This is a great pack, the phone holder in the strap has ample room - was able to fit my Galaxy Note 8 in it, which is great for hiking/walking around since I use my Gear s3 smartwatch for notifications. My only qualm with this pack is that it is not super friendly to large folk. I'm a big dude - 6', 350 lbs. - a big dude and the strap was a bit short for my liking. I love hiking/walking around/etc. so I thought a bag like this would be perfect, and in theory it is. Plan on giving it to my daughter and ordering myself a bigger one.
