Ferrino Yukon Plus is a mummy-shaped sleeping bag ideal for trekking and camping, especially in summer. Its HTF-High Thermal Fiber Performance synthetic fiber padding gives it good thermal capacity: you can push it up to -10 °. The fibers of this particular fabric are hollow on the inside and this, combined with loose stitching that does not communicate between the inner ones and the external ones, make sure that the heat is not dispersed on the outside. If you have too much hot, however, Ferrino has thought of everything: the closure zipper is two-way just to adjust the internal temperature by opening the foot area. It is also possible to join two Yukon Plus (one right and one left) to create a double sleeping bag. Excellent then also for camping for several days. Then, once you get home, do not worry about washing it. The internal fiber is in fact washable, odorless and hypoallergenic! Ferrino Yukon Plus sleeping bag
