Fortunately for fans of high-quality clothes at pretty unbelievable prices, Everlane has been busy this season. They're building out their wardrobe this winter: $100 cashmere, a new and highly anticipated denim line, ankle boots, and now the "big white whale" of winter ensembles — the flattering, but completely functional puffer coat.

They've rolled out a bunch of cuts to suit your lifestyle and needs, but you won't find anything over $198 despite the fact that every puffer coat uses military-approved PrimaLoft down for serious warmth. Despite their impressive cold-weather capabilities, all of them manage the same slim and of-the-moment silhouette.

They've also included a Unisex Parka closer to $200, which is the warmest coat in the collection.

PrimaLoft is an alternative down developed for the US military, with superior warmth and water resistance being the highlights of its resumé. It's lightweight, breathable, and machine washable, too.

Part of keeping Everlane's costs low is a lean production cycle, and they've certainly been on the rise for demand. If you want one of their puffers before they run out, a good strategy is that sooner is better.

Check out all the cold weather options below:

The Unisex Winter Parka

For the very coldest days, Everlane has the unisex Winter Parka. It has hidden talents like a drawcord at the hood and hidden wrist cuffs to keep the chill out.

The Hooded Puffer

The second-warmest puffer in the new collection, the Hooded Puffer has a snap-on hood to lock in heat and is best prepared for 15-30 degree days.

The Lightweight Puffer

Thanks to that military-approved PrimaLoft, this puffer delivers a level of warmth disproportionate to its light weight and lack of bulk. It's best used for 30-40 degrees and layering.
