Nice, but not for Deep South Heat
After being impressed with the KLIM induction jacket and gloves, I was looking for a base layer option. I watched the video and did my research. It should have been a clue when I saw this was a 4 season shirt and was fleece lined. "cool in the summer and warm in the winter" should have been another. Also should have taken another look at sizing. Also you will notice that they say this is a base layer to be worn under a mid layer. That should also be a clue. I am big guy and I ordered the 3XL First thing be aware that this fits like a second skin. Very form fitting and snug. Its plenty long enough, but it does fit close to the body ( exactly how they say it will) I was inside in the nice AC when I tried it on and immediately noticed how warm I started getting. I thought now way in Billy Blue Blazes this is gonna keep me cool. I intended to use this under my mesh induction jacket.

Well I decided to take a chance because it appears very well made. It should be noted I ordered the aggressor briefs as well and wore them at a 95deg track day last weekend. Ill post that review as well. But I will say here, they worked much better than the shirt. Probably because they are not fleece lined.

So, it got up to 98deg today with a heat index of 110. After 200 miles I can basically say that they do in fact wick moister very well. I was dry close to my skin and the outer layer was damp. BUT, my under armor gear works much better. I never really over heated but was certainly not as comfortable as with under armor.

Since I have now worn and sweated in them I am sure they cant be returned, but not sure I would anyway.

I think these will be much better for fall, spring riding. They will probably work best under a Aerostich windblocker jersey or even a Gerbing jacket liner. So if you are large guy like me (6'4" 280lbs, with a 52 chest and 46 waist this will be pretty snug. Just bordering on being too restrictive. Certainly do not wash and dry it or would never fit again.

So with that said, do not buy this for your summer gear arsenal. Stick with lighter under armor.or Nike dry fit shirts and pants.

Couldn't ask for more !
2015 is my first year riding and I decided to go all out with KLIM Gear. I rode about 20 times and this undershirt has performed extremely well. Wicks away the moisture on those hot days and keeps in the warmth on those blustery April and November days... Well worth the investment... I look forward to trying v2.0 soon !!!

Just Do It!
I've known Klim for a while and had never thought for base layers - I've always done wool base and mid-layer for winter riding. I ordered the Aggressor Pants and Shirt during the Xmas sale and man, what a deal!

Let me tell you, riding this weekend in the 40s with rain one day and dry the next, I didn't even take this stuff off! I was so warm the second day I took off the wool sweater so it was just the Aggressor underneath Klim Badlands riding in high 40s and low 50s. Truly surprised at how well it kept me warm!

The fit - it's definitely on the snug side but that's how a base layer should be. I'm 5'11 205lbs with thick thighs and a bit more around the middle. I ordered a Large in both pants and shirt. Initially I thought the pants were too tight but once I pulled them into position, I realized these were perfect. Almost fitting like a compression suit. The fabric is very stretchy and gives in the right places. The shirt doesn't give as much (not like a cotton tee or anything) but once it's on, it's perfect. I even like how long it runs to cover by backside - no drafts here!

Overall, whether you're skiing, hiking, riding, or whatever, this is a great product and at the Xmas price, it's a no brainer.

Just do it!

Great base layer
I got these on sale. I'm 178cm tall 185lbs 41 inch chest 33 jean size and I got the medium both the shirt and pants. They fit snug like second skin like they should be. I have not tried them riding but I tried them on indoors and they felt good. Shirt can be a little thick in the summer I think. Overall I'm happy.

great product from Klim
As with all Klim products, these are great! I got the shirt and pants, and like all wicking layers, the fit must be tight to work. A large shirt and medium pants work well for me (5' 11" at 175#). I live in MI, so ride season is over, but quality and fit on this set is very good. I can tell that they will be great for early Spring rides (if I can wait out another long michigan winter)!

Good product
I bought the shirt in a large, but needed to return it for an extra large. Great customer service at Revzilla. The shirt seem to run a little small. I also bought the pants in a large and they fit perfectly. I'd suggest using the same size you get in Under Armor when buying this product, if you buy Under Armor. So far I have been very pleased with the fit and performance as advertised. A little pricey, but well worth the money.
