Light, Warm, Packs Well, and Extra Coverage!
This was my main insulation piece on a fall hike of VT's Long Trail. It was light, warm and packs down well. The hood was nice to have and I loved that it was a little longer in back. Durability seems good. Temps went down into the 30s and it was fine with a single long sleeve wool layer underneath. Good piece of gear.
Excellent puffy jacket in many ways!
This jacket has been excellent so far. I have an REI 650 down puffy and this 850 down puffy picks up where its abilities stop delivering. It's a very comfortable jacket that fits snug, but not too tight like athletic fit, and it delivers down to 20° with a merino wool base layer. The stuffed hood, lacking on the 650 puffy, makes a huge difference. It has a grosgrain clip on the back. Tighting it, it snugs the hood around your head/face from within. I'm 6' tall and weigh approximately 190/200 lbs. An XL is a perfect fit for me. To top it off, I made an impulse buy when it was at a 50% discount. I'm totally pleased at that, but I still would've been happy if I paid full price.
Almost perfect with 1 big flaw
This is a fantastic jacket for the price. Kept me very warm in 2 degree weather and the water repellent works nicely. Good quality material and zippers work great. Fitment is mostly good but the big flaw is the way the zipper is sewn. When you stand up straight it creates a awkward bulge and looks like you are hiding something under your jacket lol. I was going to try to return it assuming that was a fluke but I have read other reviews saying the same thing so I am guessing this is why it was so heavily discounted when I bought it.
Awesome jacket but lacking in durability
Love this jacket! It is super lightweight, cozy, and comfortable. Great fit for all around use in cold weather. I am 6', 200lbs and the Large fits me perfect. My only complaint is that it is a bit lacking in durability. Less than 6 months in, there are already a couple of small spots where the down is coming out. I can repair it with tape but the down jackets I've owned from other companies have all had better durability. Definitely a bit disappointed in this one on that front, so knocking off a couple stars. Probably wouldn't buy it again. If you are really gentle with your gear, it could be great for you.
Needs tighter cuffs
Great jacket with one exception - the cuffs are much to loose. The jacket's material and fit are extremely comfortable. 5'11", 195lbs, 45" chest and the large fits great. Living in Florida now, I'm not very cold tolerant anymore - I get cold easily but am comfortable in low 30's temps with just a tee-shirt on under it. If the cuffs snugged up it would be a solid 5.
Overall nice
Nice coat - good look and feel, three zipper pockets, lightweight yet warm - although seems to form micro-tears relatively easily, early after my purchase. Hope the occasional insulation leakage I witnessed doesn't worsen. Bought some Tenacious Tape just in case.
Warm in 0° F!
Wearing a Smart Wool base layer under and a REI Drypoint GTX shell over, and I was warm in 0° F (-9° F windchill) weather in Wisconsin! Just walking with this set-up for 10 minutes and I had to open everything up and vent myself as I was already starting to overheat under. I bought a size L and am 5’9” and 215 lbs at the moment, and the fit is really good. I only have 1 gripe, and it is that the cuffs suck. They have elastic on them, but it does nothing really. I could fix it myself if I really wanted to, and may do so later on. I love this coat though!
The perfect down jacket
Purchased this coat as this was my first year of hiking the SHT in the cold weather here in Minnesota. I love it! It’s super light at under 14 oz and extremely warm even though it fits slightly loose but is good for layering or your backpack while hiking! It’s like the perfect down jacket all rolled into this one product for a much cheaper price than the competitors like Patagonia or The North Face. Plus very stylish! I highly recommend it!
Best bargain for this weight/warmth
Fantastic jacket for the price, especially when it goes on sale or with a code. The cut is slim enough to keep excess air out, but I was able to add two base layers underneath with no problem. The hood is cut well and stays put. Sleeves are the proper length for me. The baffles are uniform and well filled for this mid-warmth jacket. The only things I would change is to add an inside pocket and have more horizontal room in the hand warmer pockets. Without gloves, my wrists are not covered in the pockets. For reference I am 6', 185lbs and narrow shoulders.
By far the best down-filled jacket of all.
The 850 weight is toasty warm and very light. Not at all bulky or heavy. Similar to the 650 but the sections are a little smaller and the coat is lighter. When shopping for coats like this, don’t be fooled only by the weight number - that’s not the total indication of overall warmth... a higher number just tells you, in effect, that it takes less of the down to produce the same warmth level (eg the coat will feel just as warm but with a lighter weight). I don’t prefer a bulky coat so this one is perfect for me. Also be aware that this is not going to work without a shell if you are in a wet weather situation. It will not keep you warm if it’s wet. I use this under an Arcteryx Beta Jacket, but there is an REI waterproof shell that is just as good and probably is cut a bit better to fit the down jacket. I would definitely recommend this product as better than competing offerings from Patagonia, Arcteryx, and others that are similar but sold at a higher price or priced the same but inferior in terms of weight.
