How to Measure for a Mammoth

The Mammoth is coming back in stock soon! Sign up for the email list for the most up to date information.

Everyone needs an heirloom woolen jacket. A jacket that can be proudly passed down through generations; a makeshift blanket, a cape, a cold weather companion. The goal of "The Mammoth" is simple; to be, and remain, unstoppable, to live up to its own name, to be the de facto best woolen jacket on the market. We hope The Mammoth can be yours. Let us introduce you two.

The Mammoth" at its thinnest point is 37-oz./LY of some of the finest wool available and, at it's thickest, a staggering 65-oz./LY. This jacket is so robustly built in fact, we debated on including a warning label with the care instructions.

V2 Updates:

  • Extended the interior back panel of wool all the way down to the bottom for even more warmth and protection.
  • Tightened the storm cuffs and switched them to Merino.
  • Increased our shoulder width by 1" (you can stick with your normal size, this was done for easier layering).
  • The cuffs are now buttoned to allow bulky mittens to be worn if needed.
  • Lil' patch update too.

Please, make sure to layer properly when venturing on daring excursions with "The Mammoth". It's beyond warm.

The Tale of The Mammoth

The Tale of The Mammoth is the first part of "The Lore Series". "The Lore Series" covers the lore of The Iron Snail far before The Prologue and Chapter Series began. Tales of the mightiest creatures in all universes will reside here, a necessary backstory to understand all of the Snail's powers.

The purchase of a Mammoth will also include:

A booklet of the tale (with blank pages to be used as a notebook) and a Mammoth patch.

The Hoxie Woolen Outer

"The Mammoth" is crafted from double-layered (front pockets & Wind Wall) 28-oz./LY 2x2 twill melton wool woven exclusively for The Iron Snail. We've dubbed this mighty fabric, Hoxie Wool. This edition of "The Mammoth" features a pine needle green, solid wool colorway. A color you'll be rather familiar with when walking around the New England wilderness (where the wool was spun into yarn and woven). 

This fantastically dense wool is designed to endure the harshest elements effortlessly while remaining breathable, fire-resistant, and anti-bacterial. Moreover, it provides insulation, even when wet.

Please note: These images are properly white-balanced, and there have been no color modifications made during editing. Depending on your monitor's calibration, the green may appear slightly different. We'd describe the color as a rich, dark pine needle—perhaps even a bit darker.

The Perfectly Suited Lining

Touching your skin is a 9-oz./LY faille woven worsted wool fabric, often used in fine suiting (to prevent itchiness and further block the wind). We chose this lining specifically to keep 'The Mammoth' 100% wool. This is a feature you will rarely ever find on another jacket. 

What are the benefits? Well, by not working with other fibers, we can modify the traditional layout of a woolen jacket to keep it sleek, yet extra warm (more on that later), while also ensuring it can be comfortably worn with just a t-shirt. 

The wool fiber used in the lining is finer than the fiber used in Hoxie Wool. Besides being softer against the skin, finer wools allow more air to be trapped in the yarns. This means that the liner, kept safe by the Hoxie Woolen outer, outperforms your average wool in terms of warmth-to-weight ratio.

No kidding!

The Wind Wall

Ah, 'Wind Wall Technology', something we're quite proud of! As mentioned earlier, we've chosen to craft this jacket entirely from 100% wool, giving us the flexibility to rearrange the typical layout (layers) of a wool jacket. Let us elaborate. We've meticulously placed the jacket's lining between the main body fabric and an interior chest and back plate made of wool. We gushingly refer to this as 'Wind Wall Technology.' The outermost layer of wool shields against the elements, the lining further stops the wind, and the interior wool plates (crafted from the outer fabric) act as unencumbered insulation. You could think of 'Wind Wall Technology' as an additional woolen blanket inside your jacket. Imagine an internal cape coat with an extra layer of warmth in between.

The Mighty Storm Cuff

Hidden inside of the sleeves are storm cuffs. Knit specially for us in Massachusetts. The cuffs are a midweight 1x1 ribbed Merino from the legendary Shaniko Wool Company, the first U.S. Farm Group to supply certified wool under the Responsible Wool Standard (RWS). The cuffs grip your wrists and create a gentle seal around them. A.k.a. these cuffs are sewn in to prevent wind, rain, and snow from entering your sleeves. Nobody likes that.

The Handy Action Clip

North of the storm cuffs and tucked into the left pocket is an action clip—a brass clip that allows you to hang your gloves, mittens, whistles, keys, or whatever else you may have from your jacket while you focus on other matters (like fending off all the compliments on your jacket). On the top left corner of the clip is an extra drilled hole meant for a keyring, so you can add any accessory you wish.

We've included the action clip with exploration in mind, but we're eager to see what you decide to snap on. 

