My two-penneth now. I just bought the padded shorts this morning* as I'd split my usual (non-padded) shorts last night whilst throwing my leg over the seat. I've only done my usual 5 mile commute so far but they seemed very much worth the few pennies they cost. I'd been umming and ahhing over the jersey. Still am.
*I tried on two different sizes in the Sports Direct changing rooms - a box next to the tills with a door that goes from knees to shoulders! - with my little girl (nearly four). I pulled up the first pair and my girl looked at the padding and said in a voice only little people can do 'Daddy, is that your tail. . .? Is THAT your tail? Why should I shhhh? Why can't I say tail?'. Yes, lots of people in store giving me a funny look as I came out the room.
Edit - if you are going for the Muddy Fox stuff then Field & Trek site seems a couple of quid cheaper for each item.
