So with design almost wrapped up, get in and put your mark down for the size and colour(s) you'd like. We need real commitment from you dirtbag climbers to actually buy when you do so...or poor Matt will be out there broker than a broke thing selling hisself to repay the production costs

No, my friends, not a pretty thought is it?
The colours are not exact but from feedback we will try to match up what you've said you want with what the printers can supply. Hence the colours listed are a bit ambiguous...work with us on that, OK? Size according to your regular comfy size. We will try and make sure they match up as well as we can....but it's hard to guarantee everyone will find the sizes exactly right.
It will be possible to have multiple colours....so not everyone will have the same colour Tee, but we will limit the options here to 4 or 5 colours - you can select more than one colour (but please don't select more than 1 size unless you are buying more than one Tee in different sizes!).
So go on, have a look and tick off what's good for you (and urge others to do likewise!).
