The Icebreaker Leggings with Fly provide convenience, performance and comfort. What more do you need?

The Icebreakers Men's BodyFit200 Skin Leggings with Fly give you the warmth and technical properties of the best base layer around, with the convenience of a fly. Never fear, flat seam stitching means the fly won't add a ton of bulk and won't chafe you silly on uphills. Made from merino wool, the lightweight Skin Leggings give you the best breathability and moisture wicking you can get, bar none. Merino wool isn't itchy or prickly on your skin like the more common lowland wools, and naturally resists odor so you don't offend your friends on the ride home.

Too Delicate

Tried it, but it was too delicate. I returned it for the patagonia version. Best decision I made.

Just got a pair, but I have a question...Are you supposed to wear underwear with these?

Excellent skivvies.

I have had a pair of these for just about a year, and they work great. They work well for skiing, tucking nicely into my icebreaker ski socks that I also enjoy. Also I use them on my cold day bike commutes under my soft shell knickers. A bit on the pricey side, but they look like they will last for several more years, a good investment indeed.

Comfortable, snug fit

I just received these in the mail, top and bottom, and wanted to try them on and give a review.

I am about 6' or 182cm and 170lbs or 77kgs. I have a 33 inch waist, 41 inch chest, athletic build.

The fabric and seam quality look and feel great. It looks like it should hold up for a while and not break down so easily.

The fit is "FITTED" This thing is snug! I ordered LARGE and wear a medium in every other base layer. It would be wise to order one size up than what you usually wear or I imagine it would be very tight and probably unwearable.

For the bottoms, with the crotch seams seated up in my crotch as comfortable normal wear with the waist band sits above my hips in my waist, where it should, and the ankle seams comfortably reach down to the bottom of my ankles with no bunching. The waist band is not overtight and rides comfortably where it should. The only negative is the fabric feels a bit tight around my upper calves. It is a snug fit with no looseness anywhere. So overall, it wears like it's designed. I have yet tested it in the weather so can't attest to it's warmth.

ORDER ONE SIZE UP than what you usually wear.
Buy an insulation layer to wear over this garment.

I also reviewed the top so check it out. Have fun.

How does the sizing on these compare to the 260 BodyFit Leggings?

I'm 6'2", 185lbs, 35 waist and about a 33 inseam and M in them is an almost perfect form fit when I put them on, just bordering on being too loose by the end of the day. Same deal w/ the 200 weight or do I need a L to not feel constricted/compression?

The BF200 leggings will fit a little tighter because the fabric is thinner so I would say go with the same size. You can also check out the GTBaselayer bottoms- they have a touch of lycra for a little more stretch.

BEST, hands down!

Buy these and stop whining!
You will not find a better pair of legging pants on the market. I wear these under pants. Under shorts with smartwool knee high socks to run in. And even wear these to bed when camping. They always stay dry. Never smell. And feel great against the skin. Keep you super warm and toasty when needed. I say buy these and wear them for three days. If you don't agree that they are the best in the biz, then move to Russia and wear their crap!

Icebreaker Bodyfit200 long underwear bottoms

Icebreaker is the bomb. These leggings are sooooo comfortable and keep me warm. They feel so thin. I live in Aspen and wear my body fit 200 under my clothes all winter.

My go to long johns

I've retired all my traditional running tights for the IceBreaker Leggings and they are great! Never going back to synthetic tights again.

Magic Pants

These are amazing. No smell, kept me warm in about 20deg, kept me cool in about 80deg. Very well made, and versatile. Soft, still not as soft as cotton or silk, but still very soft. I love these pants.

If you do anything outdoors in temps around 15-70deg, these are for you.

These keep me warm in the coldest of temps. Very high quality.

Excellent Value

I’ve used many thermal layers in my lifetime and this particular product ranks near or at the top.Very easy to wear with a good stretch and excellent warmth considering the weight. The product wore well under an outer shell and at other times with jeans.

This product was used in temperatures of -36° F without issue and even at +32° F it was providing me adequate garment breathing and no over-warming occurred.

For use as experienced with temperatures between -36° F and + 32° F I rate this product 10 of 10

For use in conditions above +33° F the product may too warm.

nothing beats icebreaker

I've tried SmartWool but it just doesn't last.
Icebreaker on the other hand is awesome: warm, durable, comfortable.

I'm trying to decide between these and the patagonia capilene 2 bottoms...

I'd wear them under jeans to keep me warm on my way to work (5 mile bike ride)
and on weekends to go rock climbing.

The temperature ranges during the day from 35 to 60

Responded on

I'd for the icebreaker and the wool. Its better over a greater range of temperatures, does better with moisture management for the most part and will not start to stink after a few rides.

Responded on

I totally agree w/knanier above. I was a user of Patagonia's capilene base layers before I switched to wool a couple years ago and am never going back. I love these leggings and can't imagine going back to the synthetics again.

This Icebreaker layer has worked very well for me.When used under any windstopping material,I have been more than comfortable even during hard physical labor.

I'm looking for some lightweight long johns...

I'm looking for some lightweight long johns for hiking and biking around Iceland in november - my research indicates that either the Icebreaker BodyFit 200's or the SmartWool Lightweight Bottoms are the way to go. Can someone who has tried both chime in with their opinion on which is better?

Question number two I unfortunately have to wear a light knee brace while exercising - would it be a problem wearing that over a pair of light long johns?

Responded on

The quality of Icebreaker is as good as it gets. I have used both and prefer Icebreaker to SW.

Regarding your knee brace wearing with wool long underwear...just be careful because they do tend to snag.

May you be healthy.

Responded on

I have both the Icebreaker and SmartWool long bottoms and think they are both high quality items in both fabric and construction and could recommend either of them. I do however prefer my Icebreakers because I like their fit better. They're a more 'athletic' fit and as such they fit well under all of my clothes plus I can wear them alone to run in instead of traditional running tights.

Solid baselayer

I've been using these for two years now, for both skiing and for some cold weather backpacking. These are a very comfortable baselayer that has a good fit and the fly is a definite plus for me. The pants appear to be well made, and they wash well in a washing machine. I have two complaints - the first is that they appear to be stretching in the second year of use. Not to the point that they aren't usable - they still have a snug fit - but it is obvious that they are no longer returning to their original shape. Second - I have a pair of REI MTS merino wool pants that I got for a fraction of these that are every bit as soft, comfortable and good-fitting, and the REI leggings haven't stretched. REI doesn't appear to be making these any longer (very disappointing - they were a great deal), but this is one of the rare cases where I found Icebreaker to be second place to another brand.

Favorite baselayer part two

I loved the 200 tops, so I got these and ditched all my other bottom baselayers. I'm 5'8, 150 and the mediums fit perfectly.
