Goodproduct
I bought the shirt and pants at the same time. The shirt I had to send back s it fit small. The pants were spot on following the size chart. A little pricy, but they performed as advertised after taken several rides that ranged in temps from low 40's to upper 70's.

Go up one size!
I bought a Large and they fit like a Medium. Also, the bottom of the legs are loose, not snug so I hope when I wear them for skiing they do not bunch up and hurt my shin/ankle on the tongue of the ski boot. For moto boots it is only an inconvenience to put the socks on first, not over the Klim pants.

I would return for a larger size but with shipping it isn't worth the trouble. Hope this review helps you.

3XL (?). Really?
Big Guys need not apply. These ( just like the aggressor shirt run VERY VERY small. Now grant it, I am not use to wearing spandex type clothing. But when looking at the size chart it says 3XL will fit up to 50"+ waist. No way in hell. Better quality than cycle gear stuff for sure. Just understand if you want to breath, go up at least two sizes plus.

Best base layer value ever
I've tried pretty much everything available, and these are my favorite base layer by a considerable margin. And, at $25, they're the best deal ever. Super comfy, easy to wear under any material, and durable.

I've got a few pieces of LD Comfort base layer, and none of them has left my closet shelf since I bought these Klim pants. To me they are superior in every way. This is blasphemy in the LDR community, but I call it like I see it.

You buy now.

Exactly what I was after, 3700 miles later
I bought these (2 pair) to use as a base and only layer under Firstgear TPG Escape Pants for a 9 day trip. Love them and wonder why it took so long to go this route. Fit was perfect for me: 37 waist 32 inseam. They kept me comfortable in 40-70 degree temps. No seams to irritate on 600+ miles days. The FG TPG pants are essentially over pants so they fit a bit too loose with Aggressors as the only under layer.

Nice base layer
Always a little cautious ordering big guy stuff. Sometimes the sizing is way off but not this time. Fits great and is reall comfortable.
I highly recommend these.

Nodak winters.
I live in Fargo so I use these all the time. I'm 6'6" and 245lb and the 2xl pants fit just right. I bought from zilla on sale so they were definitely a bargain.

Finally, high qualtiy underlayer clothing which fits.
I have been a long term Alpinestar buyer. However, none of their clothing fits anymore. All sizes run extremely small, and the quality is lacking. I bought the underlayer Alpinestar pants and shirt at the beginning of last season. I am 5'10" 187 lbs. I needed again to get a bigger size XXL... The pants don't stay up.

Just bought the Klim pants and shirt for a fraction of what I paid for Alpinestar gear. It fits. (medium) It is high quality, though I still need to wear in really hot weather as it does seem heavier weight. Still, highly recommended.

Would this be good for a hot track day under a suit?
Mihai V on Dec 7, 2016
BEST ANSWER: I would totally wear these under a leather suit for a track day, but most of my riding is offroad. Either way, great for hot weather under your riding gear --whether a leather race suit or enduro body armour protective suit. I've worn this in some very warm weather and it works very well.
Is this a 3 to 4 season baselayer?
Donavan A on Dec 2, 2016
BEST ANSWER: To me, it's mainly a fall/winter type base layer. Would be very hot in the summer. This under a pair of jeans and I am good on a 40 minute highway commute down to about 40F. I'm on a BMW GTL, so I have a fair amount of wind protection though. Hope that helps.
What is the material and percentages of each?
Michael B on Oct 2, 2016
BEST ANSWER: The pants are 83% polyester/17% spandex. The inside is a soft fleecy feeling layer and the outside has a smooth feel to it. I just returned from a 6,000 mile trip from Florida to Maine and into Canada and back. These were my favorite of all undergarments (under armor and other sports performance shorts) used during the trip they were good at moisture wicking and keeping you comfortable. I was very happy with them. David
