Thanks all
. leggings and bump bands it is for now!
I've found a great company in the US called Mountain Mama, who do technical maternity outdoor clothing. No good for this weekend, but Jez has a meeting over there in 2 weeks, so I'm going to order some stuff and get it sent to his client's place.
Can't help thinking the niche retailers here (Epicentre, Needlesports, Joe Browns) are missing a trick! Wonder if any will offer to distribute Mountain Mama gear in the UK in future?
