X-pac LS21 liteskin or X-Pac VX21 or 210D HDPE Gridstop

I'm in the process of ordering a Liteway Elementum pack and wondered if anyone here has any thoughts on fabric choice.

I have an Exped pack that is in 210D HDPE Gridstop so I know exactly what that is like but have a thought that a stiffer material like XPAC VX21 might be better in a frameless pack.

X-Pac LiteSkin LS21 looks interesting but having done a bit of searching around I can't find information on the pros and cons vs standard X-Pac VX21.

I had the same dilemma when ordering my (second) pack from Atom packs (although mine was a framed pack). I had a look at all the materials and eventually decided on the VX21. The stiffer fabric is nice in that it doesn't flop around, particularly good for the roll top opening and putting contents in the pack. LS21 is strange stuff. My impression is that it is not as durably waterproof as VX21 (the outer coating can abrade, I vaguely recall seeing a video on LS07 and breaking down of the coating around seams I think), and the fabric itself seems a relatively open weave; I'm not so sure it will be as tough as VX21 but it is lighter. None of this is from personal experience, just looking at the fabric and anecdotal reports. I suspect 210D HDPE gridstop will have the best long term durability of them all, though not necessarily as waterproof.

Thanks @Robert P that confirms my thoughts. I had ruled out 210D HDPE gridstop because although great for my framed Exped Lightning I think stiffer would be better for an unframed pack. LS21 looks a bit odd. I think I might just order a funky coloured X-pac VX21 one. They have some large in stock for immediate shipment. If I could wait I'd probably buy a black one but I'd rather get one in a less desirable colour and have time to play around with packing it.

I need a new pack and have been debating this question as well. VX21 seems to be the standard choice for cottage packs atm, with good stiffness as you say. But I get put off by two things: firstly, the "X" part, since that seems to be a point of wear. I'd prefer to go with V07 or V21 over the VX options personally. I'm not sure the X-grid really adds that much tbh. Most manufacturers don't offer that option though, although some do (e.g. Palante).
The other thing that puts me off VX21/07 is the fact that the face fabric will still absorb water in rain. In an ideal world I'd choose a pack fabric that didn't do this. LS21 is one of those since the waterproof later is outermost. But as discussed above that makes it vulnerable to abrasion, so...?
Let's just say no major pack investments have happened over here yet! Although I did bag a nice homemade frameless pack in LS21 on here, so going to try out both the material and whether frameless works for me.

Was a big discussion on BPL on Dimension polyant fabrics with one of their sales engineers fielding questions. Search BPL Taylor @ DP. can read quite a bit even without a subscription.

interesting read even if you can’t find exactly what you were looking for.
