Mountaineering Designs - Probably 25 years since I used them for a top up but appear to be still around.
Anyone used them recently?
They'll clean, top up down or take down out of old bags & put into new shell.

I had a bad experience with them a couple of years ago. Sent my Cumulus Quantum 450 to be cleaned. Got a message to say "they had repaired the zip and it was the best they could do - it was damaged when I sent it to them". They claimed it was worn out at the bottom and now wouldn't connect.
I was puzzled to see what was going on. When I got it back they had stitched bottom closed (double ended zip) and it had been re-connected so that at the top there was 3" difference one side to the other. My family were horrified.
Not Happy - as It had been in good working order when I sent it in. I phoned them and had a really unhelpful conversation with a guy who just laid all the blame for the mess on me. They refused to replace the zip cost free as I thought was warranted
In the end They refunded the cleaning cost and sent me the longest zip they stocked which was about 12" too short for my bag - glad I didn't get them to repair it.
I bought a length of zip from Extreme and repaired it myself. My daughter has been using it ever since with no problems.
It was their poor customer service which annoyed me the most - refusing to take responsibilty for their mess and thinking I'd be OK with it.
So up to you - I won't go there again.
