The 15° Arc Alpinist is a hoodless mummy - or zippered quilt - and besides confusion over its identity,

also a supremely adaptable piece of gear. Read more here

Alpinist Mummy with Gamut Synthetic Over-quilt


20° Alpinist down filled mummy bag, paired with the synthetic filled Climashield Apex 40° Gamut Quilt, creates a lightweight combination suitable for a wide range of conditions. 

Perhaps most important, the synthetic over-quilt protects the down from damp tent walls, or light rain and spray, as experienced under UL tarps. Condensing body moisture, so prevalent during winter adventures, settle on the easily dried over quilt instead of the down filled inner bag. 

The Alpinist and Gamut Quilt are designed to work as a unit, with the correct sizing relationship to maintain crucial loft. The strap placements and neck closure of the quilt work together with the mummy to make exit and entry simple. 

Total weight of the package pictured is 2lbs 13oz.

To further dial in specific needs, the Alpinist is offered in 20° and 40° versions, while the Gamut Quilt is available with 35°, 42° or 50° fill options. 

A 40°/42° setup combining the Alpinist and Gamut would create an incredibly versatile sleep system, suitable for anything save the depth of winter. All at weight of just over 2 lbs.

RDS Down Certification.

Nunatak adheres to the ethically advanced Responsible Down Standard. See this third party site for more info.

Only RDS-certified goose down is used in any product ordered from now on, whether specified with Hyper-Dry or pure down. 

There is no discernible difference in the quality between the old down and the responsibly harvested down. We have also not seen a need to increase prices as a result of this change.


Insulated Down Equipment for Trail Dogs!

We love backpacking with our dogs. We’re also pretty good at making quality down equipment.

We have now combined the two in the Nunatak Amarok, the Trail Dog Parka!

Thoughts on the practical application of UL gear

Ultralight backpacking - a moniker defining, among other things, the upper weight limit of one's base equipment (everything carried minus food and water). As an example, some sources state a UL kit must be below 10 lbs.

Backpacking Route Project: Moab West Side Monster Loop

For a while now I have toyed with the idea of a really big cross country loop starting and ending in or near Moab (where Nunatak HQ is located!). With inspiration from many shorter trips over the years, confirming water sources and sketchy passages, the pieces are now starting to fall in place. However there's still 'blank' spots on my map.
