I will get back to you with an answer this evening - Carol
A few corrections/updates:
(i) They are model E 36, I think that's the older version of E 360s. Official carrying capacity is 22 lbs. per case.
(ii) They are actually not faded, just a little dusty and with a few scratches. I am wiping them off before packing.
(iii) Do have internal straps
(iv) I forgot there is a set of Eagle Creek liner bags I used with them, which I'll include. Not custom fit but essentially the right shape/size.
