I've never been a fan of plastic sleeving.  The material is usually coarse, stiff, and gets wider when bent. Sometimes you can see the wiring inside when it's bent.  And it just looks "plasticky".

I saw fiberglass cloth in an audio catalog (Micheal Percy) a few years ago and gave it a try.  Fiberglass cloth sleeving has a much nicer look and feel to it.  It feels like cloth in the hand, and has a non-shiny fabric look. It's much more flexible than plastic and does not fatten up at the bend points.  It's also completly opaque so you won't see the wires inside.  It's very strong and won't melt under soldering temps.  It cuts with sharp scissors, and is easier than plastic to thread wiring thru.

On the down side, fiberglass sleeving only expands in width to about 150%, so you can't "overstuff" it with wires.  Plastic can probably expand 300%, but I personally don't like this feature, it tends to look "exploded" and shows the wiring inside.  I've only seen fiberglass sleeving in black (not counting specialty stuff).  You do have to put heatshrink (or tape or zip ties) over the ends or it will start to unravel.  You can't melt the ends or cut it with a hot knife.

I've attached a sample picture of some sleeving I have.  The top two sleeves are high-quality plastic, and the bottom three are fiberglass.  The fiberglass looks even better when cabled up and terminated.  Unfortunately all the fiberglass cables I made are in a PC that's at a friend house.

I'm fortunate to have a surplus shop nearby (Skycraft) that sells the stuff by the foot.  I hope more PC vendors start carrying fiberglass sleeving so maybe we get more colors choices, widths, etc.

FYI - I have no business selling, marketing, or making any sleeving, cables, etc.  I'm just passing on a preference.   Best wishes!

you should check out mdpc-x.com :P amazing sleeving. but nice idea on the fiberglass

Any of the sleeving I've done will not match the craftsmanship of pros like mdpc-x.  My post is to simply let people know about an alternative material for cable sleeving.  I hope the sleeving pros like mdpc-x offer fliberglass sleeving and teflon insulated wires as an upgrade.  I think that would be a much better product electrically and mechanically.  Everyone has their own opinion about what looks best to them, and if someone likes plastic sleeving, then that's great.  I personally don't like the look, feel or mechanics of plastic sleeving, and that's kept me from purchasing pro sleeved cables.
