Thanks,
novalemon! From what I've seen of pics of Burgundy online, and from what I can recall of seeing the Burgundy Logan in person some time ago, yep, I think the Navy Logan may be a tad more structured than the Burgundy Logan. The Navy leather is still soft, but not that slouchy (though that could also be due to the inherent shape of the bag). The leather does also feel a little bit thicker than some of the other lambskin Botkiers I have (black Aiden crossbody hobo and crinkle black Venice Feed Bag), though I can't recall how it compares to Burgundy and I haven't seen Moss in person.
I haven't really broken my Logan in, frankly, as this is more of a weekend bag than a work bag for me (all those zippers and tassels are just a tad too funky for my office!). I really should try to use it more often!

Will try to post more pics if I get it more broken in...
And yep, I've seen the new colours of the Howard St satchel --
love the Indigo!! It's a pity that they're exclusives only for
Nordies, though, as I generally try not to pay full retail, and shipping would be an additional killer for me (I don't live in the US)...
