If you have the woocommerce object, it is easy to get the cart. If you have the cart, it is easy te get the product info. Here is how:

global $woocommerce;

$cart_items            = $woocommerce->cart->get_cart();

foreach ($cart_items as $cart_item_key => $cart_item) {

    $_product = apply_filters('woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key);

}
