Named after the notoriously steep and demanding trail up the north side of Mount Mansfield, the Hell Brook Hoodie is built for performance.
Cut and sewn in Vermont, the lightweight Polartec® Power Wool™ fabric features a next-to-skin Merino grid that is incredible for temperature regulation and moisture control during high-output activities. With layered construction, the quick-dry polyester outer offers more durability and showcases the benefits of both natural and synthetic fibers.
Perfect for warm days, cold weather exercise, and everything in between, you’ll get caught wearing this baselayer around the house not wanting to take it off.

Size Chart

This is a great hiking base layer for cool to kinda warm days. I love the Powerwool material as it’s great with moisture management and doesn’t get stinky as fast a pure synthetic base layer. The construction is good (better than some other cottage brands ) and the hood and thumb holes are well done
Sizing is a little challenging (as with all things ordered online) Believe the sizing info when they say it’s trim fit. If you have a broad chest or thick arms, go up a size from your measurements. I ended up passing my first shirt down to my wife and ordering another one a size larger
My kids love the hoodies and as of a few days ago my son hadn’t taken it off since Dec 25. Love the material and inner layer. Great color. Thanks so much.
Better than I even expected. Perfect fit, soft, comfy, versatile weight
This shirt is soft and beautifully made. I gave it 4 stars (and in truth, it’s my fault for not doing my research), because it’s only 31% merino wool. I thought for the price, its name, and custom made feel, it would be more Merino. Beautiful- just too much Polyester for me.
I thrash my hell brook hoodie on a daily basis while doing backcountry stone work on a trail crew. It’s held up to months of utter abuse and kept me warm and comfy during some real cold starts. My friends are jealous of how cool I look and always try to steal this unique item. Way better quality than a Melanzana. Thanks Thuja team
