Review: Sleeping Bag - Healthguard

I used over 3 mth on the Bibbulmun track WA end to end. Through the last weeks of the walk, we found ourselves overnighting in the open huts with masses of mosquitoes. I had no net and I slept in the treated sleeping bag, whilst the others slept under nets. Most nights it was zipped up, but sometimes it was too hot so I had it open. I was never bitten. I was told the bag was impregnated with a 'synthetic pyrethroid' which certainly seems to work. D.Clegg
