My thoughts: Mammut Crag IN jacket 

I would always prefer to choose a hooded jacket and even with the additional cost at £10, this is what I would buy. However, I was sent the non-hooded version to test so that is the jacket I will write about.

The jacket fits well and had a nice female-specific shape. I am not a huge fan of the flux colour but there are other options.

It feels like a mid-weight jacket, so it’s suitable as an outer layer on cold days in spring, summer and autumn and as a mid-layer, beneath a waterproof jacket or over the top of another warm layer.

The zip is one-way, which annoys me because I like the versatility of a two-way zip. There are also two zipped hand pockets.

While the jacket looks fairly ordinary overall, what stands out is the recycled content. Synthetic fill is great ofr keeping your warm when it’s damp or wet (compared to down, which can end up soggy and cold) and it has great eco-credentials because it is made with recycled scraps from industrial ropes. I like the re-use of materials that would otherwise be treated as waste.

The outer fabric is also made with recycled materials, plus the water repellent treatment is environmentally friendly PFC-free.

Of course, buying fewer products and purchasing second-hand where possible is the more eco-friendly thing to do but if you do need a new insulated jacket and you want a new product from a reputable brand, it’s good to buy items that are better for the planet, than making it worse.

The price is also very reasonable for a good quality insulated jacket. I like that there are three versions, too, hooded, standard and vest, and it a wide range of sizes, so the consumer has plenty of choice.
