Nano-Air Insulated Vest

Enjoy uninterrupted comfort from the trailhead to the summit and back with the Patagonia Men's Nano-Air Insulated Vest. The ultimate in breathable warmth, this featherweight vest ensures that you won't be constantly juggling through different layers during early morning ski tours, chilly fall climbing sessions, or brisk afternoons around town.

The soft but durable outer fabric shields you from wind and light precipitation, and stays breathable so you don't get bogged down with sweat when the sun pokes its head out. It's built with mechanical stretch for unencumbered mobility when the going gets tough, and low-profile FullRange insulation to give you the right touch of warmth without adding bulk or restricting your movement. The slim fit allows you to comfortably layer this vest under a shell when touring, mountaineering, or ripping hard days at the resort.

  • Breathable insulated vest for warmth up and down the mountain
  • Stretchy shell offers unrestricted mobility for technical ascents
  • FullRange insulation keeps you comfortably warm during any pursuit
  • DWR finish repels light snow on high peaks
  • Low-bulk welted pockets wear comfortably with pack or harness
  • Stretch arm bindings and adjustable hem seal out elements

I bought one of these vests on November 21st 2017, and used it on a Christmas trip I just returned from. I only wore the vest on the plane and in Heathrow Airport, and was shocked to see the amount of pilling on both the left and right sides, from where the straps of my small day pack were in contact with the vest. I emailed Patagonia customer service one week ago and still have not received a response. As a loyal Patagonia customer for 18 years, I have used almost their entire product range, and have had very few issues except for the handles on a couple of the suitcases sticking and requiring replacement. Therefore, I was shocked to see all that pilling on the Nano Air Vest.I have over a dozen insulated or fleece Patagonia jackets and vests, and none have had this issue.

Picked this up along with the Nano Air Hybrid Light. Fantastic vest for nearly all 3 seasons. Excellent stretch and warmth without hardly any weight. Love this piece. You can check out this vest compared to the Nano Air Hybrid Light here youtu.be/3D2YbGw0dYA
