Backpacking Light Beartooth Merino Wool Hoody

Full-featured insulating top with hood, zip, and thumb loops.

A very small batch of Beartooth Merino Wool Hoodies were uncovered in our storage shed and are now available for a short time.

Beartooth Merino Wool Hoody

Inspired by the need for a single, functional, highly versatile garment that minimized the need for layering changes during the Arctic 1000 expedition, the Beartooth Merino Wool Hoody finally blends technical design and styling with the right fabric for the job.

This piece provides warmth, comfort, and functionality. Period. Complete with a temperature regulating neck zipper, a balaclava-style warmth-retaining hood, and thumb loops that keep the wristcuffs in place for hand warmth, the Beartooth Merino Wool Hoody will quickly become one of the most versatile pieces of clothing in your system.

Notes from the Field

A prototype Beartooth Merino Hoody has been in field testing for nearly a year and response to its performance has been excellent. The hoody prototype has been tested in all typical (and some atypical) temperature ranges of the Rocky Mountains from summer highs to winter lows. As a stand-alone piece in warmer temps, the zipper at the neck and the hood allow for a wide range of thermal regulation. Used in conjunction with other garments, the Beartooth Merino Hoody will boost warmth while allowing the option for ventilation.

The comfort of the garment against the skin is superb - the Beartooth Merino Wool Hoody is made with 18.5 micron superfine merino from New Zealand. For those who haven't had the chance to try these, merino wool, by its nature, is brushed to be smooth and velvety - not scratchy like your grandad's wool sweater.

In terms of sturdiness, the Beartooth Merino Hoody is designed to last. It is made from a slightly heavier (150 g/m2) fabric than Backpacking Light's Merino UL series; in addition, the Beartooth collection has serged seams, mechanical stretch, and a finished edge around the cuffs and face to make this piece a garment that is durable enough to be worn alone or as a baselayer.

Clothing Ensembles and Layering

Backpacking Light is devoted to helping you achieve the perfect clothing system. The Beartooth Merino Hoody has been designed to optimize your clothing system by providing maximum performance for multiple purposes while minimizing the volume of gear carried. The balaclava hood on the garment provides protection from sun, wind, and cold, allowing you to consider leaving various hats off your gear list. The thumb loops on the garment extend the warmth around the palms of your hands, eliminating other pieces. When Ryan Jordan wore the first iteration of this garment on the Arctic 1000, he left his hat and gloves at home and relied solely on the hoody's functionality to make up for it. This strategy worked so well that it remains Ryan's primary strategy for all but the worst conditions between Memorial Day and Labor Day.

The Beartooth Merino Hoody pairs excellently with other parts of the Backpacking Light clothing system. For cold weather, pair the hoody with the UL Merino Long John Pant and the Cocoon insulated clothing line. For summer, take the hoody for up top and your Thorofare Trekking Pants for down below. However you pair the items up, the Beartooth Merino Wool Hoody will provide solid, all around performance in thermoregulation, comfort, and adaptability to your environment.

Consumer Review

Having moved to Central Oregon from southern California, I knew I would need to beef up my cold weather clothing.

Why a hoody? There are several reasons for my picking a hooded base layer. They predominantly center around convenience and flexibility. Effectiveness of the garment as a base layer is a given. While hiking yesterday using the BPL merino hoody, I was able to benefit from neck protection, venting, and partial or full head coverage whenever I needed it. Paired with my eVent shell, I was able to instantly regulate my heat over many varying conditions. It was 4º F plus some wind, so I would vacillate between being chilled by a breeze, then starting to get too warm when ascending. Simple, small, and immediate hoody adjustments meant I did not break a sweat nor get too cold. This is a huge benefit for me when winter hiking - particularly over my previous zip-T and balaclava system. Core temp regulation could end up being a life or death issue and, in the past, having to stop and remove or put on my hat or balaclava each time the conditions changed did not often happen. I'd usually let myself get cold or sweaty, and the merino hoody I got from you eliminated all of those potentially dangerous issues.

Why the BPL merino hoody? I seriously considered a Patagonia R1 zip hoody instead of the BPL merino hoody. I read everything I could find about both and even went to a Patagonia store to get a feel for their hoody. The main reasons I choose the BPL merino hoody were the fabric and the garment thickness. The merino wool hoody would lay next to my skin more effectively than the R1 fabric in my opinion - allowing for less cold air to be trapped next to my skin. The bigger reason though is that for me, the thinner material used in the BPL hoody offered me a garment that would offer a much wider range of applicable use. The thicker Patagonia fabric would render me much too hot very quickly after beginning a hike, and therefore would only really be effective on hikes with sustained temps below 0º F. With the thinner merino hoody I am able to use it as a base layer in very cold conditions but also moderately cold and even slightly warm conditions. Given this, I did worry going in that the fabric would be a bit too thin to effectively keep me warm in cold conditions - especially my head. I was proven wrong on yesterday's 4º hike. The effectiveness of the merino wool occasionally coupled with a shell hood was fantastic... Dare I say perfect?
