What size of daypack is everyone using? on 11/22/2011 21:13:21 MST Print View

I am curious to know what size of daypack everyone is using? Anyone get away with 15 to 20L with the ten essentials? For day trips, not a planned overnight.

Consider no day pack at all on 11/22/2011 21:17:05 MST Print View

I often dayhike with a bota bag for water and everything else (including a sandwich) in the pockets of my pants, shirt, and vest.

I had considered using a small fanny pack to get close to your approach. My issue is that in the Rockies, I always get hit with rain at some point and the wind is pretty significant at higher altitudes which means extra clothing.

REI Flash 18. I took the bladder pocket out and removed the waistbelt (the "suspension" can't carry loads large enough to warrant a waistbelt).

I have a 20L daypack that is used for trips where I need to haul a lot of water, insulation, or other gear.

I also have a 6L running/biking pack that I take on most 3-season hikes. I like this size because it allows my back to breathe and has enough room for water, a shell, an insulation piece, my random accessories (e.g. wallet, phone) and not much else.

The 20L is cavernous for most of the stuff that I do around the bay area.

REI Flash 18 here too. I stash my 7oz rain jacket in the bladder pocket to make for a cushy back panel.

For longer distance dayhikes through rough terrain or desert environments, I use a heavy duty Osprey Atmos 35 but think something similar but lighter in the 25L range would be perfect.

I rarely go on a day hike where I actually need to take all ten of the essentials but no matter if all I'm taking is a couple of bottles of water or all ten essentials I always take my Flash 18. I'm kind of irrationally attached to this awesome little bag. I left the bladder sleeve in since it's great for holding a bit of CCF pad in and the little pockets are good for the small stuff. Someday I hope to be able to fit everything for a weekend in it, but for now I love it for my da hikes.

As far as I know, I have 3 essentials. Water, food, and insulation.

I've gone all day with a nathan hpl 20, (about 3 litters).
This was going up in the high sierras and way above 10k feet.

I think about 6 litters works a little better.

Thanks guys. I am trying to go from using a 30L daypack to something under 20L. Quite frankly I like what Aaron said about the essentials - I seem to take more than I really need. Time to trim back and use a smaller pack.

+1 on the REI Flash 18. great design, and weighs about 9 oz. 18 L is more than enough for me do carry all I need for a day hike.

S2S ultrasil day sack on 11/22/2011 23:32:11 MST Print View

Sea to Summit Ultrasil day pack - about 20 litres and 70 grams. Carries the basics and 1 to 2 litres of water. Shoulder straps could be better. PLanning to have look at the Sea to Summit Dry Day Sack which looks a little larger and better straps. May be able to do a summer overnighter with it.

Camelbak Hawg and Dakine Nomad. 19L and 18L respectively. Use these for both mountain biking and day hiking. More than enough room for a FAK, probar, water, and rain/puff jacket. Even a full bike repair kit when I'm biking or patrolling.

When day hiking I don't really worry about UL. With as little as I'm taking, I hardly notice the pack on my back. I also, usually fill up with 3l of water so I don't have to bother to stop to refill during the day.

13L on 11/23/2011 00:22:39 MST Print View

13L mec bullet pack that cost ~$16

for rock climbs with the possibility of getting stuck with temp down to 20F

there a rain jacket, a down poofay, a synth poofay, a blizzard 40F survival bag, water, food, headlamp, first aid kit, etc ...all in there

very survivable down to 20F ... id dont always bring all the stuff depending on conditions ... weight including water and food ~5-6 lbs or less depending on what i bring

youd be surprised at what you can stuff in a very small pack with modern UL gear

I have a Vaude Trial Light 12 is just enough for essentials, a shell, a couple water bottles and a snack. It is an older model with water bottle pockets on the outside, a feature that I really like and has been eliminated from the current model. I adapted the waist belt to make it removable but cutting the straps off, leaving 2" and sewed 1" ladder locks in place so a belt can be added. After using it for a while, I probably wouldn't bother. It also makes a great urban pack with room for a rain shell and a camera, but is small enough that it is easy to maneuver doorways, buses and crowds.

I just got an REI FLash 18 and I'm surprised how well it carries. I wish it had water bottle pockets. 18 liters is plenty for a day hike if you are sticking to basics. It had good room for a puffy layer, a rain shell, food, water and essentials. It isn't big or stout enough for carrying a DSLR kit or other bulky/heavy toys.

For a no-compromise day pack, I use an old-style Osprey Stratos 24 ( It isn't a lightweight at 3 pounds, but I can throw the kitchen sink in there and carry it comfortably. It is a "trail office." I had a Talon 22, which is a fine pack, but it wasn't quite big enough and the side pockets were too small. The Stratos has large side pockets that will handle a point and shoot camera or a small GPS, a well as snacks, insect repellent and sunscreen. The back panel is a trampoline style and a joy on a hot day. The pack is fully framed and gives great weigh transfer. That trampoline frame creates a curve in the pack, making it appear larger capacity than it is, but the water bladder rides in there, reclaiming some space and isolating the water from the electronics in the pack. You can remove and replace the bladder without unloading the pack. I don't like the water bottle pockets-- they are too small for typical one liter bottles and they will poke me in the ribs. I found that recycled springwater bottles with tapered tops will clear my ribcage. The side packets are stretch mesh and I've found them handy for a bandana and gloves. There is a bog stretch pocket on the front that I like. I keep a Z-seat CCF foam sit pad and my maps in there. I could do a summer overnight trip with this one and SUL gear--- SUL for compactness as much as light weight.
