    Bibs for supreme protection as you float through waist-deep snow or run laps in the park.

    Bibs are the ultimate commitment to winter—they're a serious tool for shredding the deepest powder in the worst weather. Marmot designed its Men's Rosco Bib Pant with waterproof breathable fabric, a loose cut for layering and style, vents to control temperature, and enough pockets to store all the gear an army could carry. Rock this pant on the tram, when you duck the ropes into the backcountry, or when you're running laps in the park.

    • Precip technology uses a waterproof breathable membrane in order to keep you dry in wet weather
    • Fully taped seams mean water won't seep in through the seams
    • Loose cut provides a comfortable fit and leaves room underneath for layering
    • Articulated knees ensure that you have full range of motion right where you need it most
    • Inseam vents allow you to cool down quickly after a hot hike
    • Stretch softshell in the bib panel adds comfortable flexibility
    • Waist tabs help you dial in the fit while a zip fly makes it easy to do your business without fully pulling off your bibs
    • Cordura scuff guards protect the pant legs openings from wear and tear
    • An array of pocket options gives you plenty of storage for spare goggle lenses and snack bars
    • Item #MAR2569

    Warm and Dry

    • Familiarity: I've put it through the wringer
    • Fit: Runs large
    • Size Bought: medium

    Baggy loose fit. Might run a little big.
    Keeps me warmer than other similar pants.
    Pretty tough material. I have beat the hell out of them and they still look great with no holes.

    The suspender fit adjusters don't really stay put. I usually have to readjust them each time.

    Super Warm!

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    I bought this as a gift for my buddy after seeing his old worn down ski pants that he'd been using for years. He's 6'2", 210lbs and the Large fits him perfectly. He used them for an entire day of snowmobiling in 5 degree weather and all he had on was a light weight baselayer and he said that these pants keep him extremely warm and dry the whole time. He highly recommends them.

    Great style and design but a major flaw

    • Familiarity: I returned this product before using it
    • Fit: True to size
    • Size Bought: Medium

    the snow cuff on this pant is the cheap elastic style, however not only is it not adjustable for tightening around the boot, but it is so loose that it just hangs loose over the top of a alpine boot, say nothing of an AT boot. Other than that the design and comfort of this bib is great.

    Great purchase

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: medium

    Wonderful pants and a solid value. They run true to size. i bought Medium and they are a tad long for my short leags (30 inseam). The suspenders do get twisted a little but love the snow protection that comes with that slight annoyance.

    Fantastic Bib Pant

    • Familiarity: I've used it once or twice and have initial impressions
    • Size Bought: Large

    I got this Bib Pant and it is a great ski pant, I originally ordered the medium size based on reading some reviews, and the leg length was just right. When I zipped all the way up however, it was a bit tight while wearing one thermal and one flannel shirt. I am just over 5'10" and weigh 180 lb. I knew if I were to wear a sweater or another thermal and a sweater that it would bee too uncomfortably tight. So, I exchanged for the size large and the legs are a little long, but this is a better fit on the upper body and I don't think there is too much extra on the length. I was skiing in 7 degree weather with two thermal pants on under the Roscos, and felt no wind penetration and was really comfortably warm and dry. For the price, I believe they can't be beat. Awesome pants. Tight at the upper torso, also one of the plastic clips that attaches the suspender to the bib kept twisting to the vertical position, it does seem a minor issue all the same, but the issues together lose a star in my view, but I would buy again because of the price.

    Regarding size:

      I'm 6'3'', 210.

      After looking at the reviews, I was split between a Medium and Large. Went with the large because nothing Medium has fit after the last 20 pounds. Happily, the Large fits perfectly. Length and waist are spot on. Definitely wouldn't need a XL.

      Bibs Are Sick

      • Familiarity: I've used it several times

      Ok, so, if you don't have bibs, you must like snow down your pants!

