flatlock seams throughout the jacket so you don’t get any chafing when it’s worn under a pack or harness.

How does it fit?

The Aconcagua fits into Mammut’s ‘Athletic Fit’ fit block; this means that Mammut have cut the jacket to follow the contours of your body whilst the pre-shaped sleeves, underarm gusset and stretchy materials ensure that you’re not restricted in any way.

Where does it fit in the layering system?

The Aconcagua is primarily designed as a Midlayer – this means that it works well as a layer underneath a shell or insulating jacket. However, it is not limited to that, the Aconcagua also works well as a stand-alone jacket on crisp, still, dry days or just as a round the town jacket.
