What Doesn't Kill Us: how freezing water, extreme altitude, and environmental conditioning will renew our lost evolutionary strengthWe like to sit in air conditioned comfort, yet each year millions of ordinary people train in CrossFit boxes, compete in Tough Mudders, and challenge themselves in Spartan races. They are connecting with their environment and, whether they realise it or not, unlocking their hidden evolutionary potential. No one exemplifies this better than Wim Hof, whose remarkable ability to control his body temperature in extreme cold has sparked a whirlwind of

Love it!
Size: XX-Large, Color: Lavender/White Stripe
I am a cheapskate and try hard to find bargains, but i have no problem with paying this price for a quality piece of clothing! Loving the fit and especially the lavender color. Very classy wearing it fully buttoned or open collared. Looks and feels great!! I like this so much I bought the Aqua stripe and green stripe also!

Very solid option for comfort but the pattern of the shirt I received was off-putting
Size: Small, Color: Grey White Stripe
The shirt itself is great, sizing is spot on with an athletic tapered fit which I always prefer in a polo. The material is classic maelreg cotton feeling without the heaviness and water holding of typical cotton shirts. You can run in these polos, workout, go out to lunch or dinner, or simply sleep in these they are so comfortable. It's the patterns offered that made me return this and another I tried out. Colors are spot on with descriptions but the patters are small enough to play tricks on eyes, I received complaints from both my wife and daughter (separately) about the pattern hurting their eyes hence the 4 star instead of 5. Others may love the patter but know that it isn't as universally pleasing as more other shirts offered by this brand
