I did not like to use a sleeve pocket, one makes a mess, it flows, the end caps are not suitable etc ... But the !!!! AWESOME. The pouch holds the right in its support (very convenient for pouring contents), there are several tips diferents there are 2 pockets (250ml and 500ml) and a clip to close the top pocket as it is used.
The only small problem is that the tips can be do not take very well to the support, they fall easily !!!
