Nunatak Arc UL: Weight, Price and Alternatives
The Nunatak Arc UL is sold direct by Nunatak and is not available on Amazon, so check the exact specification for the version you order.
The Nunatak Arc UL is our expert tier pick in quilts . One of the original quilt makers, still building each one to order with a long list of fabric and fill choices. Lead times are long and the fit is as close to bespoke as this category gets.
What is the Nunatak Arc UL actually good at?
One of the original quilt makers, still building each one to order with a long list of fabric and fill choices. Lead times are long and the fit is as close to bespoke as this category gets.
Best for: People who already know exactly what they want and cannot find it off a shelf.
A quilt deletes the insulation you were flattening underneath you anyway, plus the hood and the zip, which is where its weight saving comes from. Quilts are a cottage category: nearly every maker builds to order and sells direct, which is why they fit better than off the shelf bags and why almost none of them appear on Amazon.
Why is there no single published weight?
A blank specification on this page is deliberate rather than a gap. There are two reasons an item on this site carries no single weight, and both of them are cases where quoting one number would be inventing precision that does not exist.
The first is made to order cottage gear. Quilts and several packs from small manufacturers are built individually, and the finished weight depends on the temperature rating, the fill power, the length, the width, the shell fabric and the options you choose. A 20 degree quilt in 950 fill down at a regular length weighs meaningfully less than the same quilt in 850 fill at a long length, and both are the same product name. The maker publishes a weight against a specific configuration on the order page, and that is the number to use once you have chosen yours.
The second is footwear and apparel sold by size. A published pair weight is measured at one reference size, usually a men's nine or a women's seven, and yours is probably not that. Shoes gain and lose roughly half an ounce per half size, which is enough to make a cross-brand comparison at the ounce level meaningless. It is also why most trail shoes have no single retail listing to link to: the listing is per size and per colour.
In both cases the honest thing is to check the specification for the exact configuration you are ordering, then weigh it yourself when it arrives and put the real number into the gear list builder. That is worth doing for everything on a gear list, not just for this item, because published figures run optimistic often enough that a thirty item list can drift by a pound.
How does it compare with the rest of the quilts?
Every item below has been verified against the retailer listing, and every weight is the manufacturer's published figure for the configuration named. Sorted lightest first, so the trade between weight and everything else is visible in one pass.
| Model | Published weight | Listed price | Tier | Where to buy |
|---|---|---|---|---|
| Nunatak Arc UL | Varies | Varies | Expert | Nunatak direct |
| Enlightened Equipment Revelation 20 | 1 lb 5 oz | About $340 | Intermediate | Enlightened Equipment direct |
| Hammock Gear Economy Burrow | Varies | Varies | Beginner | Hammock Gear direct |
| Katabatic Gear Palisade 30 | Varies | Varies | Expert | Katabatic Gear direct |
Why does this quilt have no EN or ISO rating?
Cottage quilt makers build to order and most do not pay for EN 13537 or ISO 23537 laboratory testing, so a quilt rating is usually the maker's own figure rather than a certified one. Treat it the way you would treat a certified limit rating, which is to say as a survival number rather than a comfort one, and plan for comfortable sleep roughly 10 to 15 degrees Fahrenheit above it. Drafts are the failure mode that ratings never capture: a quilt that is not sealed to the pad leaks warm air every time you move, and no fill weight fixes that.
Who should skip it?
Anyone buying their first version of this item. Expert tier gear is specialised, and specialised means it is better at a narrower set of conditions rather than better at everything. Buying it first usually means discovering an expensive preference rather than confirming one.
Going lighter must not mean going unprepared. Shelter adequate to the actual conditions, insulation, rain protection, water treatment and a way to call for help are fixed costs on any list. If a lighter version of this item means cutting into one of those, it is the wrong purchase however good the spec sheet looks. You are responsible for what you walk into, and the forecast is not the conditions.

Frequently asked questions
How much does the Nunatak Arc UL weigh?
The manufacturer does not publish a single weight for this item in a form we can quote reliably, usually because it varies with the size or configuration you order. Check the specification on the retailer page for the exact version you are buying, and weigh it yourself once it arrives before you put a number into a gear list.
Is the Nunatak Arc UL worth the money?
One of the original quilt makers, still building each one to order with a long list of fabric and fill choices. Lead times are long and the fit is as close to bespoke as this category gets. Pricing on this one moves with configuration and retailer, so confirm on the product page rather than trusting a figure here.
Where can you buy the Nunatak Arc UL?
Nunatak sells this direct and it is genuinely not available on Amazon. That is normal for cottage ultralight brands, which build to order and sell through their own storefront. The link on this page goes to the manufacturer and earns us nothing, which is exactly why we are comfortable recommending it.
What does the Nunatak Arc UL compete against?
On the same shelf: Hammock Gear Economy Burrow, Enlightened Equipment Revelation 20, Katabatic Gear Palisade 30. The comparison table on this page lines them up by published weight and price so the trade is visible rather than argued. Our full ranking of the category, split into beginner, intermediate and expert tiers, is in the roundup linked below.
Are the weights on this page measured or published?
Published. We compare manufacturer specifications and verified owner reviews, and we do not test gear in person or run a gear lab. Manufacturer weights are usually taken from the lightest size, without stuff sacks, stakes or guylines, so a real-world figure is often an ounce or two heavier. Weigh your own kit and put the real numbers into the gear list builder.
How we choose: we compare published manufacturer specifications, listed weights, and verified owner reviews across retailers. We do not test gear in person, and every weight quoted here is the manufacturer's figure unless we say otherwise, so weigh your own kit before you trust a total. Going lighter also means carrying less margin, so treat insulation, navigation, water treatment and an emergency plan as fixed costs rather than places to save grams.
