Great riding shorts but need sizing info on the package.
Greagt riding shorts that breath well keeping you cooler in hot weather. My only complaint would be the lack of sizing on the package. Sure it says Large but it doesn't give a size range of waist sizes. The guy who helped me said he wore an XL and looked to only be maybe a 34 waist. I'm wear anything between a 36-38 and the XL is too lose on me. I really should have gotten a L.

PROS: Comfortable, Breathable

Comfortable, but cheaply made
After only one day (8-10 hrs) of wearing them, they are already pilling (fuzzy balls on surface). This was a disappointment, then again i think this is the store brand. So I should have expected it to be of poor quality.

THEY DO FEEL COOLER than cotton underwear.

PROS: Lightweight, Comfortable, Breathable

BEST USES: Racing, Street Riding, Long Rides

Performed as advertised
I bought these as an addition to my LD Riding shorts for use on a multiple day ride. The material is much thinner than the LD product but worked quite well in extreme heat and long riding days. The only complaint I have is that the waistband does not stay up; it rolls down after an hour or two making them somewhat uncomfortable at the waist.

PROS: Breathable, Lightweight, Comfortable

CONS: Waistband Rolls Down

On long adventure trips these are my only underwear!!
These are by far the best way to travel long distances off road.. They can be washed in camp and will be dry in about a hour.. The only option for going light weight on adventure trips.

Heat Out Shorts
I ride year round on various bikes on and off road, as well as snowmobile all winter. These shorts are wicked comfortable, breathable, wick away moisture, and are just down right comfortable. And you can't beat the price.....

WOW!! What a difference!
I ride my bike everyday. As a motorcycle commuter in Florida, heat is a real issue. These shorts have made a HUGE difference. I also work outside so I keep them on all day. They are lightweight and extremely comfortable. I will be purchasing a few shirts to add to my wardrobe. Best "hey I'll give these a try and see" purchase I've ever made and I highly recommend this line of products.

I love it!
I love this stuff and just bought more. I wear the shirt and the shorts. It's amazing for me, I sweat a lot, these products come in handy for me in almost every aspect of my life. I wear it every time I ride and as an undershirt to work if it's going to be a day full of manual labor. I wore it on a recent cruise to the Bahamas and it kept me cool and dry on the ship and on excursions (i.e. ATV's in Jamaica). They do run a tad tight so beware. A tight shirt is an XL for me, baggy XXL t shirt wise. I bought XXL and it's tight but comfortable. I believe the tightness helps it do it's job wicking away sweat.
