create product page with views

I am having a similar issue - I want to have a different view on seperate product pages (for examples) Tshirts / Vnecks / Tanks

How would I go about this?

To determine the product to display from the URL, you have to use what Views 3 calls a "Contextual Filter" (was an "Argument" in Views 2 and prior). The problem is that for products, the only argument Drupal Commerce provides at the moment is by Product ID. You actually can't use Product titles, because they're not unique, but an argument could be written that works based on Product SKUs, which could still contain search engine friendly terms.

Here's an example View that will get you part of the way there:

$view = new view;
$view->name = 'product';
$view->description = '';
$view->tag = 'default';
$view->base_table = 'commerce_product';
$view->human_name = 'Product';
$view->core = 7;
$view->api_version = '3.0';
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */

/* Display: Master */
$handler = $view->new_display('default', 'Master', 'default');
$handler->display->display_options['title'] = 'Product';
$handler->display->display_options['access']['type'] = 'none';
$handler->display->display_options['cache']['type'] = 'none';
$handler->display->display_options['query']['type'] = 'views_query';
$handler->display->display_options['query']['options']['query_comment'] = FALSE;
$handler->display->display_options['exposed_form']['type'] = 'basic';
$handler->display->display_options['pager']['type'] = 'full';
$handler->display->display_options['pager']['options']['items_per_page'] = '10';
$handler->display->display_options['style_plugin'] = 'default';
$handler->display->display_options['row_plugin'] = 'fields';
/* Field: Commerce Product: Product ID */
$handler->display->display_options['fields']['product_id']['id'] = 'product_id';
$handler->display->display_options['fields']['product_id']['table'] = 'commerce_product';
$handler->display->display_options['fields']['product_id']['field'] = 'product_id';
/* Contextual filter: Commerce Product: SKU */
$handler->display->display_options['arguments']['sku']['id'] = 'sku';
$handler->display->display_options['arguments']['sku']['table'] = 'commerce_product';
$handler->display->display_options['arguments']['sku']['field'] = 'sku';
$handler->display->display_options['arguments']['sku']['default_action'] = 'not found';
$handler->display->display_options['arguments']['sku']['default_argument_type'] = 'fixed';
$handler->display->display_options['arguments']['sku']['default_argument_skip_url'] = 1;
$handler->display->display_options['arguments']['sku']['summary']['number_of_records'] = '0';
$handler->display->display_options['arguments']['sku']['summary']['format'] = 'default_summary';
$handler->display->display_options['arguments']['sku']['summary_options']['items_per_page'] = '25';
$handler->display->display_options['arguments']['sku']['glossary'] = 0;
$handler->display->display_options['arguments']['sku']['limit'] = '0';
$handler->display->display_options['arguments']['sku']['transform_dash'] = 0;
$handler->display->display_options['arguments']['sku']['break_phrase'] = 0;

/* Display: Page */
$handler = $view->new_display('page', 'Page', 'page');
$handler->display->display_options['path'] = 'product/%';
