how large is your pack?

45ltr during the summer and bloody huge the rest of the year ;-)

My main pack is ~2850 cubic inches. I also have a small frameless pack for summer weekends and a large semi retired 3600ci frameless pack I used with a Ridgerest burrito style.

40 litres seems to be working well for me so far.

I use a sub 4 pound 75 liter pack that allows me to easily fit everything inside, carries bear canisters easily, and can haul climbing gear when needed. The substantial frame makes heavier loads manageable. I really dislike cramming everything into smaller packs

I have a 68 liter capacity but this pack allows me to get much smaller during the summer months due to all the compression. It works for me year round basically.

My ZB-2 (long torso) is just a tad smaller than my old circuit was so maybe 60 literish. With a relatively non-compressed (poofy) 20°F EE quilt and stove it's a bit of struggle fitting a weeks worth of food but can compress it after a few days of eating.

ULA Circuit / 68L

60L seems to be about right for me. It becomes a little tight when I'm carrying a bear canister, but that's to be expected.

I don't compress my sleeping bag much, and don't fuss with my collapsed air mattress (just fold it), but a week's worth of food tends to take up some room (at least, the foods I like to eat).

Well, I use a GG Murmur for everything up to two weeks. Then I switch to a larger 2400ci Gorilla…all in food and fuel, or if I am doing some long distance fishing.

EDIT:
I can fit three stuff sacks in it. One for bag/cloths, one for food (1 week) and a second one for food if needed. I use a small tarp, about 1lb in sil that just fits into a grease pot. The pad, is my frame on the pack. My water bottles fit into one pouch and my stove in the other. Fuel, rain gear, etc goes into the front pouch. My ditty bag, doubles as a rock sack and has the Steripen Opti and flashlights(I carry two.) Duct tape, a couple alcohol prep pads, DEET, etc also goes in there along with a few days worth of AM drops. For one week, it fits easily into the Murmur. For two weeks, it's just full. I usually bring fuel enough to warm up water and wash up at camp every night. Even if I get grubby during the day, rinsing off makes me feel much better about rain and mud.

Yup, smaller usually means lighter, besides using a sub 1pound pack. Volume is not a problem, total carry weight usually crops up before volume does.

Oh come on now, it's pretty small . . . but I know how to use it.

My Osprey EXOS 58 is, strangely, 60 liters B/C I got a size Large.

I use aftermarket, add-on side pockets mainly for the convenience of having some gear like 1st aid kit, water treatment or potty kit readily accessible. But they do add about 800 cu. inches of storage space as well.

P.S. I have an old Dana Terraplane that is around 7,000 + cu. in that I now reserve for winter use. Great pack but WAY too heavy at 7.5 lbs.

I can squeeze stuff into my 2lb Zimmerbuilt @ around 45L

Im becoming lazy and am starting to use my 4lb Cilogear Worksack 40B @ around 45L but extending to 60L.

Depends on: how nerdy I wanna be, shelter choice, weather (obv)

Edit- wrong weight

is circa 46 liters. But I need a bigger one for the longer trips. More than 7 days of food.

Should also be asked how big of a person you are?
Some people are small and get away with smaller items, versus us larger people. XL clothing, larger pads and sleeping bags.
I use a 50 liter Zpacks Exo.

Exos 48 liter, 3 season, no bear canisters needed (yet). Carries well full or nearly empty compressed for day use if needed. On a side note FWIW I wasn't too sure about a tramp back pack but last week it turned very hot very fast here and I stopped quickly at brook crossings to soak my bandana with water. Squeezed it down the back of my neck to soak my shirt. Any slight breeze blew behind my back. Felt like an air conditioner. Very cool! Pun intended.

40L HMG for 3 season, 60ish or whatever a ULA circuit is for winter/longer trips.

I can squeeze my gear into a much smaller pack, but I like having the extra space of a 60L pack so long as the compression is good. The compression on my katabatic artemis is great so I've use it for bc skiing day trips as well as a 5 day trip this past winter.

Somewhere around 3000ci (50L) seems to be the sweet spot for a general-purpose 3-season pack on trips up to a week. Smaller than that I I start to have trouble cramming my food in.

But I've outgrown my fanatical phase and am now carrying about a 13-pound base pack weight. I've made weight sacrifices to carry a torso-length ThermaRest pad, in deference to my aging carcass. I usually use a 30-degree down bag instead of a quilt. My solo tent is an MLD DuoMid: a palace for one, but a flat cuben tarp would be lighter. I tend to call a "real" knife (Mora) one of my luxury items. Etc.

My gear has gotten to the point where I can pack a weeks worth in my Circuit without even trying, which means it is too big. My project pack I made a little smaller, 35L or a touch less in the main body,vs 39L in the Circuit, with a lot less volume in the external pockets. This should work okay and I can always strap a stuff sack on the bottom at the start of a trip. A slightly large pack is nice as the sleeping pad and quilt don't have to be gotten to their tiniest possible sizes to fit in the pack.

"Oh come on now, it's pretty small … but I know how to use it."

chad, i can't believe you're the only one!

I'm at the point now where weight isn't really my top priority – it's the number of things I'm carrying (simplicity) and how much room they take up.

I started with some huge monstrosity (gregory) back in the day that empty nearly weighed what my base weight is now. Then I went to a 33L osprey for a while…not sure how big my zimmerbuilt is (50-60-ish?) but it's way too much if I'm not carrying a bear can. I'm thinking of trying a 40L for a while. But after spending so much time/money on reducing weight, I've completely lost touch with volume these days.

I figure if I have less stuff, then I won't need such a big pack. Maybe.

Exos 58, but the 48L version would be plenty for "3 season" out West since a 7 day/6 night trip is the limit of a week's vacation. Those are wont to be on either edge of winter for me, plus I don't care to compress my down stuff too much, so give myself some extra room.

I have no idea what size my pack is. I have a ULA Relay, which they don't make anymore. I sewed a stretchy piece across the back where the shock cord is so I can put things there with more security than shock cord alone. I also have a lot of hip belt pockets attached in various places. It's not the 4000cu in of my old Gossamer Gear G4, but it's a lot more than whatever it was originally.

50L but the CCF pad takes up a LOT of room.

.5in thick it takes up 1.5in on one wall!

Up to six days I have not needed anything larger than a 45 to 48 liters. That includes lots of insulation and other comforts.
