I'm not a 44 alas.
I've been looking at the ELC B-6. It does look very nice and is cheaper than an Aero B-6.
These are the measurements for sizes 38 and 40:
ELC B-6 Size 38
ARMPIT TO ARMPIT: 56 cm
SHOULDER SEAM TO SEAM: 47 cm
SLEEVE LENGTH FROM SHOULDER SEAM TO CUFF: 60 cm
BACK LENGTH FROM NAPE OF NECK SEAM TO BOTTOM OF WAISTBAND: 62.3 cm
ELC B-6 Size 40
ARMPIT TO ARMPIT: 58.5 cm
SHOULDER SEAM TO SEAM: 50cm
SLEEVE LENGTH FROM SHOULDER SEAM TO CUFF: 61 cm
BACK LENGTH FROM NAPE OF NECK SEAM TO BOTTOM OF WAISTBAND: 63.5 cm
It seems to me that the 38 would fit me nicely, as I have a 97cm chest size. I think a back length of 62,3cm might be a bit on the short side, though, so might consider having 1 or 1,5" added to that...
But ELC will not just add length to the body, they also lengthen the sleeves... Would this make the sleeves too long (61cm)?
Eastman shortened the sleeves for me and left the body length stock on a size 46 ANJ-4 about five months ago. I was told by HPA that they are not doing this anymore but it would be worth your while to contact Eastman and find out for sure. I seem to remember someone here or on VLJ had a long or short custom order since I was told that. Good luck with your purchase.
