Hey Thanks for your message. Inside this large pack, no pockets for inserting a armour plate. Best Xmilpax team

What is the largest item you could put in the main compartment? i need to pack a tent that when folded is 18"h x 15"w x 4"d

Hey there. Thanks for your interesting in our pack and your message. Fortunately, the main compartment is about 24"h x 15"w x 7"d. So it is no problem to pack your tent. Pls see the video here. The white foam size is about 23"*15"*5" which could be loaded in easily. If any more questions, pls feel free to reach us any time.

So in the headlines it says that it can take water bladder in the middle or both sides but n the Q.A. section there saying no so witch is it cause ???

Hey In the current version, it has one webbing loop to hang bladder both in 2 side pockets. And in main compartment, it also have two interior side pockets which has webbing loop to hang bladder. Pls see the video attached here. Best XMILPAX

for a light rain yes it is good. Heavy rain the inside main pouch is protected but outside pockets are not. I would not want to try and float down the river with it. It is a fantastic pack. I can place all my camping needs in this pack. I would strongly suggest whatever you put in the outside pockets be in a plastic bag.
