Just a quick note on the Sleenker 668L and 666J.
These are very comfortable due the stretch. The 668L has a special stretch, that should guarantee the fit of the model. It should reset in their original shape. No experience with that till now, since I haven’t wore them yet.
On the left side of the picture you see Thanaz 887K, middle is Sleenker 668L and to the right Seenker 666J.
I added the 887K, since the color tones of 668L reminded me of 887K....
