This 2nd generation Oros jacket (bought December 2017) is far superior to the 1st (Lukla)! I was disappointed with the first one because it fell short for Arctic application. This new one, I love it for the following reasons:
- This new one is 100% insulated with Aerogel Solarcore, while the first one was NOT resulted to significant cold-spots (no Solarcore in inside arms, upper back, shoulders, hood) in Arctic climate. While the previous one needed extra thick layers due cold-spots in below zero temperatures, this one all you need is thin dry-fast base layer. It is ideal for active sport in very cold activities.
- Truly three season jacket! Since Aerogel is poor thermal conductor, the Solarcore insulation remains at constant temperature whether outside blazing hot or liquid Nitrogen cold. I wore yesterday when it was rainy 65 degrees Fahrenheit. This is the same jacket you bring to rainy mild Seattle and brutal cold North Pole to see Santa!
- Really thin profile. It feels and looks like a regular non-insulated shell.
- It is lighter due to slimmer cut, smaller hood (climber helmet won’t fit?), and no more powder skirt.
- Great underarm zippers for ventilation.
- All zippers are self-closing with plastic tabs to prevent water and wind penetration.
- It has well integrated palm gloves.
- The outer shell feel strong, but it is not as thick as the previous one. For rock climbing or going through thick brushes, I will put an extra cheap nylon jacket to prevent rips. I hope the next generation will have reinforced elbow and lower arm patches.
- It is very well constructed, and looks conservatively stylish.
- Beware, it is slim fit cut designed for less layering!
- Many packets, but I think they should reduce them to further lighten it down.
