Most certainly. I used to be able to fit everything into 1 pack. Nowadays I check 2 bags, 1 being a cooler stuffed with some things.

My pack is 65L Gregory Baltoro. Big Items I have are: Tent(REI Half Dome Plus), sleeping pad, backpacking chair, backpacking pillow, extra pair of shoes, and canopy. Keep in mind most of my stuff is all lightweight-ish backpacking gear.

Its usually plenty warm at night that I don't bring a full sleeping bag, just a sleeping bag liner.

In the bottom of the pack where the sleeping bag would usually go I pack the sleeping pad (usually a lil extra room down there to stuff some socks or undies). Then I take my tent poles and canopy poles and slide them on the inside of the bag along one of the sides. Chair goes in vertically alongside it, along with pillow. Then fill in with my clothes. The Baltoro is awesome cause it is both top loading and front loading so I have access to everything as if it was a suitcase(but the packing should be near the same if you have just a top loader.

I try to pack as minimal as I can with clothes. For a 3 day music fest I usually have 5-6 shirts(some are pretty light linen type shirts, 2-3 pair shorts, 4 sock, 4 boxers, and hoodie/lightweight windbreaker. Fashion has never been my strong suit.

Pack all that in there. Once all that packed, just cram your tent in from the top pushing it in every nook and cranny you can. Bunch it in every crevice. You'd be surprised ho well it can fit in a backpack when you don't worry about folding it. Then I would dod the same with the canopy. Usually still had enough room on the top for a pair of size 13 shoes too. All my toiletries/headlamp/etc could fit in the lid pockets and front pocket.

I also would have a small cooler bag I would take as my carry-on bag that way at the fest I could keep some food/drinks somewhat cold plus it gave me extra room to throw clothes/ water bottle/book etc for on the plane. I also have a packable backpack similar to this that I throw in there then use inside the festival.

Nowadays, since I get 2 free checked bags(Southwest or Alaska) I can take a few more luxury items like a blanket to lay on, some fun lil toys and trinkets for fest,andf I cram those and the canopy into a full size cooler and duct tape that up and count that as a checked bag. AS long as its under 50lbs its the same as any other bag and I have a full cooler of drinks and food.

I buy almost all of my meals inside the venue. Most of the food I have at camp is just snacks type things like trail mix, meat cheese crackers, etc. that I pick up from the store on my way out to venue along with beer and plenty of boxed wine. Thesecollapsible pouches barely take up any room and can hold a bunch of wine to sneak in!

All in all, I'd say lay out everything you WANT to take and do a test run to see how much you can fit in your bag. Then if its a lil tight, take it all out and eliminate 1-2 things that you might be able to do without. My 1 luxury item is my chair. It feels so good to be able to sit in a chair vs the ground after standing or sitting all day in the fest.

My first couple times trying to pack everything I couldn't fit it, but after restructuring things around a few times I was able to get it all in, albeit heavy and uncomfortable, but I wasn't;'t hiking in so just was just uncomfortable for the small times i was lugging it in.

Hope that helps. I'm happy to answer any more questions you may have too. Thats just the stuff off the top of my head.

For that you can carry one of those tiny day packs that folds into itself not taking any space (example link below). 38 liter should be your main pack, anything bigger than that for 5k is absurd.
