acer spin 5 sleeve?

hi, just bought a spin 5 (tha i7 processor one) which works nicely, but i'm looking for a good sleeve. Does anybody know if there are sleeves for this? or if there are convertib'e sleeves at all? cant really seem to find one.. it,s 13,3 inch, so if there"s no special sleeve i'll just go for a regular 13'3 inch sleeve, but of course i'd like to get something thtats actually meant for a 360 screen
