For the first time in the history of the Finnish army, the soldiers are actually issued a dedicated pouch for the water bottle. Takes the 1 quart US type canteen along with the more rectangular Finnish model.
The pull tabs are operated by yanking them slightly sideways. If pulled straight, they won't open up as easily. They can be secured pretty well (i.e. for a parachute drop) by running the additional plastic tabs through the loops before closing the two-prong main tabs.
Made of military-grade Cordura, with PU-coating on the inside. The quality is excellent overall, as should be expected.
