I wear this type of boxer year round but if you need to be sold on a product wear these playing golf or running when its hot out. You instantly be sold on moisture wicking fabric for ever.

Pros:
Moisture Wicking*
Comfortable
Does not ride up.
Great for any type of outdoor activity.
Durable
Price

Cons:
I cant think of any.

*Moisture wicking fabric is a kind of fabric that is commonly used in workout clothing and sportswear because the material is designed to pull moisture away from the skin. As such, the fabric draws sweat and perspiration off of the skin and out to the exterior of the fabric. It is much easier for the moisture to evaporate on the surface of the fabric than when it is trapped between the garment and the skin. Cotton is an example of a fabric that traps moisture.

I have tried "dry" underwear before and it made no difference. Why are these different?
The difference is cotton. For example,&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Champion-Men-s-Double-Dry-Activefit-2-Pack-Boxer-Brief/dp/B001AY0WIK/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Champion Men's Double Dry Activefit 2-Pack Boxer Brief</a>&nbsp;are 95% cotton and a horrible choice for golf. The cooling effect on your body from sweating is produced when the sweat evaporates.  Cotton absorbs moisture and then holds it against your skin which does not allow the sweat to evaporate and cool your body, so you keep sweating and sweating. Synthetic materials such as spandex, mesh, polyester and Lycra wick the moisture away from your body in addition these materials don't absorb moisture (at least not even close to the extent that cotton does).
