Choosing the right TOG rating keeps you comfortable on all types of summer nights whether they are hot and humid or cool in air-conditioned rooms. Below is a useful research-backed guide to help you pick the best summer quilt.
1.Understanding TOG
TOG (Thermal Overall Grade) measures a quilt's heat retention ability.
Higher TOG means better heat retention.
Lower TOG means better breathability and a cooler feel.
For reference many people choose quilts with a TOG of 2.5 or lower in summer.
People who sleep hot may prefer a TOG between 1.0 and 2.0.
Note TOG is a standard for quilts and duvets. The same TOG can feel different based on fabric fill weight and room conditions.
2.Factors affecting perceived warmth
Bedroom temperature the recommended optimal range is usually 60–67°F (15–19°C). A warmer room requires a lower TOG.
Humidity and airflow high humidity can make you feel hotter good airflow provides relief.
Bedding layers using sheets blankets or multiple layers changes overall warmth.
Sleep habits some people always sleep hot or cold regardless of season.
Quilt construction fill types like down/feather or synthetic and quilt baffles affect warmth. A thin cotton cover with dense fill may feel warmer than a lighter option.
3.Recommended TOG ranges for summer
Hot sleepers or very warm climates 0.5–1.5 TOG
Moderate warmth (typical summer nights well-ventilated rooms) 1.5–2.5 TOG
Air-conditioned rooms or cooler summer nights (if you often feel cold while sleeping) 2.0–3.0 TOG
4.Choosing by scenario
Scenario A Hot and humid nights
Choose a quilt with a TOG of 0.5–1.0.
Consider materials like lightweight cotton or bamboo covers with breathable low-fill fiber or down alternative.
Pair with breathable sheets (percale or sateen with good airflow).
Scenario B Comfortable with ceiling fans or moderate AC
1.5–2.0 TOG is a flexible choice.
Look for a quilt that breathes well and wicks moisture to prevent dampness.
Scenario C Air-conditioned rooms or cooler summer evenings
2.0–2.5 TOG provides enough warmth without overheating.
Choose a quilt with slightly denser fill or high-quality down alternative that still allows air circulation.
Scenario D You generally sleep hot
Try layering use a light TOG quilt (e.g., 1.0) with a lightweight blanket you can adjust during the night.
5.Materials and construction affecting warmth
Fill power and type higher fill power usually means more warmth per ounce but in thin quilts synthetic fills can feel cooler and more breathable than heavy down.
Cover fabric cotton covers are breathable cotton blends work well too. Synthetics may wick moisture better but can trap heat if not breathable.
Baffle design box or offset baffles help maintain even fill distribution and prevent cold spots.
Weight and loft a thinner loft with well-distributed fill generally feels cooler.
6.Practical tips for trial and fit
Start with 1.5–2.0 TOG and adjust based on comfort after a few nights.
Consider layering use a lighter quilt plus a breathable throw you can add if needed.
Check temperature cues wake up sweating or too cold adjust accordingly. Your body's signals are the best guide.
Care and maintenance follow washing instructions to preserve loft and breathability. Proper care keeps the quilt comfortable longer.
7.Care tips to maintain comfort
Washing use mild detergent suitable for the fill type avoid harsh chemicals.
Drying ensure thorough drying to prevent odor and mildew add dryer balls to restore loft.
Storage store in a breathable bag not a compressed vacuum bag to preserve loft.
8.Quick decision checklist
Is the room usually hot or cool after sunset?
Do you generally sleep hot or cold?
Do you use air conditioning or fans?
What materials do you prefer for feel and breathability?
Are you open to layering for flexibility?
