Im new to this area, uaully i carry as much as i need or the routes ae planned with places to refill.....having spent some time looking at filters, tablets, pens etc, i am none the wiser as to which system is best, i like the idea of a filter but all of the ones i read reviews on appear to fail or leak or just not be upto it. Im planning to undertake some multi day trips and here in sweden there is an abundance of lakes and streams so it feels pointless lugging around so much extra weight in water. Any advice and help will be greatly received.
Cheers.
