Suggestions for more durable daypacks

I'm looking for a new daypack. Something in the 25-30 liter range compatible with a 6 liter hydration pack.  I just retired a Black Diamond Sidewinder with something like 15,000 miles on it.  I've looked at all the standards, BD, Osprey, Mammut, Patagonia, etc.  They are all using around 100-200 Nylon.  That's way too lightweight for my uses.  I tend to hike 30ish miles a week with a lot of off trail and bush whacking.  I don't mind paying a premium if someone knows a custom or non mainstream brand that's running closer to 400d as a main material.

These are pretty burly:

Suggestions of bags with 400D material or higher:

Metolius Mescalito
Exped Whiteout 30
Exped Black Ice 30
Exped Serac 35
Cilogear guide 30
Ortovox Trad 35
Mountain Hardware Scrambler 35

Creek 35

I just got a cold cold world bag and it seems way tough.

Why not go for a brand name pack built for the military? They tend to go for 500D and up? Something made by Mystery Ranch or something similar? 

If you don't like the military color options, I have a Fjällräven Bergtagen 30. It's made from a heavy flatwoven polyamide and it feels like it's at least 600D or something like that. On top of that it also has a hydrostatic head of 20k mm. 

CCW (Cold Cold World) out of New Hampshire (I believe) makes burly packs.

Randy has been super helpful and will sew add-ons if you're looking for something specific that doesn't come stock.

mammut trion and trion gude. 

I have a Tufa Mochilla with X-50 and I think it might be *too* durable.

Convince Mountain Hardwear to bring back the Scrambler 30 OutDry. 400D with an extra rubbery lid. My cams poke holes in other packs.

Or find one used, but not until after I buy a spare for 5 years from now. 

Maybe this?

Just get a CCW. 

Thanks for the suggestions, I'll look through all of these.

Hyperlite Mountain Gear makes a full woven dyneema summit pack. Strongest material available for packs. Cold Cold World Ozone is made with 1680D ballistics nylon.

Alpine luddites all day. I’ll never have to buy that size pack again. His craft is so worth the money!

Looks almost spot on but he's 28 weeks out.

It’s absolutely worth the wait. He isn’t some industrial throw up fabricator. He treats each thread like it’s his own.

Ok, I'll keep the mammut I ordered and go about ordering a custom one of these in the White Light series.  I like the customization/fabric options and time goes by quickly.  Thanks for the link.

Mystery Ranch on the list yet?

It's not lightweight but it'll last forever. There's still used Dana stuff floating around, too.

Arc'teryx's Alpha FL series is pretty damn tough.  Dependent on the queue, have Alpine Luddites sew you something bulletproof to spec. I hear his wait times can be pretty unrealistic, though.
