This airtight vac suit made by http://www.seriouskit.com/ who incidentally make the iconic Serious' Kit milking machine, is now available for sessions. A minimum session time of 2 hours is required plus an extra charge of £40 which brings the total charge for a 2-hour session to £300 for the inclusion of the suit.

If you'd rather a Vac bed, I have a couple at my disposal, but please say if you'd like to include any of the items mentioned so they can be out and ready for when you arrive.