      On to these particular bibs. They are solid, no bells and whistles, but a really great bib. I have a few mild qualms with it. The sizing is a little weird, the torso is a little tight for the sizing of the legs, but is fine as long as you aren't short and round. I do wish they had put a 2 way zipper in at the fly and the vents could be bigger. Also, where the suspender attaches, as another reviewer noted, can turn sideways and loosen your suspenders. I solved this problem with a few zip ties.

      All mild annoyances, but they don't detract from these bibs. Still a great product and they will be plenty durable. I will be wearing them every day out on the snow from here on out.

      Solid Bibs, Good Value

      • Familiarity: I've used it several times
      • Fit: Runs large

      I've had these out in deep back-country snow a few times now. First, a couple of very minor negatives. They run a little long, and are much looser around the feet than I would expect for a technical bib. I like my gear to have an athletic fit so that it never gets in the way of my motion. Up top, the fit is athletic without being tight.

      That aside, these are awesome bibs! Mine are in yellow ("mustard"), and they look sharp. They are very waterproof—I have observed water droplets beading up and running off, and nothing soaks in. Granted, mine are still almost brand new, but they seem like they will hold up well. The reinforced Cordura near the feet seems bomb-proof. No ski-edge slashes there!

      Finally, the suspenders are wide enough to be comfortable all day, and the front zipper, though a little short, goes down plenty far for bathroom breaks.

      Though not quite perfect, these are true back-country bibs, and you'd be hard pressed to find a better value.

      Great for the $

      • Familiarity: I've put it through the wringer
      • Fit: Runs large
      • Size Bought: small

      If you want to spend $500+ on a bib go for it! For those of us on a budget these are hard to beat. I like the blue color, but sizing was a bit funky for sure. They fit loose and are big around boots at the bottom. I'm 5'9 150 and ordered the mediums initially believing I knew better than the other reviewers here. WRONG. The smalls fit me much better. My roomate (also a BC employee) usually wears a large and ended up taking my mediums. So they run a little long, but they are a little tight in the chest area. If you have a belly or are barrel chested you might look elsewhere. A few other comments: Cons first. The vents could be larger and need mesh to keep the snow out. The shoulder straps wear my nipples raw. I advise wearing two shirts (the struggle is real!). front zipper should have a bottom zipper also so you don't have to go under your jackets to unzip. This being said these are minor concerns that should not dissuade you from buying these. The gortex is thick and waterproof and the construction seems excellent. I am comfortable in them and love them for the price.

      Great for the $

      BOMB proof

      • Familiarity: I gave it as a gift but have feedback to share

      These bibgs are a loose fit, wicks moisture away quickly, and is everything you'd want in a bib. The only complaint the recipient had was, bathroom stops are more work than other bibs.

      They got the color right

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I love bibs in general because they offer unparalleled weather protection. Here are the reasons I don't love these bibs:

      1. The zipper goes from top of the bibs down to the crotch, this means that to pee in the woods, you have to open the jacket and unzip. This could easily be solved by having a double zipper working from both ends...

      2. The straps allow for the plastic rectangle that hold them in place to rotate. This means that when you set your straps length, at some point during the day they will become longer bu about an inch. It looks crappy and it changes your settings.

      3. The straps don't stay in place. Only if I wear a backpack, can I ensure that the straps don't slide off my shoulders. My other brand solved this by putting a non-sliding material on the inside of the straps which works great!

      4. The vents are tiny. I ride in Colorado and the mornings can be very cold, and by the afternoon it can be downright hot. The tiny vents barely make a difference.

      The bibs are durable, I have tested that. They are colorful and fun, but they don't live up to the asking price. I will be avoiding this brand in the future.

      Sizing and Fit

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: Runs large

      Just picked these up as my 20 year old snow pants bit the dust. 6'2" 180lbs and was very nervous to order the medium but glad I did. They fit great. Length is perfect, but I can see if I was in the 5'10 range they may be too long. If you are skinny sub 180 there are velcro adjustments on the waist. For some reason I really like the front zipper pockets. . . .maybe because my old ones didn't have. Remember these have no insulation just proofed outer shell and thin synthetic lining. For kicks we had some sub zero weather . . . negative 30 so I took them out. Well, I'm not going to lie they were cold but blocked the wind very well, I only need them for 10-15-20 degrees anyway. I think they are going to work great when I layer with they stoic wool long underwear I just picked up. I like the bib aspect too as Im wrestling around in the snow with my kids will keep dry!!!


