Good shout Brian, going to try that as I am hoping to do a tour in France this year and not sure my backside will endure the daily riding that well!
I just took my own advice Dave and ordered a pair of these...http://www.amazon.co.uk/exec/obidos/..._ya_os_product
....I'll let you know how I get on
Reading the recommendations/reviews the opinion is order the 'next size up' as the fitting is tight. I'm a 32'' waist...so I ordered the 'large'
