Select styles, modeled by Zink’s other muscled muse Diego Miguel, are now available for pre-sale on the label’s website. The white brief worn by Boselli in new promo shots is the Charlie classic brief — a staple we’ve come to know and love, and will remain available long after the 2016 collection is gone, thank god.

Now that the school year is back in full swing, we assume Boselli is at the head of class once again. In August, the part-time underwear model and engineer talked a bit about his summer job in a behind-the-scenes video for Canadian retailer Simons.

Perfection in human form.
