I have a low volume foot so the cable adjustment system works fine for me. I can tighten down the boots so I don't get heal lift, and when the front tightens down as well, it doesn't impact my narrow, low volume foot. My concern was whether they would work for winter mountaineering day trips in CO. So far I've been pleased and had warm feet on two separate trips. The first trip had air temps around 5F and a windchill of -35F. This was all above 12000ft so these boots work well for snow climbing and short approaches. I like the cable adjustment system since it doesn't loosen up over time like laces and you don't have to spend much time dialing in the fit, which is good when you're exposing your hands to subzero windchill.

This harness would not be a good harness for vertical caving with a Frog ascending system. The harness clip in point is way too high for your croll ascender, so you wouldn't be able to tighten it down and would spend most of your time hand feeding the rope through it.

It does look like a pretty good harness for canyoneering, especially for the price. Nothing worse than shredding your new harness in a sandstone slot canyon after a couple of trips!

I've had this helmet for a couple of years and it has never had any hits, but I cracked the shell in the back when it lightly hit something while hiking out from canyoneering. It was just clipped onto my pack and swung out and hit a tree branch or something. I would expect it to be a little more durable.
