Hard to say from just a photo, but either the first or last looks fine.

Ya dude, it is a little hard to say, judging from the pictures alone. There is nothing next to them to get the scale of their sizes. Since you are asking if they will be too big, I’ll assume they are fairly large. When first looking at your pictures I was thinking they ‘looked’ too small If that is the case, then I would say that they should be fine. Since you already own them, you will save yourself some money from having to buy a new one. Try packing them with everything you intend on bring, walk around with it on, and you’ll get a good idea if they are right.

Cheers
