A comeback from the way back! We've had many requests to bring back this super vest, named after one of Oiselle's early designers (aka "Katron Bomb"). It's a fave for a lot of reasons! But of course, we can't simply repeat the past, we make it better. The updated Katron Vest keeps what folks loved: lightweight insulation from Primaloft®, loads of pockets, and streetwear style, and then brought in the 'new and improved' including Polartec® PowerStretch Pro as an ultra soft neck liner, and on the sides for ease of movement. We love the two chest pockets with hidden zippers, the side zip pockets, and of course, a large rear pocket for stashing extra goodies, snacks, masks, or sports programs. This is the go anywhere, do anything, stash and carry fall-winter vest you'll keep for a decade or more. Like Katron, a style icon!

Size down, beautiful color

After reading reviews I’m glad I sized down. I am 5’7”, 160lbs, 34DD, athletic/curvy build. I am normally a size 6-8 in Oiselle tops. Ordered a Small and it fits perfectly. Fitted, but not too tight. Plenty of room in the armholes and shoulders. I’m wearing a long sleeve pullover and a T-shirt underneath in the photo. There is some stretch in the side panels. The color is gorgeous deep green; it’s not teal, more like a pine green. Very warm. Can’t wait to try it out on a run.

Size down

I wish I’d listened to reviewers who recommend to size down. I’m an athletic 5’8” 135 pounds with 33 inch bust and 28 inch waist. The small is boxy and loose on me.

The color, fabric, pockets and zippers are all top notch. I really love the back pocket for storing hat, gloves while running. I always start out cold and need those layers. It’s nice to have a spot to tuck them away after I warm up.

Love the updates, pet approved!

I have two of the old Katron vests and they have been well loved and abused! Treated myself to the updated version and happy I did! The Douglas Fir color is amazing, the vest has 7 pockets!! and fits like a dream. I'm a big fan of the stowaway pocket in the back. I've been wearing it constantly since I got it but when I left it on the couch the other day, my dog took it for a snuggle nap test run.......she gave it 5 stars too. =)
I'm pretty steadily a medium and though the small fit, the medium is my happy place. Room to layer but doesn't feel too big.

Two tries to get sizing right but then perfect

Got this in medium, my normal size. Way too big in chest and upper stomach area. Knew I'd risk shortness in the torso and maybe tight armpits or shoulders with size small, but went for the small. It's actually perfect. It's fitted and sexy and super warm with its close fit. (Some looser winter clothes let too much cold air in.) I kind of feel and look like a superhero in this. Love it!
