UKC

I'm trying to find out the above information, and since their demise as 'sack makers thanks to being bought out by Planet X, I'm slightly stumped as to where to look.

Does anybody know how long their medium back length rucksacks were?

Many thanks.

Back lengths (in 2013)

Size 1 = 37.5 - 42.5cm
Size 2 = 42.5 - 47.5cm
Size 3 = 47.5 - 52.5cm

What the actual length of the rucksack might be would depend on the 'harness length' and maybe the model of pack.  Here's a page from 2016, which was definitely after PlanetX had bought the brand:

I can measure a Black Ice long back from pre Planet X era if that helps at all.

Yes please, that would be handy. Did they only ever come in 2 back lengths, or was it 3 do you know?

I've figured out that the rucksack I have is a size 3, and that a size 2 I had my eye on 'may' be a better fit, if the seller relists it again on ebay. 

My Podsac is, I think, size 2. It doesn't have a floating top. I've had it 25 to 30 years - it's pretty tough I'd say. Back measures 50cm
