They are good, and light. The price depend on configuration. Mine came in at about 800 USD a few years back. I die not choose the tubebag solution, but after hitting a few large rocks while rafting a bit (due to the backpack blocking sight) I think I would choose to go for the tubebag solution. I did not think it would survive the collisions I had this summer, but It did and only had cosmetic scratches. Also comfy – even after using it 9 hours strait only stopping for lunch. Impressive piece of gear.

Bad Larry updates.

I recall being worried when my Arc Haul was in the back of someone’s pickup truck during heavy rain and I found everything inside stayed completely dry. I looked up Zpacks and indeed they do seam seal their packs. So that undoubtedly helps.
So I will be purchasing the $75 seam seal add on shortly.
Generally, the thing I most want to stay dry – a goose down sleeping bag – is already protected by a waterproof cordura compression sack. But even if everything in your bag is protected with waterproof stuff sacks – or you use a liner bag – if water makes it through your bag it will take on more weight.
The Ultra 200 fabric on my Arc Haul and the ultra 400 used on the Wolverine are highly waterproof. So seam sealing should be enough to not need to worry about using a pack cover or a liner bag – unless you do white water rafting and expect total submersion at some point. But then you can stuff your bag into the raft itself on some models.
Hopefully I’ll get the Wolverine in time for some snowy expeditions this winter.
If I were choosing an expedition pack, especially where I’d been carrying a hot tent, I’d choose Seek without any doubt but would look hard at their breakaway configuration.
As you may already know, their backpacks come in either the integrated or breakaway platform. On the latter, the main bag separates from the frame allowing you to put another bag between the main bag and the frame. That is particularly useful if you have bloody meat or dirty vent pipes that you do not want to stain or soil the mail bag.
Moreover, for those who do have a hot tent, the breakway feature is also helpful because you can load a lot of wood into a bag and also keep if from damaging the backpack’s main bag.
I have the Seek 6300 in both configurations (Unaweep and Goshawk). If I could only keep one and I didn’t hot tent not hunt, it would be the Unaweep. If did either of the other two activities, it would be the breakaway configuration for sure.
Thanks for pointing out the benefits of the breakaway feature of the Seek Outside packs BPLwiia. I’m definitely several notches of experience away from hunting for game and needing to carry back large quantities of meat. 5 or 10 years from now maybe I’ll be into that. Bow hunting appeals to me. The stealth of it. And the old school part of it that doesn’t rely on modern technology. I’d probably start with fishing as a means to obtain protein. You’re not a true outdoorsman until you start obtaining significant quantities of food from your natural environment.
For now, hot tenting is a specialty focus that I do enjoy in a certain time of year. Only done 2 trips so far with my Naturehike Massif 2P. But I loved it. I use a thin titanium pipe that rolls up in a single compact small piece. Then I can put it away along with the fold down stove in it’s own carry bag. I got my AMG 105 so I’d have room to carry it plus other gear.
I like the idea of a drone backpack. That way you can stash most of your pack weight for a little while so you can do a water run or reach a summit more easily. I just got one of the 4Monster UL nylon ones on amazon. 32L size is just 4.4oz. Obviously can’t put anything remotely sharp in it. But it is an impressive volume to weight ratio that takes up very little space in my pack when empty.
For carrying wood though, it can be handy to have a bag so you don’t have to manage a bunch of small pieces. It also saves your clothing from being poked. I’ve gotten by ok just bringing a disposable shopping bag that weighs almost nothing. But if I have a thick log to process, I’ll just carry that by hand as it brings a lot of firepower in one single piece to carry. I usually prioritize camping in proximity to lots of nearby wood.
One benefit of bringing a saw is that you don’t have to scrounge for wood far and wide as much. A few dead standing trees and or dry deadfall that isn’t too punky and you’ve got hours of fuel for a fire that doesn’t need to be babysat as much. Also burns hotter with coals that last longer for grilling.
