Simple and chic

I've used it several times

Was looking for a casual but cute dog mom backpack and this definitely fits the bill!

The bag to get!

Got this bag about 2 weeks ago and it really met my expectation. Thule is known for quality products and I wasnt disappointed once again. I wish it came in more color options but it’s all good. Thank you Thule!

Looks nice, very light

Looks very nice - stylish and light, which is what I wanted. A few things missing — wish there was a larger zip pocket inside to store valuables like phone and wallet. The front pocket has easy open flap for those items but it’s only held shut with a light magnet and if falling off a bike or something, those things will go flying. But for general use, seems to be ok. Just got it so no idea of longevity yet. Have a Thule Crossover that is a tank, still in perfect condition after 7 years so hoping this will be made as well. Like the light colored interior so you can find things.

Beautiful sturdy backpack!

I’m really enjoying the Thule Lithos backpack since I bought it 2 weeks ago! The straps are comfortable and offer great support with a full load, the compartments make it easy to organize things (and not lose items to the bottom of a bag) and the side pouches have enough stretch to fit my Nalgene. The backpack is a little slim but I think it will stretch over time, I would recommend it for daily use but not for travel.

A great bag!!

I searched high and low for a simple black backpack that holds a 15 inch laptop. This bag fits it perfectly and still does not look awkward. It is classy and get extremely functional. It is not full of useless pockets. Holds my water bottle beautifully. I cannot say enough good things about it. ps Super comfortable …. I walk 30 mins to work and home everyday.

Great Quality and Great Look

After lots of research between patagonia, the north face, and nike/adidas backpacks, I finally bought the thule lithos 20L for college. And I feel like all my research paid off. This backpack is the perfect size for bringing all the supplies needed for class. The zippers are very smooth and feel high quality. The fabric holds its shape, so it gives the backpack lots of structure and a nice thickness. The waterbotle holders are roomy for my slim water bottle, but might not work for those huge hydro flask bottles. The front pocket snaps back into place very satisfyingly. And perhaps most importantly, it's so comfortable to wear!
