Kyanite Fleece Vest

Rely on the Arc'teryx Kyanite Fleece Vest to keep your core warm during high-output outdoor activities without slowing you down or holding you back from performing at your best. Layer it under a shell in harsher conditions or wear it as a standalone piece when the weather is more mild so you can use it for everything from climbing and hiking to backcountry skiing.

Polartec Power Stretch Pro fabric stretches effortlessly so you can reach the toughest holds and shred powder without restriction. The articulated patterning also aids in unrestricted mobility. A tough nylon face fabric withstands brushes with root and rock, while the soft brushed interior traps heat to offer warmth without the weight. The Kyanite wicks sweat to keep heat-robbing moisture from leaving you cold and clammy, and it also breathes exceptionally well to keep you from overheating during arduous ascents.

Larger interior pocket needed!

I've used it once or twice and have initial impressions
Runs small

I've been rocking Arc'Teryx Apparel and using their Gear for 21 years now. So I know the innovations that the Arc'Teryx Designers were known for, and I know the back-steps that they've taken regarding their loss of articulated apparel patterning. Arc'Teryx: Kyanite Vest Men's. Sizing/Fitment: Fitment is true to size! Not loose, slightly snug in the belly but it does stretch significantly. You don't want a mid-base layer to fit loose like a sweatshirt. I prefer the patterning and fitment of the awesome Men's Fortrez Hoody. Comfort: The comfort is good due to my favorite fabric Polartec Power Stretch which is even more Stretchier than before which is always a bonus! The patterning is pretty basic. But as always I do miss the old-school Arc'Teryx neck patterning that they were always known for. I would LOVE to see some Wrist Thumb Holes just like on the awesome LEAF Naga Hoody Gen 1 & LEAF Cold XZ Zip Neck SV, and especially on every mid-base layer, Arc’teryx makes. That's an important functional feature that needs to happen asap! Quality: Polartec Power Stretch has always been the number one fabric for me that Arc'teryx has utilized over the years in different weights, but I prefer the thicker weight because it lasts longer through usage and washes. Note: do NOT put in the dryer. So I totally LOVE the new Polartec Power Stretch that's even softer and stretchier than before! Polartec Power Stretch is utilized in my favorite pieces such as the: Rho AR Zip Neck Men's & Rho AR Bottoms, LEAF Naga Hoody Gen 1, LEAF Cold XZ Zip Neck SV, Fortrez Hoody Men's, Kyanite Hoody Men's. I don't care about weight. I care about proper fitment, overall comfort, stretch, warmth, styling, functionality, durability, longevity, and most importantly quality! I don't like the change to the main metal zipper pull, I much prefer the look and quality of the older YKK rounded Aluminum can pull-tab shaped metal zipper pull that was covered with a thick coat of paint which has never ever failed me. Request: Please go back to the older tried and true YKK rounded pull-tab shaped metal main zipper pull tab, larger interior pocket w/zipper. Medium Gray color-way. Pros: Fitment, soft and stretchy material (Polartec Power Stretch), usability, flatlock construction, new No Slip Zip concept. Cons: Flimsy new main metal zipper pull tab, no petite zipper garages, no exterior auxiliary pocket. Interior pocket w/zipper is too small for current iPhones with a slim case. The interior pocket and zipper need to be an inch taller and an inch wider, and the zipper needs to be at least an inch and a half longer. The interior pocket as of now you could only fit a small phone, or a Cliff Bar, or a key fob with lip balm. Arc'Teryx Designers need to anticipate future mobile smartphones sizes, which are increasingly getting larger. I also don't like having to un-zip my fleece to get an item, I much prefer an exterior chest pocket just like on the Men's Fortrez Hoody. No Medium Gray color-way. Arc'Teryx please bring back the awesome Gamma SV Vest! GearFreakNY :)
