What are those strings holding the caps? are they for the air chambers or are they the caps that stop water coming in?
Also did you guys take a backpack at all? Me and my wife are looking to take a backpack aboard with us but looks like there isn't much room for much else apart from us 2, we ordered a drybag backpack and going to store a couple of small towels in there incase we fall in, change of clothes, change of shoes (going to wear water shoes once we get in) and 2 large bottles of water. Just not sure where we can fit it, it would have been great if intex included some webbing on the far back or front of the kayak like they have on the challenger, or I thought about a DIY job and attaching something like this to the front or back end https://www.amazon.co.uk/OXFORD-Strong-Elasticated-Webbing-Coated/dp/B000R566T2/ref=sr_1_7?crid=11VTUTVI2Y3FY&keywords=elasticated%2Bwebbing&qid=1661410684&sprefix=elasticated%2Bwebbing%2Caps%2C102&sr=8-7&th=1
