The MESLE Totora is a robust double action pump with up to 29 psi (2.0 bar) pressure for inflatable SUP boards, kites, tents, inflatable boats, etc.. It easily provides the required air pressure of 1.0 bar (15 psi) for modern stand-up paddling boards. The pump can be quickly switched between single and double action by using the plug. With the deflate function, you can extract air to reduce the pack size of the board or boat.
