NEW CONTRAST STITCHING
NEW PATTERNING REMOVES IN-SEAM SEAM FOR ULTIMATE RIDING COMFORT
Did a quick 250mi ride to try these babies out right after buying them. They performed great and never experienced the typical issues associated with other garments. Don't have to be on the bike to appreciate them either. So comfortable I'm considering buying a pair for every day of the week! I will spare everyone by not uploading a photo.

These pants are great! They don't hold all that moisture and sweat like cotton. Fast drying and no thick seams. I wish they came in Nacho Libre colors but no, only ninja black. HiYaa!

I bought a couple pair of Aggressor briefs for track day riding and had a chance to try them last weekend. They were nicer and even more comfortable than I expected them to be. I washed them last night and they came through the wash just fine. I'm sure I'll be wearing these more often than I originally planned.
I would recommend them without reservation.

Never thought I'd be writing about underwear...
... But these are a notable exception. I've always been a cotton kind of guy except for paddling, cycling, and various other high-friction pursuits. At a friends suggestion I gave a pair of these a shot and now I won't wear anything else. They're ideal for layering and overall hind comfort. The difference in butt-comfort at the end of the longer days is profound in comparison to cotton. I'll be getting a few more pair for the longer hauls.
Construction, fit, comfort, and durability are typical for a KLIM product: Excellent.
In my opinion you cannot go wrong with these briefs as long as they come in your size.

Durable, comfortable, wicks, and dries overnight when hanging.
