A surviapure waterbottle with internal filter has got to be my favourite bit of kit now. I used to carry all my water but one of these water bottles mean that all I'm carrying is a litre now! It's the best £40 I've spent in a long time.
I recently invested on a Lifestraw as well. Purifies the water straight from source. Below is the link:

Best regards,
Hi bandel4 what do you pay for yours there seems a big jump from £3.35 on Lifestraw site to £20 each on uk e-bay. I'd certainly use one on the move if the price was right My wife has to be careful with Iodine though as she suffers with hypothyroidism and takes thyroxine tablets. At base camp though it's boil it.
