Haglofs Zensor 1S

Haglofs Zensor 1S is a technically sophisticated fibre sleeping bag with great warmth-to-weight ratio. 1S means that this model is designed for one season (summer) conditions in the Nordic.

Zensor is available in two sizes. The smaller model is for persons up to 183cm tall and the large up to 200cm. 183cm model is available with left and right sided zippers, the 200cm only with left sided zipper. The zipper is two-way self locking YKK zipper. Two 183cm models (left and right) can be zipped together. Haglofs Zensor has a higher insulation rated foot section and bottom chamber to keep feet warmer. Head and foot section has specially designed fabric for waterproofness and fiber filled peak at forehead adds comfort. Thermal construction is based on the two layers on top and two layers in bottom.

This sleepping bag features also a three dimensional hood with easy and quick single hand adjustment. Zensor has also double baffles with improved zipguard. Some other often seen features are handy inside pocket for small items and hanging loops. The bag can be packed really nicely, the stuffsack is actually too large for this bag. Consider buying a smaller stuffsack if you like to pack your gear really tightly.

This bag is one of the lightest fibre-filled bags in this temperature range. Zensor 1S is one of the best choices for summer hikes, when temperatures at night don’t drop below 0°C. Details below are for the medium size (183cm) of the Zensor 1S. Zensor sleeping bags are quite easy to find at stores all over the world, especially at Europe because Haglofs is a Swedish outdoor gear manufacturer.

Really nice sleeping bag for the money. The size of the bag is quite small, so if possible test the bag before you buy it.

I don't recommend this product.
