The champ sys bib shorts are well good, even the cheapest ones. Actually the jerseys are really nice forthe money too. Drawback being that iirc you have to order 10 jerseys to start your order off (any combination of sizes eg we got a couple of ladies, kids long sleeve and baggy/dh ones included in our minimum of 10 jerseys. Then whatever shorts/gilets etc on top.
So you might need to persuade your company that they want to kit out more people than just you, (hey, what about a whole ‘vélo club de stumpyjag’ team? 😉 ) and for this they will be parting with the thick end of at least £350 even if they manage not to pay VAT
Cheapo way will be to take a couple of plain jerseys down your local screen printers/stag and hen t-shirt place, -our ‘team’, (and I use the word in its loosest definition!) got a screen printing mate to do this many years ago for our first kit, but it doesn’t work too well long term with a lot of stretching, it cracks, wears and fades fast in mud/grit, and won’t work on bibshorts.
