Description

<p>The Firefly is the lightest sleeping bag in Mountain Equipment's Ultralight range. 252g of high-quality goose down provide optimal insulation and 550g of tare weight speak for themselves.</p><p>Mountain Equipment uses their proven and ultra-light Plasma™ outer and inner material for the Firefly. Inside, elastic EXL® seams ensure optimal insulation and freedom of movement. In the construction, the manufacturer relies on a slanted H-chamber, which combines the advantages of the trapezoidal chamber with the lightness of the classic box chamber.</p><p><span style="font-weight: bold;">Please note regarding the temperature specifications</span>: the values determined by the EN 13537 test give a good indication of the temperatures at which the sleeping bag will function.</p>
