what pack am I missing? small, dyneema, modern closure?

I'm looking to fill a hole in my pack collection. Ideal (in my mind anyhow) would be something like a Blue Ice Dragonfly 18 or BD Blitz 20, but made of dyneema or whatever the right name is for these D-XX high tech lightweight abrasion resistant fabric. So,18-20L range, simple design (sack with one pocket and maybe some simple way to lash on tools), light, carries well, withstands chimneys, and with a slick modern closure like the aforementioned packs (is there a generic name for this style that I think originated on the old Patagonia Ascensionists and now exists in many variations?). 

Tufa Mochilla looks very close, and I may end up with one, but neither closure is as elegant, at least looking at it from afar (and I know people love these packs...). 

Or I'd consider paying a custom pack maker to copy one of these packs in better material, with my tweaks, if I could find one who would do it. 

Thanks for any thoughts... 

This is bigger than you're specifying, but worth a look: Hyperlight Mountain Gear Summit Pack.

exped whiteout 30, if you roll it enough and close it with the lashing point in the middle it will be and look like a 20 liters backpack.

Tufa Mochilla without question. The pack's elegance comes from its simplicity and durability.

I've had the Blitz 20 for 2 years or so, and it's held up well.  I dunno what fabric it uses, but it seems to be working. Tools are easy to get on and off.

The Tufa Mochilla looks nicer, but I dunno if it is $100 nicer.

I have a Tufa and an FL30 (which fully rolled down is like 23L or something) and I tend to reach for the FL30 most of the time. The wider hip belt on the FL30 makes it better for me, and the shoulder straps are the tiniest bit better shaped and padded for my body type.

For me the Tufa is like a 90/100 and the FL30 is like a 92/100.

Good thoughts, thank you. Some reactions: 

• You are right it's not about elegance. For me, it's also not purely about simplicity, but about the right amount of simplicity - a shopping bag is simpler than all of these packs. I prefer a single action drawcord closure/weather flap/rope holder design for getting in and out of, so for multi pitch climbs that's my preference. One man's opinion. 
• I own the FL30, great in many ways but it's a bit large for most single day stuff for me and stiff (love the FL45 tho, for multi day, go figure). 
• I blew holes in my Blitz 20 almost instantly taking it on rock climbs. Good ice pack tho. 
• The HMG summit pack is lovely and yes simple, but a bit too large for what I'm looking for. 
• The millet looks interesting. Heavy. 

Packs are pretty personal, I think, and rarely perfect. All are more than good enough though. It's nice to have such a refined first world problem to deal with.

BD Speed 22

I really love my tufa. It is burly and has some great features without being too much. Worth the money and the wait time. 

I sort of agree. Waterproof laminates seem a bit much (and it's more weight) for a day pack with modern weather forecasting. If you're going custom some 500d or 1000d cordura would probably be optimal. I mean it's not like you're trying to keep your sleeping bag dry in there. 

I believe Mountain Hardwear started using dyneema for their alpine packs recently. Never seen or felt one, but I think they also have a similar closure system to what you are looking for.

His name is actually Tom, but I can also vouch for the quality.

Duh, was literally calling him Tom in my head while reading the site name and got mixed up.

Tom's great to work with for ordering custom stuff, you can do some experimental stuff if you want. Check him out.
