Alpinist digital editor Derek Franz has been using the Zenbivy Light bed system for the past year. As a guy who prefers to avoid the constriction of mummy sleeping bags, he sleeps comfortably with the Zenbivy in a variety of environments. His only critique is that the setup can be a little tedious. Four stars.

Alpinist Tad McCrea has been using the latest model of the Petzl Quark ice tools for the past year. As a longtime user of the earlier models, he reports that the tools continue to live up to his expectations. He writes, "If you already have a set of the last Quarks, maybe you don't need to jump to an upgrade just yet, but if you want a set of axes that handle it all, and are in the market for an alpinist's dream tool, look no further." 4.5 stars.
