D30 Back Armor Vent Holes

[Grumpy Goat]

If you look at a new D30 back armor you'll see most of the vent holes are blocked by a very thin skin.
The ribs of the back pad should give you some air flow but I like to open the holes using a small solder iron.

There's a little discount on the 2018 Klim Induction Jackets now and I bought one from Motorcycle Gear

That looks like a big improvement on the airflow. I have no idea why they would not open up the holes like you did. It is not as if doing so will reduce the impact resistance.

I do like the price and the design is OK (although I prefer the new design). The issue I have is the fact that it does not even come with a rain layer. I guess I have been spoiled by my Olympia jacket which is a proper 3 season jacket including over/under rain liner. Other than that I love my [waterproof] Klim gear.