      These Run Large!! but are Awesome!!!

      • Familiarity: I returned this product before using it
      • Fit: Runs large

      So sad to return these as the color and size I had planned on exchanging are now sold out I will now have to go with the mediums and pay more from the Marmot official site as they are almost sold out of everything on Backcountry unfortunately. That being said I love these pants they are quality made and are a great style, thats why I am willing to pay more for them but they run large!!!! I am 5'10" and 165lbs with a waist of 33" and the large are way too big you will need to buy a size down unless you like them really baggy. Once I receive the mediums I will be able to comment about how they perform which I am very much looking forward to.

      Great Pant on Sale!

      • Fit: Runs large

      Can't beat the quality of this bib for the money. Found these while Backcountry had them on sale and I couldn't be any happier. I am 6'1 / 175lbs. and the medium fits perfect. The lenght is right on the mark while standing in socks.(I don't like any extra lenght dragging on the floor so I went with the medium even though I typically wear a 33/34 waist) and the "loose fit" is comfortable but not at all baggy. Waist and bib fits perfect over a couple thin base layers. If your size is on the edge I would defintitely size down. Great details and construction. Way to go Marmot, I will probably pick up another pair.

      135 5'11 Small or Medium?

      Hey Guys,

      I'm 6'5 200lb would the Large fit me? I'm really just worried about the length,


      I am 6'0 and 175 lbs and got it in size Medium and it fit perfectly. I think L might be a bit too short, DOn't think going 1 size up will add 5 inches in length. It's also pretty snug around the waist. So I'd get XL.

      Fantastic pants, you'll love them. Very water proof and very functional with lots of pockets

      5'11" 195-200 lbs. 34-36 waist, 32 inseam. Medium or large? Danka!


      Alright try this one on for size. 6'3" 230lbs, typically a 36in waist.
      Would I fit the Large or X-Large?

      John W.

      I think that the XL would work for you, and with these being a bib you shouldn't have to worry about the waist size to much.

      You could also order both and keep the tags on them and decide which one would work best and return the other for a refund.

      If you called into 1-800-409-4502 or chatted in with a gear head online and they can get you squared away.

      6'1 200lbs, typically wear 33-34 waist and 32 inseam. What size should I get in these bibs?

      What's the k? Are they warm

      I am 5' 11" 170. Should I get the medium or the small? I wear 31 waist 32 inseam jeans.

      Do the gaiters have hooks for boots?

      Do the gaiters have hooks for boots?

      Hey Fung0_o,

      Thanks for your question.

      I took a look at the Marmot Rosco Bib Pants that we have on hand and inspected the gaiters. They do not have hooks for boots. They just have velcro and a snap with elastic and rubber to secure onto your boot.

      I hope this helps

      Can I get these with the short inseam? in...

      Can I get these with the short inseam? in Large

      I am sorry, but not only do we not have these in a short inseam, but we don't appear to have any short inseams available right now in any brand. The TNF Freedom pant is often available in variable lengths as are bibs from Arcteryx. Though at the moment we have only regular and tall. Sorry we couldn't be more help there.

      Size I like the look of the Rosco Bib ski...


      I like the look of the Rosco Bib ski pants BUT I have just tried a pair locally and found the waist only just OK and the leg length far too long so.... I am 5ft 10ins tall with (sadly) a 38in waist and a 44in chest. What size should I buy?

      Please reply to

      In my opinion you may be limited to an XL just because of your waist and chest but the only downfall is the legs may be just a little long I am also 5' 10" and I had previously tried on the L and the length was great I am just too skinny to fill them out any
