  • Our update on our very popular insulated jacket. Among the improvements are the front snap placket and the rib knit cuff; both redesigned to better keep out the chill. If you liked the original Alpha Snap Jacket, you'll love our updated version.

The Vertigo Jacket

The key to this piece is the fabric. This fabric was developed for use by U.S. Special Forces with a simple objective: eliminate the need of adding or dropping layers during dynamic and static activities.

The fabric technology also allows for the transport of moisture without getting cold; so, unlike your puffy down jacket, this jacket will keep you warm when moisture is involved... or inevitable. 

For this version, we gave the exterior a C6 DWR water resistant treatment. This allows water to bead up and keeps the surface of the piece from becoming saturated with moisture.


Fabrication & Features

  • Hydrophobic insulation on front of torso for fast-forward activities with lighter fill on the back and in the sleeves
  • Two-way structural blend, 97% nylon exterior for abrasion resistance,100% polyester interior optimized for wicking and mechanical stretch
  • Certified to meet air permeability standards
  • Brushed fleece lined pockets 
  • UPDATED: Snug-fit ribbed cuff for better insulation and fit
  • Schoeller 3X Dry Paneling on the elbow and forearm for greater strength in the high use regions
  • Kitsbow secured stash pocket, reflective back hem


"A nice, classically-styled shirt jacket that’s as technical as it gets thanks to Polartec’s new Alpha insulation that’s capable of handling large variances in ambient temperature or body heat, so you can wear this single item from a chilly afternoon to a frigid night and simply be comfortable the whole while.

"The lightweight nature of this jacket makes it feel great on, but don’t let that fool you into thinking this is only for warmer weather. Its polartec interior is designed to handle the drastic temperature changes of the fall and its tailored fit will have you looking good on the bike trails or strolling through the city."

"I’ve actually ridden a mountain bike in this midweight on a cold morning in November, but the Snap Jacket is more of a café cruiser item: It’s technical, but casual. The Polartech Alpha breathable insulation keeps you warm without overheating. The jacket/shirt styling means I wear it-probably too much. "

I'll be ******.

I've waited a bit to write this. I'll admit, at first I was skeptical. After years spent in visibly high tech down puffy jackets, I was skeptical of a lower full, synthetic jacket. I was wrong. When I first got it, I thought it would be too bulky to replace my UL down, especially because it might not be as warm. To some degree, this is still a bit true. The difference is, I dont find a reason to take my UL puffy with me everywhere. It's too hot, and frankly I'm not a fan of looking like I should be at base camp when I'm at the brewery. I've worn this garment nearly every day since owing it. From cold nights in Arizona, to beach camping in Baja, and plenty of places where I wanted to look good and be warm as well, this hasn't left my pack or my back. Is it a total replacement for ultralight missions? Maybe not. But it is probably the most versatile piece of clothing I own, blending function and form perfectly. And honestly, for summer bikepacking, it probably will replace my big puffy anyway, especially considering it resists tearing far better than my other Puffys. This is the most pleasantly surprised and impressed I've been with a piece of clothing, and I'll be ****** if my ultralight dirtbag skepticism hasn't been seriously challenged again.

Simply Amazing

I really like this updated version. It feels more durable with the new outer-shell and the fit is looks better making it a staple for the bike trail to a casual outing. The updated new pockets are perfect, especially the one on the back. Overall, very happy with this purchase and it'll probably be my go to jacket for everything. The only minor issue I have is that it doesn't quite have the stretch as the previous one.

This is the kind of wardrobe piece that when you see it you ask yourself “what would I use that for?” But once u own it, if you find you can’t live without it. My husband lost his and could think of little else until he knew another one would be coming under the Christmas tree. There are two classes of down shirt- style jackets on the market: expensive and not so expensive. In case you were wondering what the difference is, it’s durability. The less expensive brands do not have the Same quality outer fabric. They are easily torn and down leaks out more readily. I can’t say that we are fans of the recent modifications. We preferred the prior styling, without the contrast fabric on the lower arms. But even with that, and the higher price point, it’s my husband’s favorite down shirt on the market.

Best Jacket/Shirt....Ever

The new Alpha Jacket is my go too alone over t shirt or as a full on jacket. New sleeves keep warmth in and still hidden so it looks like a typical shirt sleeve. Kitsbow makes the highest quality products period.

The jacket that fits in anywhere

I've never had a garment that fits into more spaces and does so with style. From the trailhead to date night I literally wear this thing everywhere. The fit is perfect for an lean active body, slender waist and long slim sleeves but still gives you room to layer. You also can't beat the fact that every time I wear this jacket someone compliments me or asks where I got it.
