Our best-selling and award-winning Alta range has been redesigned with a new fit, new fabrics and the warmth-to-weight efficiency has been improved by 20%. We can offer a bag for any climate, with temperature ratings between T-Limit +8 down to T-LIM -25 and a wide range of fit with standard, long, extra long and lady versions. There is also our unique lady-fit that incorporates a shaped internal collar, additional width and extra down fill in the foot area for an even more comfortable night’s sleep.
The biggest design change is the shape. If a sleeping bag fits well, it will keep you warm. We translated the fit of our Rago series into a synthetic bag using the same high-performance water-repellent Helsport Thermoguard fill and adjusting the shape of the shoulders and hood to minimise heat loss.
The main zip has been redesigned to reduce snagging and the drawcord material changed and improved for ease of use. The design around the hood opening has been completely changed with an internal drawcord and a soft, insulated face muff added for greater comfort while you sleep.
Underneath, we have kept the same no-slide base to make sure you wake up in the same place where you went to sleep. There is a handy pillow pocket under the hood for extra clothes to be turned into a pillow, and reflective tabs at the foot for a final touch.
The compression sac has been updated with new fabric, double-ended compression fins and low-profile buckles to avoid snagging. The lid opening has been highlighted with a strip of reflective piping for ease of use.
