“I love this pack it is great for traveling and for everyday use. I always carry my water bottle and a book with me and in a purse I would always have fatigue from carrying it on one side, however with this backpack the weight is evenly distributed and I can wear it all day without any discomfort. This little pack has such a neat little design, a perfect blend between sporty and casual. I would highly recommend if you are looking for a compact little pack. I also love that it's environmentally friendly!”

Reviews

My favorite

"I have a bit of a backpack obsession and I have been looking at this one for a long time. Late one night night in a moment of weakness I purchased it even though I did not need ANOTHER backpack. It turns out I should make decisions in the middle of the night because I LOVE this backpack. So much so I am giving away about 5 other small packs I own because this one replaces the functionality of all of them. What do I like. . . the size is not to big not to small, great for day hikes and simple day trips. Its fits my camera equipment in addition to my other items with ease without being bulky. The fabric is quality and the construction is quality. It has just enough pockets for all your things and it fits and actual water thermos in the side pocket (I am surprised how often packs won't allow for an actual bottle to fit)."

Backpack

"I haven't used it yet,,but from my previous purchases from UBB I know its gonna be a good investment for myself & the environment that we Humans sometimes dont take of,,trashing our land,,water & air and animals"

— Felix V. (5/5)

Great LITTLE bag

"I like this bag. I take it to coffee shops and on short day hikes. The large pack has a laptop sleeve which, disappointingly, is JUST too tight to fit a 14” laptop (it will fit in the large pouch, just not the dedicated laptop sleeve). The medium pouch has nice dividers so you can keep pens, pocketknives, journals, or whatever separated for easy access. The tiny pouch on top is perfect for quick access to keys/headphones. The bottle holders on the sides are surprisingly sizable - they will stretch fit a 32oz Owala brand water bottle, and keep it secure even when hiking."

— Brandon (5/5)

Perfect little day backpack

"Love this little backpack! The side pockets are perfect. I didn't think it would fit a chromebook or a three ring binder but I was wrong - my kid has managed to get both in there (though not at the same time). Loves this pack."

— Jessica O. (5/5)

Almost perfect

"This is a very cute and thoughtfully designed backpack. The straps and buckle didn't work for me, so I hope that might change in the future, but there are very few things out there that are this eye-catching AND functional."

— Anni L. (4/5)

"The commuter and travel bag Inhave been looking for. It is the perfect, compact soze for travel, while still allowing for a waterbottle and small laptop or tablet. Sturdy fabric and padded shoulder straps. Love!"

— Lori (5/5)

The perfect backpack for a day in the city.

"This bag checked all my boxes! I wanted something small, with dual water bottle holders, soft straps, and enough space to carry all the things I need. We are city dwellers and this was just the right size to spend a day out with my daughter."

— Alex W. (5/5)

Great little backpack!

"Cute backpack that I use like a purse. Fits everything I need including my 13" iPad. Love the flap closure and side pocket."

— Caryn C. (5/5)

"Its cute! The straps are a bit short but they fit me. A lot of pockets and fits a big nalgene which is great!"

— Zoe (5/5)

Colorful & Practical

Q&A

Will this fit a 13” laptop
No - it's a little day pack so not designed to fit a 13" laptops. Our 25L packs definitely will though!
Hi, what does water resistant mean. Will it be okay if your iut and about in the rain with ut?
Water resistant means it can handle light water but is not fully wate proof. It will hold up in rain, but the contents of the bag may get wet.
Do you ship to australia
Hi Dianne! Yes, we do ship to Australia.
What is the weight of this bag?
Hi Tathiana! This bag weighs about 16 oz.
Do you think you will bring back colors from prior years - specifically, the yellow/blue combo with the gorgeous "checkered" front tassel, as pictured in Emmarina T's post dated 1/30/20, or the burgundy color, pictured in Katherine M's post on 10/22/21? Crossing fingers!! Thx so much!!
Hi NC! We just launched new colors for this bag, one of them being very similar to Emmarina's bag!
