LD Mountain Centre Says:
Expedition 50+ Spray from Lifesystems is a powerful DEET based insect repellent that is effective on most biting insects and suitable for use in all but the most extreme areas of the world where the higher protection Expedition 100+ will be more effective. The spray gives long lasting protection which can be up to 10 hours but don't forget of course that this will be effected by humidity and perspiration.
Expedition 50+ Plus Spray Features:
Expedition 50+ Plus Insect Repellent spray is a dual action formula which combines natural pyrethroids with 50% DEET to provide a high level of protection against biting insects in all environments. The Natural Pyrethroids in Expedition 50+ Plus Insect Repellent spray act as a contact repellent so any insect actually landing on the skin will be deterred from biting. Each application of Expedition 50+ Plus will last for up to 10 hours although high humidity can lead to a slightly reduced time on the skin.
This repellent does what it promises.
I suggest it to every traveller.