We're particularly fond of those tiny jean keychains that you can get from many Japanese denim manufacturers.

On a more serious note, a neon orange whistle will probably come in handy one day if you're an explorer.

The Locking collar

Even further north of your action clip is the collar. A collar, of course, is something to be expected on any jacket and may not seem special at first. 

However, upon further inspection, this one is. Built to either lay flat or be popped up to protect the wearer's neck from the elements, the collar comes with an extra corozo nut button sewn on in order to fasten it closed when in stormy weather. These same corozo nut buttons are sewn throughout the jacket, securing pockets and the main placket.

Toss on a hat of any sorts and along with the locked collar, you can walk around with a covered and warm face, even sans scarf. 

The Hardiest Nut

Vegetable ivory— that's what they call it these days. Some refer to them as tagua buttons, while others prefer the term corozo nut buttons. 

Tagua nuts have been carved into figurines, coins, buttons, etc., for the better part of forever. But what exactly is it? According to Wikipedia, 

"Vegetable ivory or tagua nut is a product made from the very hard white endosperm of the seeds of certain palm trees."

Simply put, corozo nut buttons are individually unique, incredibly hard, lightweight, sustainable, and biodegradable. It's no wonder they were some of the most popular buttons used worldwide in the 1930s. 

Here's a fun fact: a tagua palm can take 15 years to mature, but once it does, it can produce tagua nuts for up to 100 years.

It’s a excellent coat, but has some flaws (NOT TESTED IN VERY COLD WEATHER)

I love where Micheal went with this coat, he’s keeping it more sustainable by using 100% wool, but I’d like to point out some things I wasn’t a fan of.
First the storm cuffs are still too lose, they don’t fit around my arms unless I have a longsleeve underneath, second the loop to hang the coat on a hook feels very fragile and I don’t trust it enough to use. Third, if you put almost anything in the lower two front pockets, or liner pockets the hand pockets get pretty uncomfortable even with some light glove liners. I think it’s like that too keep the shape of the jacket looking nice but it sacrifices comfort of the hand warmer pockets. I’m not much a fan of the action clip, it’s small and a bit hard to get key chains out when locked in. There were a lot of lose threads when it arrived which had me a little worried, but I think they were just ending for stitchings.
All that aside it’s a really good coat, I haven’t gotten to test it in anything below ~20 degrees, it’s wool is very comfortable and I’ve found it comfortable while wearing a tshirt (thanks to the what I believe to be merino sleeve liners). It also looks good, the color has for the last few weeks kept it shape, which I hope doesn’t change anytime soon. If you can afford it, get it, with all the garbage being produced, this jacket is far from that. I just hope the Iron Snail begins sales of glove, hats, and other wool clothing!

"The Mammoth: Warmth Worth the Weight?"

Material: 10 out of 10
Aesthetics: 10 out of 10
Durability: 10 out of 10
Fit and Comfort: 8 out of 10 (sleeves seem a little short)
Warmth: 7 out of 10 (Not as warm as I had hoped. I was outside in 30-degree temperatures with a 20-mile-an-hour wind and was freezing. You definitely need another layer or two beneath the jacket.
Overall Rating: 9 out of 10

I can’t imagine anyone being “on the fence” when considering a Mammoth. Especially if a colorway that you like comes along. Do not wait. Follow the suggestion to measure your favorite jacket to find your size, I did and I don’t regret it. Mine fits amazingly. I have two nephews, and if one moves north. He gets the Mammoth bequeathed to him. If they both do, they’ll have to figure out some kind of competition. A peak example of heirloom quality. Plus you get to support a passionate and knowledgeable artisan.

Incredible product!

It has taken me three hunts to finally land a Mammoth! I got one in Pine and absolutely love it. Excellent construction, design and close fit. Warm and stylish, I turn heads wherever I go. Love the big collar for this windy days. This Winter in Vermont the Mammoth has been well tested and delivers on all promises! I am hoping for a Leaf too…
In addition to the amazing coats I really enjoy the emails, the story and love how Michael works so hard, has so much passion, boundless energy and ideas. I wish him, Lyle and the brand all the success they desire. Bring on the shoes!

My wife can’t stop looking at me

I put on this jacket, and suddenly, I wasn't just a man, I was the man. The fit? Impeccable. The style? Effortless. The effect? My wife hasn't stopped staring at me since I buttoned it up. I caught her pretending to read a book, but I know she was just stealing glances. She says it's "just a jacket," but I saw the way she bit her lip.

I've been wearing this out in the single digit, never-ending Pennsylvanian winter and haven't felt the chill at all. Wind? Forget about it.

If you want warmth, comfort, and the undeniable attention of your significant other, this jacket is a must-buy. Just be prepared for the smoldering looks, and possibly some jealousy from her book club.
