A running bottle is a lightweight, leak-proof water bottle for use on the move — handheld (500ml), belt (500ml), or running vest (2× soft flasks). For runs under 90 minutes in Indian heat, an insulated handheld 500ml is the best pick. For half marathons and beyond, a running vest with soft flasks. Cold water in Indian heat is a real performance lever — insulation matters more than most runners realise.
