I was in TKmaxx Paisley and they had a good selection of gear4 ipod accessories. My son was going to buy a silicon skin for £5.99 when he noticed this.
You get two skins one black one white plus a screen protector plus two straps. It is specifically marked as 2nd generation so is a good fit for the newer touch. I don't know if one of the straps is meant to be an extension for larger arms but fitted round the wrist and one fitted round the bicep. I have had a look on the web and the cheapest I saw the twin pack for was £9.97 at Tesco.
EDIT thanks to Chris uk HMV are selling these at £5 listed online doesn't say twin pack or 2nd gen but same product code.
