Bought these for my teenage children for on holiday ( who tend to suffer sunburn even when wearing 50+ Sun lotion, very fair skin)
They are reported to be very comfortable, the children still wore sun lotion underneath when wearing the tops, they did not suffer any sunburn.
Cannot report onto the efficiency without sun cream underneath but the combination of top and cream did the job for us, no crying at night due to sunburn. My kids thought they were trendy and would recommend to anyone and I will purchase further in future when needs be.
Tops worn every day for 2 weeks, no bobbling or fading yet, hopefully will get many holiday spells before needing to purchase again.
