Review: Mammut Broad Peak Hooded Down Jacket

Written by Fiona

I have been testing the Mammut Broad Peak Hooded Down Jacket. It claims to be warm, lightweight and durable. Here are my thoughts.

But first, a few words from Swiss pro alpinist, Dani Arnold, who has been using the Broad Peak jacket recently. He says: “This jacket almost always comes with me. I don’t know how many bivouac nights I have spent in the jacket.”

Features include:

  • Good warmth to weight ratio
  • 800 fill down responsibly sourced down and feather filling
  • Fabric: Pertex Quantum, which is a tightly woven structure of fine yarns to provide a light and soft fabric and allowing the insulation inside to fully loft.
  • Pertex Y Fuse technology. Unique Y shaped yarn filaments create a tightly interlocking structure, which improves the downproof and water beading properties of the fabric.
  • DWR treated (durable water repellent) to shed light rain and snow
  • YKK Vision 2-way zip
  • One-hand adjusted drawstring
  • Elastic cuffs and hood edge
  • Chin protector for zip
  • Jacket packs into its own side pocket
  • Male and female designs
  • Weight: Women’s 330g; men’s weight: 380g
  • RRP £269 (currently £189 on the Mammut website)
  • Mammut

On test: Mammut Broad Peak Hooded Down Jacket

I was sent a size medium to try. It is a bit big for me but I was still able to review the jacket for warmth and quality.

The shape of the jacket is also quite square. I prefer a fitted jacket with a design to suit the female physique but I have not found the Mammut to be the most streamlined fit. It is good for adding extra layers underneath, however.

The jacket feels really lightweight; almost like it has been filled with air. It sort of floats around you, yet it’s still really nice and warm.

I have worn the jacket as a general kicking about jacket on chilly days and also on mountain tops when it has been properly cold and windy. Because the jacket is a bit big for me it fits over lots of layers.

I have found it is very good at keeping me warm and toasty.

I thought that the fabric did not look to be that durable because it is so light and silky but it has stayed in remarkably good condition. I have put it t the test by pushing past trees and through prickly bushes. It’s still looks good and has no obvious marks, tears or pulls.

Other features that I like include the two-way zip and the large zipped pockets. The pockets are useful for carrying bits and pieces and one also doubles as a place to stow a jacket when it is not being worn. It has a two-way zip so you can use it as a pocket and as a bag.

Mammut claims that the jacket packs down small. I don’t think it’s that small.

Packed jacket and a can of juice.

However, the jacket does offer a lot of warmth so I think the packed down size is okay. I just feel that Mammut is being a bit misleading when it states it packs down small.

The jacket is expensive at £269. In fact, Mammut are currently selling the jacket for £189 so perhaps they over-priced it at first.

I was sent the silver coloured jacket to test and while it looks smart it ends up getting dirty quite quickly. There are other colours and I would recommend buy a darker coloured jacket.

Overall the Mammut Broad Peak Hooded Down Jacket is a good quality jacket. It is lightweight, warm and seems to be made of durable and good quality materials. I just wish the shape was a little more flattering and I would prefer a cheaper price tag.

See Mammut.
