I got both of my 12x5 pouches from Fenix Torches (the UK site) but they currently don't have the Khaki one in stock so it looks like the other suggestions may be a better bet right now
I got everything today
except for a Zebra billy can (the store was completely out of stock). Too late to get them in time for Friday, so I'll just empty the contents into my canteen cup and heat it up the old-fashioned way. Cooks just the same, so no big deal for now
Got a lovely reel of DMM 11mm static climbing rope, too! About to string up the hammock and thread it through to replace the crappy webbing loops. I'll be doubling up the tree huggers for Friday as well (just in case the weather decides to kill another one) and the self-inflating matress should make the same degree of difference that Paul's did on Saturday (kept my **** warm... and that's what matters!)
I've also decided to pitch two tarps on Friday (one inside the other with a gap between). I want to see if it provides sufficient insulation and allows me to keep the tarp from blowing in against the hammock and sapping out heat like on Saturday. That said, it all comes down to the trees! If there are the right trees in the right places, I can string the hammock further away from the tarp sides and that'll work great too!
Anyway, proof of the pudding is in the tasting, so there's no point in me theorizing what difference these modifications will make.... I just have to test them out!
