I ordered the Mountain Equipment Lightline Down Jacket after weighing options from all of the top brands. I read reviews, studied the specs and chose this piece because I felt confident it would handle anything Old Man Winter could throw at it. I was right. This jacket provides superior warmth in a relatively lightweight package with serious attention to detail. The hood is one of the best on the market. It's deep, adjustable and provides maximum wind protection. The pockets are deep, well placed and lined for warmth. The shell, while sturdy and well made is not as strong as I would like (be careful of sharp objects on the trail or slopes), but you have to admire the construction and quality of the materials inside and out. Adhering to the Down Codex, the feathers are ethically sourced and the jacket is stitched in such a way that they stay in place. The cuffs could use additional elastic, but the adjustable tabs make up for the slight lack of snap around the wrist. The fit is true, it hits right between the waist and hip, but is cut for a more athletic build. If you've got a gut, or large waist, order up a size for sure. I'm 5' 10" with a 43 inch chest and 33 inch waist, and a medium fits perfectly. This jacket is for serious cold. Start wearing it over a light base layer after the temps drop into the teens, and feel confident it will handle -20 degree f wind chill with no problem. I mentioned earlier to be careful with the shell around sharp objects. Let me explain: I took a slide on black ice and a piece of rock salt tore a 3/4 inch gash in the back. I wore it for two days before I found the tear and did not loose a single feather. I reached out to Back Country to see if they could recommend a repair methodology, and my Gearhead Matt P. had one suggestion: send it back - no questions asked - and he shipped the replacement the same day. Ask Amazon to do that for ya! love the site, the people and the products.
