    Great undies

    John in CO

    Like Wearing Nothing At All

    Super comfortable and cool when it's hot. I wear knee braces under my pants and these work perfectly to keep my legs and knees comfy.

  • Leatt 3DF AirFit Lite Shoulder Tee

    Jacob in AZ

    I like it!

    So far I really like this thing! The material is pretty awesome. Stretchy mesh so it’s really breathable. I’ll see how it does this summer in the Arizona heat. Shoulder protection is great since I hate bulky strap ons or the ones attached to roost guards . ( I haven’t crashed with it on yet though) Pretty spendy but the quality is good. Order one or two sizes up. It fits like a compression shirt. I wear a large t-shirt. (5’11”) 200lbs. I Ordered an xl and it still fits very snug.

  • KTM Padded Riding Shorts

    Ronald Dirk in NJ

    Worth the cash to save your butt.

    Good fit good padding a little warm in summer. I would only wear one thin layer under them if anything at all. Otherwise they move a little bit too much.

  • Fly Racing Barricade Compression Shorts

    Peter in NV

    Fit a bit narrow

    I'm 5'8 175lbs with an athletic build. I wear a size medium in regular underwear. At first I purchased a medium and it was real tight, uncomfortably tight. its the way the product is made, it is a very narrow fit very rectangle like. I exchanged for a large and although it fits better I now have to wear it hiked up my torso so the waist band isnt too loose.

  • Leatt 3DF 4.0 Impact Shorts

    Jason in CO

    comfortable protection

    Ive been a cyclist for decades so shorts like this are not new to me. The pads form to your body and work great under riding pants(Klim Dakar for me). These are very comfortable for great protection.
