V.I.B. 600 is a medium weight down filled sleeping bag for year round outdoor use. The V.I.B. 600 is part of the very popular V.I.B. range of Yeti bags with the finest possible European goose down filling wrapped in a casing with a wealth of technical details. The V.I.B. 600 has a full down collar, full zipper and the S-Box construction. The outer fabric is breathable and the inside lining has the V.I.B. series trademark signal colour. V.I.B. 600 offers nearly the same insulation as our more extreme series and can be used in any performance context where weight and pack size is an issue.
