The 3D printed outers look cheap compared to the older version fabric support but, I believe it helps reduce weight and keeps everything connected with fewer pieces and therefore fewer failure points.
I’ve seen several reviews that say the printed version looks ugly, but I’m cool with it. I don’t dig the big Columbia logo printed on the side, but that’s not a huge deal. The color options are the Steel, Bright Green and the Black, Rocket. I don’t think either look too bad – especially when caked with mud!
One design issue that I don’t think is an upgrade for the IV model is the speed lacing system. It’s a bungee cord with a quick adjuster. The stretch in the lace isn’t something I want. I’ll be swapping out the stretchable laces for something static so I can keep the same adjustment throughout my runs.
