In addition to “Lajt” is “source wrap tank” one of the most common search terms people use to end up here, so thought that I would dedicate a blog post about this very good hydration system.

I had Source Wrap Tank when I made my season in Chamonix 2004/2005 which I bought in a shop there. This hydration system served me well during the season but was unfortunately lost.

To the Elbrus expedition I needed a hydration system and decided to once again buy a Wrap Tank. But that was easier said than done as this is remarkable unusual hydration system on the Swedish market, especially 2L variant that I currently cannot find at all. Finally I found a small online store that sold it but now will not remember which.

The fact of I am so happy with my Wrap Tank made Stefan, Victor, Mattias and my partner Emilie. So you can say that Wrap Tank is the hydration system Lajt use.

What is it that makes Source Wrap Tank that good?
That I value most is that both the bag and tubing is insulated so that it is okay to use even in the winter (if you blow back the water from the hose) but this also means that the system is protected and can handle rough conditions. My Wrap Tank was the only one of the three hydration system we had with us to Mount Elbrus that survived.

Another thing I like is the handle located on the insulation bag that the makes it very easy to fill both from a crane and the creek. The bag is also equipped with 4 buckles that make it possible to using a strap to make it into a backpack or hook it over other equipment.
