How to measure? First find a willing helper to assist you, then take a flexible tape measure or bit of string and place it on your C7 vertebrae (this is the one that sticks out when you bend your neck forward), now place your hands on the top of your hips and point your thumbs horizontally towards your spine, this is your iliac crest. Measure from the C7, following the curve of the back, to the iliac crest. 

Once you have your measurement, select the correct size. If you are right on the gap between two sizes, pick the larger of the two - i.e. a 19 inch torso should choose a Large

Small 15-17 inches

Medium 17-19 inches

Large 19-21 inches

Covid 19 update. 21st Jan 2021

In order to protect the health of our team, we have decided to scale back our production until infection numbers in our area decrease.

This will, of course, have an effect on our lead time. Luckily, we were quite well ahead on our orders going into Christmas so at present things aren’t looking too bad. Motown and I are still producing some orders, although not to our normal scale, nor at the normal work crew’s efficiency. We will aim to update the lead time each week.

We appreciate that any delay may be disappointing, but we ask for your patience as we try to navigate through this safely.

Take care of each other and please, wear a mask

Tom and the team. x
