Mountain Hardwear Micro Thermostatic Jacket

Active Junky gives Mountain Hardwear two toasty thumbs up for the Micro Thermostatic Insulated Jacket, a new addition to the line. At only 8 ounces, this ultralight insulator packs down to a delightfully manageable size, imitating the more expensive goose down that inspired its creation. Though not as warm as other more expensive/bulkier jackets, this versatile, synthetic alpine insulator is lighter than most comparable products on the market and was a tester favorite even as temps dropped into the 20s. From all-day forays into the Chilean backcountry and strolls through the rainy streets of Santiago to fall backpacking trips back home in Colorado, testers agree that the Micro Thermostatic Jacket is an excellent everyday insulator and a packable emergency layer.
