I’ve got quite the collection of midlayers these days but it’s my Mammut ones that get the most love from me.
My most recent midlayer purchase from Mammut’s range was the women’s Aenergy Light Hooded midlayer.
No products found.
Now, after 7 months of wear I’ve just ordered it in another colour.
Let’s talk pros and cons.
Mammut Aenergy Hooded Midlayer Pros and Cons
Pros
- Incredibly lightweight and breathable
- Very portable. Can fit in a pocket when not worn
- Hood can easily go under a helmet
- Super warmth despite being so light
- Handy front pocket
Cons
- No thumb loops in the sleeve!
Honestly, I fundamentally LOVE this midlayer.
To be clear:
- I bought it myself (and paid for it – this isn’t gifted or anything like that)
- I’ve worn it 7 months now regularly
- I’ve worn it on warm days as my top layer
- I’ve worn on cold days as one of a couple of “mid layers”
The Hood
This is a real highlight for me. It has a close fitting hood that can very, very easily go beneath a helmet if you’re climbing or cycling. Equally it can go under an insulated jacket hood.
I’ve always much preferred these tight fitting hoods on hiking midlayers. But the issue is generally that long hair gets sort of scrunched up inside them. So I was delighted to find this has the slot for extra hair š
You can also keep the hood down and still have this zipped up to the top with no discomfort.
As you can see at the front here, there is one quick access pocket.
It has a soft shell type fabric at the front too so you can probably keep something dry in there in light rain (wouldn’t recommend electronics mind as I don’t think it would withstand lots of rain).
Fabric and Warmth
Like lots of really decent quality midlayers, this one uses an almost repetitive square pattern like this on the inside:
I have a Mountain Equipment midlayer that is similar in having small squares of a fleece type fabric laid out like this.
Now, midlayers have to provide some insulation. But at the same time they are, in colder weather at least, underneath other layers. So it’s important they are breathable to allow moisture to escape your skin and get to your outer layers.
This one is incredibly breathable but also warm enough that in mild conditions I don’t wear anything else over much of the time unless it unless it’s raining.
Portability
When I said this can fit in a pocket, I meant it.
I fold it up into its own hood and either put it in the side pocket of my Osprey backpack or my Rab Cirrus Alpine jacket pocket.
It fits easily and then I can keep it in easier reach, particularly when hiking mountains, so can access it when it starts to get colder.
I Wish it Had Thumb Loops
I do miss the thumb loops that I have on my slightly thicker alternative Mammut midlayer and on many other of my non Mammut midlayers. Is it a deal breaker for me?
Well, no. But certainly if I’m multi layering in colder months, thumb loops really are useful to stop sleeves riding up. So I’d love to see them on this.
Would I Recommend this Midlayer?
All in all, yes. Absolutely. Breathable, portable and incredibly comfortable. Another solid product from Mammut.
