SAMBOB Microgrid Hoodie and Pants Review: Ultra-Cozy, Ultralight Layers Made Custom for the Trail
If you’re the type of hiker who geeks out over dialed-in layering systems and gets excited about custom colors and fits, the SAMBOB Microgrid Hoodie and Pants might just be your dream base layers. These midweight fleece layers are made in the U.S. using Polartec® Power Grid™ fabric, known for being lightweight, warm, and breathable. And they’re designed by and for hikers who actually live in this stuff.
Whether you’re layering up for a chilly thru-hike morning or bundling into camp clothes after a long day on trail, these pieces hit that perfect sweet spot of cozy, functional, and ultralight. And the best part? You can either go full custom with your colors and fit, or grab an off-the-shelf option that ships fast.
What Makes Them Special
The Microgrid Hoodie and Pants are made with Polartec® Power Grid™, a technical fleece designed with a gridded interior that traps heat without adding bulk. It’s warm, stretchy, fast-drying, and breathable—perfect for high-output cold-weather movement or lounging at camp.
The option to create totally custom pieces is next-level-cool.

Both pieces pack down small, making them perfect for ultralight backpackers, desert campers, alpine hikers, or anyone who wants layers that pull double duty from basecamp to trail.
I find that the grid fleece itself is soft, but not overly so. It hits a very nice balance between durable and comfortable. It doesn't shed like so many other grid fleeces on the market. As far as fit goes, the custom pieces are amazing as you get to choose how you'd like them to fit. Off the shelf pieces offer an array of sizing and fits, so be sure to read the descriptions to make sure you're getting what you want.

For my custom hoodie, I went with the wide size so it would feel extra comfy. I also selected the oversized hood choice so that my very big hair could fit comfortably under it. If you have a specific sizing in mind, you can enter your own sizing specs during the customizing process. Pretty neat!
