Advanced Mountain Kit

We Just Tried TNF’s Most ‘Advanced Mountaineering Kit’ Yet

The North Face introduced the Advanced Mountaineering Kit at the Outdoor Retailer show this winter, and it blew our minds. We got a first look at this pinnacle equipment package on a ski tour near Aspen, Colorado.

From new fabric technologies to a completely new way to design high-altitude mountaineering footwear, the Advanced Mountain Kit (AMK) from The North Face is among the most refined equipment lines we’ve seen.

At its simplest, the kit is an apparel and equipment line for high-altitude mountaineering’s elite. But that simplification glosses over 2 years of research and development. And it overlooks the integration that sees each item as critical in specific situations on the mountain.

Oh, and the whole kit costs about $15,000! That includes a tent, sleeping bag, footwear, and a suite of apparel and outerwear made for any peak on the planet.

GearJunkie founder Stephen Regenold and I traveled to Aspen, Colorado, to meet with Scott Mellin, VP of Global Mountain Sports at The North Face, and guide Nate Rowland for a test of the TNF AMK line. It was the first review by anyone outside the company. Read on for our initial impressions.

The North Face AMK: First Look Review

IMG_1290

It’s about 2 p.m. on a Saturday, and the sun is powerful for the winter in Colorado. I’m climbing hand-over-foot up a steep summit ridge above 12,000 feet. In front of me, Regenold, Mellin, and Rowland balance their way through post-hole steps and loose rock as we near the summit.

Even though temps aren’t below freezing, Regenold wears an insulated puffy stuffed with 1,000-fill down. It’s the most versatile puffy jacket we’ve seen (more on this below). I have on a heavy fleece layer set and shell pants.

In most situations, I’d call both of us overdressed. But this is gear testing and a perfect way to get a feel for some of the claims surrounding the apparel and outerwear of the AMK.

Heading Up the Mountain

AMK L2
AMK L2 midlayers

I donned several pieces of apparel for the skin track. Starting closest to the skin, I wore the AMK L2 Pullover and Pant. These fleecy, midlayer-style garments felt good on the skin and offered my main insulation for a temperate mountain day. At $400 and $300, respectively, these are likely the most expensive midlayers on the planet.

What do you get for that price? The North Face packs in some wild tech, including full-loop fabric construction made with octagonal-shaped yarns with hollow cross-sections. The point is to provide high thermal performance at a light weight.

I found the layer, which I wore against my skin, soft and comfortable. TNF designed it to quickly pull moisture to the outside of the garment and dry super fast. And I never noticed any moisture buildup from sweat (which I did a lot due to the warm temps).

We pressed TNF about the pricing. The company explained that products in the Advanced Mountain Kit use expensive manufacturing and the most premium fabrics and trims “to ensure maximum performance at minimum weight.” The limited development also means fewer efficiencies and cost benefits of bulk purchasing, adding to the overall cost of each piece.

Indeed, from the $400 L2 Pullover top on up, each piece is something of a “concept car” for the company. TNF was not going for the mass market, and price control is not the object. The fabrics and designs unveiled here push boundaries and offer a new take on what mountaineering apparel can be.

Mellin described a shift over the past few years. Mountaineers move faster in the high peaks, and in some regions, glaciers are receding and temps are warmer. Better gear, better training, and even niche products like hypoxic tents have changed the paradigm. The AMK line is a response to the new variables of the climbing world.

On the peak near Aspen, for shells, I wore the Summit AMK L5 FUTURELIGHT Jacket and Pant. They protected against wind and moisture, and both were highly air-permeable, breathable, and seam-sealed. A special make of the FUTURELIGHT fabric with more mechanical stretch was manufactured for these pieces.

They come in at a premium price of $1,000 for the jacket and $750 for the pant. The kit worked flawlessly in the mild conditions of the day. Skinning uphill, I alternated between wearing the L2 top alone and with the L5 shell. I wore the shell pants and L2 midlayer pants the whole way up. I stayed dry all day despite sweat and exertion in the sun.

We were on the mountain for about 4 hours. While this was a brief test for a kit meant for major mountain assents, our initial feedback is that the TNF AMK is indeed a dialed kit. Fit, function, and breathability are exceptional. Nothing was cumbersome, and the kit felt extremely light considering the apparel is for big mountains and serious ascents.

AMK L3 Pullover Hoodie: The Puffy Refined

Regenold opted to wear a next-level insulating piece for most of the uphill skin. The Summit AMK L3 Pullover Hoodie is not a normal puffy. It’s a lightweight insulated jacket unlike anything we’ve seen. Insulation comes from premium, 1,000-fill goose down in horizontal baffles. Its thin ripstop fabric has a metalized finish, adding thermal performance by reflecting body heat.

It gets stranger from there. The jacket’s fit and feel fall between a belay jacket and a windbreaker. Then there’s the 50/50 Down technology designed with gaps between each down tube, allowing for airflow via the semi-permeable fabric.

Regenold wore the $1,000 piece almost all day. He never overheated; the piece did its job regulating throughout a range of temperature and heart-rate zones.

Onto the Summit Ridge

We boot-packed the last few hundred yards to tag the summit. Then we transitioned to downhill mode and prepped for a steep descent to the valley floor. I took a couple falls on the way down, the variable snow snagging my edge. Mellin sliced ahead, dropping out of sight in the trees.

An hour later, we were back at the car, a steep and deep descent under our belts and smiles all around. Regenold looked down at his jacket with disbelief.

“I forgot I was wearing this puffy!” he exclaimed. Mellin nodded in agreement, noting that when the gear is right, you forget it exists.

And in many ways, our first experience with the AMK reflected success in that goal.

The North Face set a high bar with the AMK. It’s a highly focused product line for a niche of high-performing mountain athletes. And it carries a hefty price tag. But the fabrics, function, and the new approaches it offers to mountaineers make it unique in the industry.

Below are details of the AMK products as provided by The North Face. Please note that GearJunkie has not yet tested most of the line. In addition, some of these products will only be available for professional TNF athletes.

For the rest of us, the AMK line comes to market this spring. Check out more details in anticipation of the launch here.
