Thank you, Gustavo! A 10 out of 10 for the winter jacket is great to read.
Love the coat, quite happy with it. I have asked a few times on how much the fill weighs, how many grams or ounces. They never say. Tell me it’s 1000fp and they can get me the weight of the fill but they never do. Disappointed with their customer service.
Store owner replied:
Thank you, Szabolcs! Glad the T-shirt is to your liking. Enjoy it out in the field.
Jakość Waszych produktów jest rewelacyjna - z pełnym przekonaniem kupuję tę odzież dla męża i syna, którzy bardzo ją sobie chwalą. Jako polująca Diana ogromnie żałuję jednak, że w stałej ofercie brakuje dedykowanej kolekcji damskiej. Z przyjemnością wyposażyłabym również swoją szafę w tak świetną termoaktywność. Bardzo proszę o pomyślenie o nas, kobietach w kniei!
The quality of your products is sensational - with full conviction I buy this clothing for my husband and son, who praise it very much. However, as a hunting Diana, I deeply regret that a dedicated women's collection is missing from your permanent offer. I would gladly equip my wardrobe with such great thermal activity as well. Please consider us, women in the knie!

I am very satisfied with the product and transaction. Recommend this.
The jacket is surprisingly lightweight and very comfortable to wear. I always take it with me when I travel. Warm and light.
Review from www.hillmandeutschland.de
It was fantastic, feather-light, and could be stored in the smallest space. It will always be with me.
I'm a veterinarian, and the weather can change quickly.
Review from www.hillmandeutschland.de
The down jacket is excellent – warm, packs down small, and is wonderfully comfortable to wear. Exchanging it for a larger size was hassle-free and free of charge, including pickup by the courier service!
Review from www.hillmandeutschland.de
