Tog is a measure of thermal insulation. Lower tog duvets generally feel lighter and cooler, while higher tog duvets provide more warmth.

Common choices

4.5 tog is often chosen for warmer rooms or summer use, 10.5 tog is a popular all-round option, and 13.5 tog is generally selected when more warmth is wanted.

Room temperature and personal preference matter, so there is no single tog that is right for everyone. See our Duvet Tog Guide for more detail.
