Menstrual flows vary depending upon whether you are lying down, standing or sitting. Bodyform Ultra Goodnight has an extra absorbent system that prevents leakage giving confidence during your period. The Bodyform Goodnight towel has wings to keep it in place so even if you toss and turn in your sleep the Bodyform Goodnight towel will remain in place. Bodyform sanitary towels contain a layer of super absorbent material called efficapt. Made of compressed cellulose, a natural and renewable forestry product, efficapt has incredible absorption properties for security during your period. The efficapt core also has an unsurpassed ability to spread fluid over the entire super absorbent surface to prevent it from collecting in one place. This allows Bodyform sanitary towels to utilise every tiny fibre to keep you fresh and dry even at the heavier points of your period.
