The best jacket out there for extreme cold winters

7 months ago

I live in Yellowknife with constant -30c average temperatures and this jacket is my security blanket!!! The length is perfect for keeping in the warmth and protecting the wind, while keeping my bum cozy. I truly appreciate the lightweight for when I’m walking with the dogs or shoveling. I constantly rave about how this jacket is my best purchase of 2024!

Crazy Awesome Jacket!

7 months ago

I've owned many many jackets, and this is hands down one of the best jackets I have ever had in my closet to throw on for walks, errands, and just general to-and-fro outings. I am impressed with the water-repellency and durability of the arato 30 nylon shell, the high neck and very sizeable hood, the warmth-to-weight ratio, doesn't inhibit a full-stride walk, and the color is gorgeous. A couple of other things to note about that jacket that I think are well thought out are the wrist gaskets (soft and trap warm air in), the double zipper (would appreciate a longer pull tab on the bottom zipper), and the packets because you could pretty much fit your life into both with how deep they are! Mary Poppin Pockets! I debated for a while on which brand I wanted to go with for a new parka, and between the perceived fit of the jacket while looking online, and reading about the construction, I knew this jacket would far outshine most others on the market. I expect to have this jacket for a very long time!

Totally worth it!

8 months ago

My far best investment I made. Worth every penny. Light, warm, also something to last. Definitely recommend. I've taken size M but realised S (170cm high, 62 kg weight) would be much better. It's perfect!

Great fit & super cozy, but watch out for wind.

8 months ago

I love a lot of things about this coat: tailored cut, excellent comfort, light weight, close fitting hood. It's plenty warm on a 20-degree day, even a 10-degree day...as long as there's zero wind. I wish the coat were lined, because a surprising amount of bitter cold wind creeps through those many seams. I really dislike the blank look of the GORE-TEX long coats, but need more wind protection than this puffer provides here on Lake Michigan outside Chicago. I'll still wear and enjoy this coat on many days, but it's not quite the dog-walking powerhouse I was hoping for!

In Love with this jacket

10 months ago

I have wanted to get a long length puffy jacket for years and kept putting it off until I found one that I really liked and this is that jacket. I am 5'7 and lean; I got a Small and the jacket fits perfectly coming down to about mid-calf with plenty of room to layer. The cuffs were unexpected - there is an elastic/stretchy inner that really blocks out any wind coming through. If you love pockets, you'll be happy to know there are 2 deep hand pockets that are lined. A chest pocket that easily fits my phone and more, there are also 2 deep "dump" pockets on the inside. The two-way zipper allows more airflow if you want. The hood is actually a decent size, not too large. Its SO warm and Cozy, just love it. Can say I am actually looking forward to the winter so I can live in this.

Lightweight basic for the winter!

8 months ago

I was looking for a lightweight/packable parka that would protect my legs in the cold and this is almost perfect. Pros are that it is lightweight, very comfortable and not at all bulky like many long parkas. It is great for cold weather, however it is not the warmest on windy days - on these days, I would still need to wear reasonably warm clothes underneath. In terms of fit, I'm 5'7" with a 27" waist and usually wear a small. I always end up having to purchase mediums in jackets because of my long arms. I bought a medium and I'm glad I did so I can layer underneath. The arms fit snug, but the body is a bit on the looser side. I wish it hugged the body just a bit more but I'm okay with a looser-fitting parka. Overall, it's a great purchase and I do plan on keeping it. I recommend snagging it when on sale!

Winter Perfection

3 months ago

This parka is exactly what I wanted for a move to Minnesota this year. It feels like it will regulate my temperature well for dog walks and has left me room to put on any extra layers I need. Arc'teryx products are always so high quality, and this is no exception. I'll be more excited for winter now - the sleeves and length are great for me as a tall person.

Light and warm

Super light and warm. Lots of room to layer under. I'm usually between a Medium and a Large and the Medium fit perfectly.
