In reply to drsdave:
Just went through the shopping process. Eventually got a Metolius Boss Hogg, used it and got it dirty and then saw a DMM Highball in Nevisport Kendal.
Boss Hogg appears good, but upon having a good look at the foam, it appears to be lower quality than what is in the DMM Highball. Also when it is open, the flaps and a fair amount of velcro on the Boss Hogg are in the dirt, so within one use the velcro is choked up with grass and dirt and I'm now of the opinion that what looks like a cool closure system is a pain in the arse.
Wish I'd got the Highball, still got flaps for closure and keeping things inside for walk ins, but not velcro based and looks simpler. Pretty sure the foam is far, far better too.
I also have an older, smaller Alpkit mat (a Phud maybe?) that I got for £40 a few years back when they were being sold off. That has some of the best foam and it is still as good as new now, I'm expecting the Metolius to be soft-as within a year...
I also considered a Snap Bun and one of the Moon pads. No regrets passing up on them, although my mates Snap is nice, appears to be pretty good foam.
Saw some Metolius Recons down at Dumby at the weekend, they do look pretty sweet. Maybe it's pot luck what foam the imported brands get filled with by distributors when they arrive here (I believe they just import the outers which would make a lot of sense). Vs DMM and Alpkit knowing what they are putting in them.
Hopefully of some use to you!
