[This review was collected as part of a promotion.] Absolutely love this jacket, it's extremely light, yet still so very warm. The black color soaks up the sun during tough alpine days, and lets you regain the drive to keep getting after it! I've climbed about 50 rock pitches in the front range wearing it so far, and it's still held up fine with no rips or tears. Unfortunately I don't have any photos of it in massive action, but I do have some stylistic shots of my partner wearing it around during and after a boulder canyon dragging day. It was very very cold outside (plus, she's a tropical person) and she had no complaints! Mammut gave me this free product to try, and I received this product for free in exchange for my honest review. This doesn't diminish my viewpoint of the product though! I'd likely purchase it myself if I was not gifted it.
I picked one of these up this past spring and am finally getting to really put it to use. I run warm to begin with but, this jacket has been quite impressive so far, keeping me almost hot down to about 30F with just a t-shirt underneath and jeans. It is probably not going to replace my MHW thick puffer for deep winter but it is going to see some use for layering on my winter camping trips. It is incredibly light and compresses well but I really struggle to make it fit in the pocket so I generally just stuff it in a dry bag and squeeze the air out. I haven't tried any similar UL puffers but this one feels great compared to the entry level ones I've tried in the past.
I have not been able to "push the jacket to the limit" but the times I have worn it so far I am pleased! I think it is hard to find a better high fill down jacket at the price point (ExpertVoice price)! It is lightweight and compacts down to a pretty small package. I have not tested it when it has been wet but I suspect it will perform well in light rain conditions. The only thing I don't like is that lack of lined exterior pockets. Definitely not a deal breaker but would have been nice. I would recommend this down hooded jacket to anyone wanting a high quality ethical down jacket!
The jacket's zipper keeps coming undone, and I have to keep adjusting it. Additionally, the jacket I saw in the store in Gdańsk, Poland, had more down filling, especially on the sleeves. I thought the Mammut brand and high price meant quality. Unfortunately, I was disappointed.
