  • “The spec says the length is 78", fit to 6'. 78" is much longer than 6'. Will it fit a 6'2" person?”
    Asked by Lori from NJ on 4/22/2018 8:41:27 PM
    • You probably could fit 6'2", but it is only rated to 6' comfortably.

  • “In order to zip 2 of these bags together one would need a left and right handed zipper, correct?”
    Asked by Eric from OH on 4/17/2018 9:41:55 AM
    • Yes, to zip compatible mummy bags together they need to be opposite zips.

About Mountain Hardwear

Starting back in 1993, a small group of outdoor industry mavericks broke away from the pack to follow a less-traveled path. From the very beginning, the primary goal of Mountain Hardwear was to create an outdoor gear brand with a sharp focus on technology-driven design, superior performance and hardcore reliability. The result of this function-first mentality has been an array of incredible Mountain Hardwear jackets, clothing, tents, backpacks, sleeping bags and accessories. Today, after more than two decades of industry-leading innovation, Mountain Hardwear continues to set new benchmarks for dependability in the toughest conditions on the planet.
