Best praise vs top criticism for Mountain Hardwear Phantom
Best Praise
+9 pts“That is some review, considering you have yet to use them! I used a phantom MHW bag, with the treated down, and my partner had a mythic bag. I like the way that MHW make their bags and there was plenty of room, while the mythic looked a bit cramped. I also like the features of MHW bags but, with something like 3 pockets or places to put things, it seemed a bit too many bells and whistles. That might not matter but this will, bearing in mind that the MHW bag had been used for a week or so (neither of them were owned by me): The MHW bag had less loft and when it touched the end of the tent, the MHW bag got wetter sooner and remained wet longer, or damp, I should say. I was impressed with the Rab's ability to loft and remain dry but it was a new bag, which might have counted? I think the Rab stitching is just as good as the MHW stitching, for what it is worth. The mythic is too delicate, however, so I wouldn't want one myself.”
