I recently took the Patagonia Atom to Walt Disney World and it is officially the best bag for Disney World and the best bag for Disneyland, too! In fact, I'd go so far to say it is the best day pack. It is small enough to not break your back over a week-long Disney vacation but it was big enough to hold a pretty decent amount of stuff!
Here's what I put in my bag:
Mophie Charging Case for iPhone (x2) (I use the Juice Pack Plus, but had a Juice Pack Helium too!)
My Sorcerers of the Magic Kingdom cards
Chapstick (Sugar rose lip treatment by Fresh)
An Umbrella (totes umbrella)
Then, I carbinered my CamelBak Groove filtered water bottle and I was done!
I fit all of that in my Patagonia Atom! The sling pack is seriously like a Mary Poppins carpet bag in daypack form!
As you can see, there are many pockets on the Patagonia Atom. Other features include a tablet pouch (a little mesh pouch inside the atom; I just used it to keep my wallet in one spot), a mesh zippered pouch inside the Slingpack, a shoulder strap pocket with a sort of sunglasses case lining to prevent scratching, an almost hidden zipper pocket on the side to go against the back that has the same lining which is perfect to hold a smart phone, the adjustable buckles to carbiner or hold onto any extras and an awesome breathable and comfy back and shoulder strap! I love how easy it is to get into the bag while in motion and in general. Instead of having the take the entire bag off, I can just slide the bag around my body and get into the zippered areas quite easily! I don't even have to remove it by putting it over my head, there's a buckle I can easily unclip! For a more active trip than a Disney vacation, there's even a waist belt that can keep the pack tight on your body.
In their words...
"The single-strap design makes it simple to access your things - just spin the Atom around to your chest. The large zippered main pocket has mesh and stretch-woven pockets inside (also zippered) to organize small items. A convenient zippered pocket on the shoulder strap has a soft lining to protect valuables; adjustable buckles lash any extras to the outside. Breathable 3-D spacer mesh pads the shoulder strap and back panel to wick moisture, dry quickly and increase ventilation. For biking and hiking, an integrated waistbelt keeps the pack close to your torso. Made of a 420-denier 100% nylon oxford plain weave, with an 840-denier 100% ballistic nylon bottom. The lining is 200-denier 100% polyester. All fabrics have a DWR (durable water repellent) finish.
Here is the example of packing it that Patagonia gives:
All in all, I really loved this bag for my Disney vacation. It will be one I use not only for trips to Disneyland or Disney World, but a bag I will use as a day pack around the city and even when I go hiking. It would be a great hiking day pack for short hikes. If you are in the market for a smaller, efficient bag for a Disney trip, I would definitely suggest the Patagonia Atom. At $45.00 it is a reasonable price (especially if you buy it from R.E.I. with a coupon like I did, bringing the price down to about $36.00). I would definitely suggest looking into this bag for a day pack, no matter where your journey may take you.
I was not paid or given this product complimentary from Patagonia; I bought the bag with my hard-earned money and just want to share its awesomeness with you!
