  • 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 darned.

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 darned if my ultralight dirtbag skepticism hasn't been seriously challenged again.

brilliant jacket! needs one more evolution

this jacket is amazing! it looks and feels great, and as designed it’s temperature range is 65 down to 45 (easily). there’s no breathability issue either. the only problem is the sleeves (cuffs): the idea is great but the implementation is too bulky (there’re better ways to seal against heat loss than the heavy knit cuffs). as designed the cuff inserts destroy the natural line of the sleeve, and it’s a pain checking your watch. i’d recommend a light elastic cuff like the Ibex climawool line: zero bulk but traps air. still, make no mistake. this is a terrific piece and i’ll be wearing the **** out of it with real pleasure.

Beautiful jacket

I bought the Vertigo because it looks beautiful, and I had been eyeing the Alpha Snap for a couple years. My hope was that it could replace the merino hoodies from Kitsbow that I wear for my ~30 minute bicycle commute in Boston. I live in those Kitsbow hoodies and love them, but they are a bit casual for arriving at my workplace. So far, the weather has been too warm (> 50F degrees) for the Vertigo to function effectively for me on the bike. At these temps, I get clammy after about five minutes with the Vertigo. (SS merino base layer underneath.) I don't sweat easily or sweat much, making this noteworthy. I hope the Vertigo will excel when the temperature drops into the 30Fs and 40Fs. Until then, this garment will be mostly an off the bike piece for me. Because of this experience, I reread the reviews and I was surprised that breathability is touted. New England is more humid than other parts of the US, so perhaps the Vertigo breathes just fine in the desert or at lower temps. From a sizing perspective, I find the Large to be a little short and a little tight in the shoulders, but it is the best size for me (6'4" and 185lbs) since the XL seems to get wider more than it gets longer.

Kitsbow do it again

Have the original jacket- wear it everywhere. The Mk II is the same quality- even better fit. Can’t go wrong with this Jacket ✅✅✅

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.
