Warmth to the core.

The Patagonia Men's Nano Puff Vest is the ideal insulator under a shell for skiing and snowboarding, and it can be worn by itself for running and hiking in cooler weather. The PrimaLoft One insulation keeps your core toasty on cold mornings on the trail and brisk nights in the resort. This lightweight vest is also highly compressible so you can stuff it virtually anywhere on trips without sacrificing space.

  • DWR-treated recycled polyester is ideal for skiing or snowboarding whether it's worn over midlayers on bluebird days or under a waterproof shell on stormy days
  • PrimaLoft One insulation keeps your core warm so you don't have to wear tons of extra layers
  • Compressible insulation and fabric so it's easy to bring along
  • Two side pockets prevent your hands from numbing up

Perfect for layering when Alpine Touring

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This is my "go to" layering piece for when I'm touring, mostly I use it as a mid-layer in warmer touring climates like Australia and NZ. Having a synthetic fill rather than down works much better in these warmer environments as it's not a problem if it gets a little wet.

I find the best use is when I'm skinning and you hit an exposed ridge line and it gets a little colder or you're suddenly in the shade for a while. I generally have it under some compression straps on the outside of my pack and it's easy to quickly take the pack off, chuck it on and move on quickly without opening and searching your pack for a shell.

It's super light and compresses into it's own inside pocket about the size of a really fat beer can.

great part of my layering system. pretty warm considering it feels like nothing. packs small and light. i wear it all the time when a jacket feels like it is too much.

Minimal feel, fits slightly small

  • Familiarity: I've used it several times
  • Fit: Runs small

Great minimal vest as part of a base layer system, used snow shoeing and cross-country skiing in mid teen temps in CO over Christmas. Fit runs a bit small.

Great versatile vest

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Living in the Pacific NW, the decision between down and synthetic is always tough - it can get wet around here. This vest has been great. It's pretty light weight, it stays warm when it gets wet, packs down into the pocket (and still squishes down more after that), is durable, and fits true. I take it on every trip in every season because it works with every layering combination.

light and warm

  • Familiarity: I've put it through the wringer
  • Fit: True to size

The Nano Puff vest is an awesome and super versatile piece. Packs down super small in it's own pocket so it's a good one to always have on ski tours and late season bike rides, and looks good enough to wear every day. For resort skiing it's a great piece to throw on over a fleece mid layer for super cold days, it gives me just the right amount of warmth without being too bulky or overheating me too much like a full Nano Jacket might. Revised this year with an updated (smaller brick) quilting pattern, less boxy fit, and an inch and a half extra length in the body.

Tested and Approved

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

I recently snuck this out of my brothers closet when I was going on a fall mountain bike ride in Park City, Utah. I tend to overheat easy, so I wanted just a little something extra in case it got cold.

Turns out, it started snowing on that ride. I'll be honest, this lightweight vest didn't keep me toasty, but I could feel the difference between my arms and chest. Although, I barely felt like I was wearing a vest, this thing is really that light.

Oh and when I got home I was covered in mud from my ride and a quick cycle in the washing machine was enough to clean this vest up without messing up the primaloft insulation.
