Zenbivy Light: A quilt that pairs with a sheet to become a cozy bed

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.

Petzl Quark ice tools: An alpinist’s dream tool that handles it all

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.

Rab Muztag GTX Jacket: A worthy high-end shell that is light and durable

Alaskan climber Clint Helander generally prefers softshell jackets instead of hardshells when climbing and skiing, but the Rab Muztag GTX Jacket proved to be an exception. He writes, “I have always appreciated the ability of softshells to breathe and stretch while I methodically plod up steep snow slopes. In my mind, Gore-Tex jackets were still too heavy and restrictive in regard to movement…. I was happy to be proven wrong.” Five stars.

Lowa Alpine Expert GTX boots: Light, comfortable and sensitive

Whitney Clark used the women-specific Lowa Alpine Expert Gore-Tex boots in her snowy stomping grounds of the Sierra Nevada Range. She appreciated their lightness and comfort. The boots weren’t as warm as she would’ve liked, however, and on one occasion the supposedly waterproof boots soaked through while she was postholing and her feet got wet while her partner’s feet stayed dry. Four stars.

Valandre Troll jacket: As warm as a down coat can be

Scott Coldiron has a lot of experience when it comes to staying warm on frozen alpine routes. He’s been using the Valandre Troll jacket in Montana’s Cabinet Range and reports, “Simply put, this jacket lofts better under all conditions than other down jackets I’ve used, and the resulting warmth it creates is impressive.” It’s also more expensive, however, and it lacks a couple features he would’ve liked to have. Four stars.

Edelrid Bulletproof quickdraw: The burliness of steel with the lightness of aluminum

Alpinist Digital Editor tested the Edelrid Bulletproof quickdraw at Rifle Mountain Park, a world-famous sport crag where the volume of traffic frequently destroys carabiners. The Bulletproof showed hardly any signs of wear after hanging on one of the canyon’s most popular routes for four months, earning five stars. “Wait! This review is for Alpinist, what the hell is this sport climbing equipment doing here?” Franz writes. Read the article at Alpinist.com for his answer.

Unparallel Up Lace: A new company presents a new take on a familiar shoe

Chris Kalman checks out a little-known shoe company named Unparallel that makes climbing shoes eerily similar to the well-known designs made by Five Ten. He found that even Unparallel’s proprietary rubber is similar to the famous Stealth C4 rubber that Kalman has loved for many years. The fit and sizing of the Up Lace felt slightly different to him compared to the Anasazi, however. Four stars.

Lowa Rocket: climbing shoes made for heel/toe hooking

After extensive testing, Alpinist Digital Editor Derek Franz reports that the Lowa Rockets are best suited for toe- and heel-hooking, with a secure fit that ensures they won’t slide off the heel. Franz had trouble finding a size to fit his foot comfortably, however, and there is some bagginess over the top of the big toe. Three stars.

Mystery Ranch Scepter 50: a comfortable pack for hauling loads in the mountains

Whitney Clark tested the Mystery Ranch Scepter 50 backpack in Patagonia and in the Sierra Nevada Range. She reports that the pack provides a comfortable suspension system and is great for hauling loads. “I think that the Scepter 50 does really well if you have just the perfect amount of gear, but it does not adjust well to smaller or bigger loads,” she writes. Four stars.
