How to Choose Daypacks

Consider your activity

Hiking: Often compatible with hydration reservoirs, have external gear straps/loops
Running: Designed to limit bounce, hydration compatible
Climbing: Slim profile, abrasion-resistant reinforcements
Cycling: Road cycling packs compact with lower profile; MTB packs hold more gear

How much gear will you carry?

10L or less: Short runs, quick outings, casual use, essentials only
11–20L: Day hikes, cycling, can carry an extra layer
21–35L: Sweet spot for multi-hour or full-day hikes, travel
36–50L: Gear-heavy outings l(all-day hikes, climbing), winter hiking, ultralight backpacking

Internal frame or frameless?

Internal frame: More support for heavier loads, but bulkier
Frameless: Lighter weight and more compact, but less support

Find the right fit

Use torso length (not overall height) to find your pack size
Measure your hip circumference (slightly higher than your pant-waist size) and check that against the hipbelt size

Great daypack! Holds more water than needed for a long hike and the compartment space is big enough for a jacket, food jar, cellphone etc. The back is reinforced nicely so theres no bending, which offers nice support. Its Lightweight too. I Love it

i like this bag! it’s a little stiff to start but after a couple wears it’s gotten more comfy on my back. I wanted a good sized camelbak to bring on day hikes and i was torn between this and the Mule and i’m glad i got the Cloud Walker! i compared it to my partners Camelbak Mule and it is almost the exact same size, the Cloud Waker extends out more to fit more stuff but the footprint is almost identical if that makes sense. a few things that make it 4/5: - it comes with a 2.5L reservoir instead of 3L but the side pockets make it super easy to carry extra water and a 3L reservoir will fit inside if you have an extra one. - be careful with closing the reservoir. there’s something weird about the seal that makes it super finicky to close properly. this hasn’t been an issue with other camelbak reservoirs i’ve owned. it’s fine once it’s closed but make sure you have it sealed right before you put it into your bag. this is the main reason i’m giving it 4/5 stars - the shoulder strap clasp seems cheaper than the ones on my other backpacks and i’m worried it might eventually break? it hasn’t yet so maybe i shouldn’t fault it for that. overall this is a good little bag! i’m really happy with it.

The bag is nice, it is great for our day trips or just for quick walks around our lake/local communities, and I love that it has the side pockets for bottles or other items. I have not used it for any long hikes yet, so have been using it without the water pouch, but I'm sure that will work just fine knowing camelback water packs. The reason I give this a 4 star rating instead of 5 has more to do with the feel of the pack while wearing it. It could use better straps with more support and cushioning, though they are by far not the worst straps out there, just could be a bit better. I also find it leads my back feeling a bit sore even with a pretty light load, I am continuing to try different strap lengths to try to get around this and hope this is user error more than an issue with the pack design, but I have not yet been able to find a sweet spot that works well for my back. This might also be something that would improve with including the water pouch inside the pack, but that will be an experiment for another day. My rating does not take this into account since I still have faith in the pack, I just knocked it a star for not having better straps, I would love to see camelback up its strap game on their packs as this has seemed to me to be a fairly common thing when I've looked at their packs.

Purchased this to hike in Zion National Park. Our longest hike was 8 miles and I never felt like I was going to run out of water. Filled this up completely and still had room for some snacks, other hiking necessities (headlamps, first aid kit, snacks) and room to roll up my jacket when it got too warm. Definitely recommend it!

This is my favorite backpack for day hikes where I need to carry the essentials. I have used it all over the islands of Hawaii, in Mammoth and Lake Tahoe. I grab this backpack for anything from a 3-4 mile hike to an all day adventure. Not only can you use the bladder, but the side pocket fits a Nalgene bottle as well. Plenty of room for a light jacket or shirt or change of clothes, snacks, flashlight, wallet, first aid kit, etc. The strap were comfortable and didn't dig into my shoulders

Great pack! The bladder does take some of the capacity. But for day hikes works great

No, I do not recommend this product

My first camelback and I used it on a trip, the first day I noticed it leaked and I was unable to drink any water which was very inconvenient and frustrating. The next day I let the water bag sit in the sink filled and came back to see if it leaked, it hadn’t. I took it out the next day and it leaked again somehow.
