I’m looking for the hose & adaptor that plugs into the 2Q USGI square canteen bladder screw top lids I know there’s gas masks that have them, but I can’t find just the hose & plug in adaptor Can anyone sleuth around?
Edit: I have found a DIY to do this . Not paying like $100 + CAD plus brokerage fees / CBSA Customs duties for two canteen straw kits will post up my workaround
