Said insulation is sandwiched in thoughtfully arranged baffles stitched into an outer made from Pertex Quantum synthetic fabrics that shed water. More on Primaloft here, for the record, a 200-gram insulation rating is ideal for very low activity in chilly weather or moderate to high activity in frigid weather. That warmth comes thanks to a 205-gram PrimaLoft Thermoplume insulation. While not as packable as, say, a Patagonia Micro Puff, which rolls or folds down to the size of a grapefruit, while not as waterproof as Columbia OutDry Diamond Puffer, and not frankly as flexible and full-range-of-motion as some other packable coats, the Icarus is simply the warmest coat of its weight and size that I have yet found, and that’s saying a lot – I test a lot of coats, and way beyond the packable/puffer category.

That’s because the Icarus jacket is simply a great puffer. Whitney (multiple times), and many of Southern California’s 10k and 11k peaks.īut if I had to make a split-second choice when heading out the door into cold weather with specific conditions unknown, I’d grab my Montane Icarus Jacket every time. And others I keep because they work just fine and have sentimental value, such as one I’ve worn up Mt. Another has a cut that makes it look almost stylish – not any easy feat for a packable jacket. One is as reliably waterproof as any raincoat I’ve ever tested. I can justify the said seven or eight I’ve kept in myriad ways: a couple are ultra-packable, collapsing down so small they can tuck into the smallest pack or even into a pocket. I own seven or eight puffers right now, and over the past few years I’ve tested out at least a dozen more.

And it will still keep you warm even if it gets wet. I strongly recommend the Icarus Jacket from Montane because it is a midweight jacket that will keep you warmer than many parkas, yet will still pack down to fit into your daypack.
