This pant has a relatively large pocket and it can be closed by a set of magic tapes. It helps safe trip by putting passport, cards and bills on the pocket, closing by the magic tapes and wearing the pant under a trouser. It dries relatively faster.
The drawback of this pant is that it occupies much space in a bag.
I purchased it at an Onnut branch of Tesco Lotus. The price was Baht 99 (nearly $3).
