I’ve had a Dryrobe (the waterproof one) for 3 or 4 years now. Great bit if kit. Dont leave home (when the weather is pants) without it.
I use it a lot for before and after open water swimming too. I’m pretty tall and its still ok for getting changed in – the arm holes / sleeves are well sized to allow you to get arms inside / outside without problem and without dislocating a shoulder.

I’ve not tried it as a portaloo however.

TBH I can’t see how you beat a totally standard doormat for standing on and changing.

for me it has to be a 40Litre tub in winter, fits muddy cloths shoes, helmet and bag,,

and a rubber matt

Oh my, how can I get hold of Dry Sure shoe dryers before I leave work??? NEED!

is that shoe bag a joke.. £39,

and the shoe dryer, i’ve always used newspaper balls scrunched into the toe since my days in the gelpac snappies sunday junior football league with my footy boots, an overnight under the radiator, next day take out the wet paper, (reapply is neccesary) but usually leave them for another day and they are dry.

“Jetboil and an aeorpress / supply of teabags / hot chocolate is worth packing if a cafe visit isn’t on the cards too.”

Or a thermos.

20 quid for a polythene bag???
Do people actually buy this kind of stuff, cos if they do I’m packing my job in and going into business!

Although clothing and probably outside the spirit of this article, over knee sealskin socks were my big discovery last winter – having perviously tried the short version and not seen what the fuss was about, the knee length are in a whole different league – a pair of merino socks underneath for added warmth and no bother about whether your 5 10s have dried from the wet day before. Get back to the car, whip them off to reveal clean dry legs. Just remember to dry them inside out
