Dwayne Bravo's side has not played an ODI since a series against England in March, subsequently playing Twenty20 and Test cricket at the ICC World Twenty20 and then against New Zealand.
However, despite a gap of almost five months, the squad shows few changes with Kieran Powell, Marlon Samuels and Dwayne Smith missing out to accommodate the fit-again Gayle, Pollard and Roach the only changes.
Bravo himself missed the New Zealand series due to injury, last playing for the West Indies at the ICC World Twenty20 in April.
The West Indies play the first of three One-Day Internationals against Bangladesh on 20th August in Grenada.
They will then play a single Twenty20 International and two Tests.
West Indies ODI squad: Dwayne Bravo (captain), Darren Bravo, Kirk Edwards, Chris Gayle, Jason Holder, Nikita Miller, Sunil Narine, Kieron Pollard, Denesh Ramdin, Ravi Rampaul, Kemar Roach, Darren Sammy, Lendl Simmons
