I just want a bit more room as the hunka is a tad slim for larger lads
Hunka 'Rotund' is good because....
It's bigger, it makes a big difference over a standard Hunka
(I fit in, I have my mat on the inside, I can keep a lot of my stuff in with me and there is still plenty of wriggle room)
It's cheap
(well it is)
It's very waterproof
(I turned mine inside out and filled it with a hose pipe to test, it was very heavy but didn't leak)
Downsides....
Slug attack! (it lacks a mosi / insect net type affair)
A touch bulky, but you have to be splitting hairs and if you want a bigger bag it will be erm... bigger
In the real heavy rain of the WRT it didn't breathe 100% but I think the rain on the outside would have buggered any 'breathable' fabric
I like mine and feel no real need to change / upgraded it (although I may alter it using velco and a mosi net)
