We used to use this net when were on holiday to India. It is large enough to cover the whole beg, you can't help but check that it is covering you all the way around, just in case a mosquito manages to get inside. This net has prevented me from getting bitten in the night, and has worked really well for my sister who is prone to being bitten. A night she forgot to use the net, she was covered in large red bites. Don't risk it, always use this or a mosquito coil when travelling to a tropical country.
