Adam Watts wrote a review of Icebreaker BodyFit 150-Ultralite Anatomica Relaxed Boxer With Fly - Men's on July 24, 2014
Familiarity: I've put it through the wringer
Fit: True to size
How it Fits:
I'm 5'10" 165lbs with a 33" waist. I wear a Medium in both styles from Icebreaker, The Everday Boxers are a little more snug around the waist while the Anatomica Relaxed Boxers are a little bit more relaxed. The Everyday Boxers are also more snug around the quads and thighs but never tight. For those coming from Exofficio's underwear like the Give-N-Go, the Anatomica Relaxed Boxers are the closest in fit. Fit wise, I prefer the Anatomica Relaxed Boxers over the Everyday Boxers because the Anatomica's slim fit but relaxed style makes you forget that you are even wearing underwear.
The 150gm fabric weight on the Anatomica Relaxed Boxers is perfect for summer hiking or climbing while being the ideal weight for everyday use. I wore the Anatomica Relaxed Boxers on a one day attempt to climb Mt. Daniel in the Cascades; 15+ miles, 5500 elevation gain. The weather for the eastern Snoqualmie valley that day was high's around the mid 90's making the long hike in and out pretty long. Once we hit the snow and higher elevation on Mt Daniel, the temperatures finally got more comfortable. While being stopped just shy of the summit, 1/3 mile and 400 feet elevation left, the Anatomica Relaxed Boxers kept me cool on the long approach and kept me comfortable and dry on the snow even after a few slushy glissades. Most amazingly, the underwear didn't smell at the end of the day!
If you're looking for an alternative to smelly synthetic underwear, Icebreaker's Anatomica Relaxed boxers and Everyday Boxers are some of the most comfortable ways to go!
Merino Wool is soft and stink free!y
Anatomica Relaxed Boxers are pricey at $44.99
