I purchased the Huawei MateBook X Pro. I did this simply because I wanted something light and portable. Although it doesn’t have the battery life that the Lenovo Think Pad does, the MateBook is very light, slim and portable. After a small amount of use, I can say that the build quality is great, and the keyboard is also nice and not that of the new Apple macs. Overall I believe I made a good purchase. If you are looking to get the Huawei MateBook X Pro and need a sleeve for it, this one off of amazon fits very nice and snug.

I got this Dell 13" sleeve and it fits like a glove, has option for a shoulder strap and a small accessory compartment. It's quite beautiful too. Best option I found when shopping for one. LINK ON AMAZON
not sure if this is what you are looking for but someone suggested me this and it fits MBXP just about perfectly and i just slip this into my school back.
I got the Dell Professional 13 sleeve based on another member's recommendation and really like it:
It's very nice - perfect fit, I like a sleeve with handles and the option of a shoulder strap, and a zipper pocket for accessories. It's nice quality, textured zipped pulls, hidden zipper, good padding. It's got an MSRP of $30, you can get it for $10 now on amazon

bought this for $7.99 from Amazon. Even though they say the size doesn't fit, it actually fits perfectly. Slips right in, like a glove.
