SaunaBoxers

SaunaBoxers: 100% Cotton Fertility Cooling Sauna Briefs

The SaunaBoxers: 100% Cotton Fertility Cooling Sauna Briefs are 100% cotton sauna briefs with an ergonomic ice pack that keeps things cool where it counts. You already do the work: you show up to the sauna and put in the sessions. Freeze the pack for at least 2 hours and slide it into the front pouch, where its pre-shaped form sits without shifting or bunching. An elastic-blend waistband finishes the athletic, supportive cut. They come in Small to XX-Large, in packs of 1, 3 or 6.

Scrotal temperature directly affects sperm quality, testosterone production, and overall reproductive health.
