And more..

I never thought my video would generate this much interest! I'm going to continue to publish comments that deal with safety because it's important for people to look at these issues and make their own mind up. So, Martin Rye said:
Couple things and more. On a multi day route you would miss those spare clothes. Wet days on end would push the safety boundary in my view. You would be safer with spare warm clothing to get into in an emergency. Wet clothing wicks body heat away five times faster.

It seems that every time I've taken this kit out, it's been wet days on end so I've got a fair understanding of how it works. The cape/chaps combo does a good job of keeping me dry except for the ends of the arms-I've been just as wet in traditional waterproofs and I would always save my dry clothes for when I got to camp. But when I'm in camp, if I'm really soaking, I can take my wet clothes off and get into my sleeping bag and put on the down vest which will keep me warmer than a fleece or long johns and not getting into the sleeping bag. What I actually found myself doing was just wearing the clothes until they dried when I got to camp. I wear montane terra trousers and a smartwool microweight baselayer which I have found dry extremely quickly. on my feet I wore coolmax liner socks which also dry very quickly. I do run pretty warm though. I dried at night and got wet again during the day, which was similar to what I used to do which was wearing dry clothes at night and putting wet clothes on again the next day.

I like Caldera stoves but they can flare up and set fire to the ground. If your shelter burnt down what would be plan to keep the elements of you without a waterproof? Good luck to you but would it work on a five day no resupply wet Scottish route in May?
I haven't had any problem with my caldera setting fire to the ground, but if it's dry, I put it outside the tent. If it's wet, then there shouldn't be so much of a problem with the ground catching fire but should the worst come to the worst, then silnylon burns slowly. The worst should be a hole in my waterproofs. There's enough material in the cape to be able to bunch it and tie it off or even just wear it with a hole in it- I'd be generally covered. 5 days no resupply in a scottish May? I don't get the chance to get up to Scotland much unfortunately but my understanding is that I may well be encountering snow etc. I would be more likely to pack a kit that reflected the more wintery conditions and lower temperatures, but if it's cold enough to wear a micro fleece, that would be on my back and not in the pack. Wind is the real killer with the cape as a waterproof but only if you're going up high. The main change I'd make for a 5 dayer is spare socks- my socks reek after 3 days!
Also does that pack keep all the kit dry without stuff sacks? Yes!
