Isothermal bags and accessories

Insulated bags are specially designed bags with layers of thermal insulation that keep food and drinks at the ideal temperature (cold or hot) for extended periods. The main benefits include preserving the cold chain, prolonging food freshness, preventing food waste, and portability, which makes them ideal for a variety of situations. At RAG Tailors, we use high-quality 600D polyester insulation with high-density insulated filling that ensures superior thermal efficiency. In addition, our bags are lightweight, easy to carry and can be customized with your company logo, making them excellent marketing tools.

RAG Tailors offers a wide range of insulated bags to suit different needs. We have everything from compact models ideal for carrying individual meals, insulated backpacks perfect for picnics and outdoor activities, to large capacity bags suitable for restaurants, events or large families. Our flexible coolers are available in different formats, including rectangular, cylindrical and bottle-specific bags. All models are made from high-quality materials, with waterproof and easily washable interiors, and can be complemented with insulated accessories such as dividers or additional pockets for custom organisation of the products to be transported.

At RAG Tailors, we offer a range of customisation options for cooler bags that transform a functional product into a powerful marketing tool. We offer three main methods: high-definition embroidery for a premium finish, digital printing for complex designs or photographs, and screen printing for simpler logos in large quantities. To request customisation, simply send us an email with the references of the desired product and the image to be applied, and you will receive a detailed quote. Our specialist consultancy service will help you adapt cooler bags to your company’s visual identity, with delivery times between 10 and 15 working days for custom orders.

The time it takes for insulated bags to maintain the temperature depends on a number of factors, including the quality of the insulation, environmental conditions and whether additional refrigerants are used. RAG Tailors insulated bags, manufactured with premium thermal insulation and waterproof interiors, keep food cold for approximately 4-6 hours under normal conditions. This time can be significantly extended (up to 12 hours) when combined with cold accumulators. For hot food, they can maintain the temperature for 2-4 hours. Our models with high-quality zips minimise heat exchange, ensuring greater efficiency in preserving the cold or heat chain, making them ideal for transporting meals or picnics.

The most durable cooler bags are made from high-density polyester (like the 600D we use at RAG Tailors), water-resistant nylon and PEVA or aluminium interiors. These materials combine tear resistance, efficient insulation and ease of cleaning. To keep your cooler bag in top condition, we recommend cleaning it after each use with a damp cloth and mild detergent, avoiding soaking it. Allow it to dry completely open before storing to prevent odours and mould. Avoid exposing the bag to extreme heat or direct sunlight for prolonged periods, as this can degrade its insulating properties. Our bags are designed to withstand frequent use, with reinforced stitching at high stress points.

Isothermal backpacks and traditional cooler bags differ mainly in their shape and functionality. Isothermal backpacks offer the advantage of being carried on your back, leaving your hands free, and are ideal for hiking, festivals or longer trips. They usually include multiple compartments for better organization and padded shoulder straps for greater comfort. Traditional cooler bags, on the other hand, are more compact, lightweight and easy to store when not in use. At RAG Tailors, both options are manufactured using the same high-quality insulating materials, ensuring equivalent thermal efficiency. The choice between the two mainly depends on the context of use and personal or professional preference.

Yes, at RAG Tailors we have a strong commitment to sustainability. Our range of eco-friendly cooler bags are made from sustainable materials such as recycled polyester and, in some models, natural jute combined with eco-friendly insulation. These sustainable cooler bags ensure the same thermal efficiency while reducing the environmental footprint. In addition, the superior durability of our products contributes to sustainability by reducing the need for frequent replacements. By choosing custom cooler bags from RAG Tailors, companies not only promote their brand, but also demonstrate their commitment to environmentally responsible practices, responding to the growing demand for thermal solutions that combine functionality and eco-friendliness.
