I have had the apex for a bit it is a really cool piece but the front pocket bothered me and didn’t think it was comfortable with the elbow pads in.
The kiln is a good thickness and very comfy (tried on but never owned).
last week I was at the Kuiu showroom and messed with the hybrid 260. I will be ordering one of those in the near future to fulfill the piece that it appears you are looking for. Recommend checking one of those out as well. It should be a bit cheaper too.
Decision may come down to if you want merino or not. First lite stuff is solid IMO, I just really like the front pass through pocket on the kuiu personally.
