Reviewer Drew Thayer notes, "The Ultamid 4 is currently the lightest option for a spacious, four-person shelter that can adapt to just about any conditions.... It's a great shelter for backcountry pursuits where versatility and light weight are necessary. And it's made right here in the USA."

Climber and guidebook author Stewart M. Green reviews the Mammut Belay Chain: "Unlike the personal anchor systems made by Metolius, Sterling and Black Diamond that use six links of the same size, the Mammut chain links are of two different sizes. The first three links are 11 inches long, and the last three links are 3.5 inches long. These differing lengths allow you to attach to different anchors at a belay station easily and quickly."
