What Is TOG Rating? A Complete Guide for Baby Sleeping Bags

If you're sourcing or designing baby sleeping bags for your brand, TOG rating is the single most important product specification you need to understand. This guide explains what TOG means, how the scale works, and how to choose the right rating for your market.

What Does TOG Stand For?

TOG stands for Thermal Overall Grade — a unit of measurement used to indicate the thermal insulation of a fabric or product. The higher the TOG, the warmer the product.

In the context of baby sleeping bags, TOG rating tells parents (and buyers) exactly how warm a sleep bag is, so they can match it to the room temperature their baby sleeps in.

Why TOG Rating Matters for Your Brand

For brands and retailers, TOG rating is not just a product specification — it's a selling point and a safety communication tool. European markets in particular expect TOG ratings to be clearly labeled on all baby sleeping bags.

Getting the TOG right for your target market is critical. A brand selling into Scandinavian markets will need a heavier TOG range than one targeting Australian or Southeast Asian customers.

How We Manufacture to TOG Specification

At Babywear Lab, each TOG rating is achieved through a combination of fabric weight, knit structure, and fill material, working from your specification to hit the target TOG consistently across bulk production.

We manufacture TOG 0.5, 1.0, 2.5, and 3.5 sleeping bags in organic cotton and bamboo blends — available for OEM and ODM customization.
