I purchased this because I thought it could double as a yoga bag and a commuter bag. However, the "laptop sleeve" is not appropriate for a laptop. It's not deep enough to fit a laptop (it only goes half-way down the back of the bag) and the "sleeve" pocket material is super thin, without any padding or stretch--it wouldn't even use it to hold a tablet.
I recently bought the yoga mat backpack and instant felt discomfort on my shoulders. I had only my light travel mat at water bottle in the pack, went for a walk, and had chaffing and redness on my shoulder. The quailty of materials is poor and caused pain. I've never had a backpack do this... I emailed the company and never got a reply. I want to return this backpack.
Vast improvement over the one I had and it fell apart in a month
I bought it carry beach towels or a picnic blanket (not always a yoga mat). Bottom straps are adjustable, so it works great. There is also space to hold quite a bit on the inside.
Went on a retreat and it was used as my carry on. Worked perfect!
