The Mountainsmith Zerk 40 ultralight backpack.

Review: Mountainsmith Zerk 40 Ultralight Backpack

Ultralight Backpack
Mountainsmith Zerk 40
$225, 40 liters/2,440 c.i., 1 lb. 13 oz./822g (including removable accessories)
One unisex size, fits torsos 16-19 inches

Within the rather exclusive category of ultralight backpacks weighing two pounds or less, one sees similarities, most commonly and conspicuously a frameless, roll-top design with large external pockets. The Mountainsmith Zerk 40 takes that template and juices it with some smart details and add-ons, tougher materials, and a touch of modularity while keeping it significantly under two pounds. That suited my needs quite well trekking hut to hut for six days on Iceland’s Laugavegur and Fimmvörðuháls trails—and I think much about the Zerk will also appeal to many ultralighters and thru-hikers.

Having backpacked numerous times through the Wind River Range on summer’s tail—and more than once been greeted with buckets of cold rain and wind for days or finding out that over a foot of snow fell the day after we got out—for my latest trip, I wanted to stick my feet in boots that can handle any unpleasant surprises. Still, I also didn’t want to feel like I was lifting a cement block with each step or like my feet spent each day in a hot yoga studio. Our five-day hike showed me the Scarpa Rush Mid GTX were a smart choice for what we encountered as well as what we might have encountered—and an all-around superior hiking boot.

The Biolite Headlamp 325.

Review: BioLite Headlamp 325

Rechargeable Ultralight Headlamp
BioLite Headlamp 325
$50, 1.8 oz./51g
backcountry.com

Look for an ultralight headlamp built for backcountry use that’s under two ounces and $40 or less and you’ll find very few choices—with the BioLite Headlamp 325 arguably the best among them. Then consider that it sports a basic but functional set of lighting modes, cranks out enough brightness and lasts long enough on a full charge for backpackers, dayhikers, trail runners, and other backcountry users, and this slim light will look pretty good to many people who log significant hours on the trail.

Backpackers seeking an ultralight, two-person tent with decent space and solid performance in a range of backcountry circumstances actually have several good choices these days—including six of my 10 picks for the best backpacking tents. And yet, there are many reasons they should consider the 2Lite from SlingFin, as I concluded by the first night of a long hike through the High Sierra in August, when strong gusts pounded our camp at nearly 10,000 feet all night.

Nemo Tensor Insulated Air Mattress.

Review: Nemo Tensor Insulated Air Mattress

Insulated Air Mattress
Nemo Tensor Insulated Air Mattress
$200, 13 oz. (regular mummy, not including stuff sack or pump bag)
Sizes: four sizes from 20×72 inches to 25×76 inches
backcountry.com

The search for the right backpacking air mattress tends to boil down to two competing objectives: finding a mat with the lowest possible weight without compromising on comfort. And different people will define comfort differently—thus affecting the weight of their air mat choice. But many backpackers and other users may find Nemo’s Tensor Insulated hits a sweet balance between those competing objectives, as I did sleeping on it for eight nights on a nearly 130-mile, August hike through the High Sierra, much of it on the John Muir Trail, and for four nights in early September in the Wind River Range.
