IO Bio Track Jacket

www.io-bio.com, 9.5 ounces
Australia’s IO Bio has been behind the merino wool craze for years now, supplying a host of high-end outdoor brands with the thinnest, highest-quality versions of this all-natural miracle fabric.  But they stepped from behind the curtain about a short while back, and we’re glad they did.  Witness their signature Track Jacket, which gets just about everything right, from a loose, travel-friendly fit to a fashion-forward aesthetic (note the piped seams and the red-n-white logo badge on the left sleeve). And, as expected, performance isn’t sacrificed in the name of fashion. The wool is of the finest quality—thin, warm, and soft to the touch, with a 5 percent elastane for the right amount of stretch. A high collar seals in warmth, twin thumb loops add a bit more heat, and concealed zip hand pockets make room for mid-flight essentials (though some may wish they were positioned at an angle).  Wear this and you can fend off anything, from an over-pumped A/C on a cross-continental journey to a post-flight hike to hours-long urban exploration.
Comes in black and blue/grey
