    Full weather protection for pleasant ski trips.

    Whether you ski or snowboard over backcountry or corduroy, the Arc'teryx Women's Theta SV Bib has the full weather protection you crave. Its nylon face has an X Gore-Tex pro membrane that's waterproof and windproof so you stay cozy no matter what blizzardy weather you're facing and that's breathable so your legs won't get sweaty. Plus, Arc'teryx added X Gore-Tex reinforcements at the knees, seat, and lower legs so you're doubly protected in critical areas. The Theta SV has an athletic fit and e3D patterning that follows the contours of your body, lets you move comfortably, and lets you layer easily underneath the bib.

    Two full-length side zips run down the Theta to help you put your boots on and to provide venting options. The side zips and snaps up top also provide a drop-seat option so bathroom breaks are faster than ever.  Also keeping snow out are the comfy Cordura powder cuffs that have boot clips for your convenience. And a Keprotec patch covers your instep to protect the bib from boots and other abrasive features so you'll have the Theta SV for multiple seasons.

    Awesome pants and good fit!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: S

    I wore these for the first time on an April weekend at Snowbird after a few inches of powder. It wasn't particularly warm out (high 30s), but the pants kept me very warm and dry. I like a less tight fit, so I am a fan of the room you get in these (but I get why some reviews have said that the pants run large). The pockets are certainly not large, but I wouldn't want large pockets there, they fit chapstick and an ID and credit card (which is useful). The material is really great though, light but breathable, I'm excited to use this bib more.

    Great fit and quality

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

    I've used these pants for resort and backcountry riding and they have performed well in both conditions. The fit is trim, allows me to wear a base layer but not overly baggy. After years in a non-bib pant, I'm disappointed I didn't invest in these sooner as I no longer have to worry about getting snow down my back with these bibs. The only down side is the same comment the other reviewer mentioned: the small pockets. They are only good for a chapstick but then they are high enough where it's difficult to unzip the pocket with a layer on. I would expect backcountry ski pants to have at least one pocket big enough for a beacon.

    Amazing bibs

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

    I've worn these bibs for 3 seasons of winter touring (splitboarding), and they have performed extremely well. I've worn them at the resort, too, and they have proven to be durable and comfortable. My only gripe is that they don't have thigh pockets - the only two pockets on the bib are inconvenient to access as they get buried under mid and outer layers. I found the fit to be trim (rather than roomy), but not tight.

    great fabric,but runs on the bigger sid

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

    I am an XS, 5'7, 105. these bibs ran on a larger XS. I was a little disappointed on the fit. from thew photo it looking like it has more of a womanly fit. GOR-TEX is a great water proof fabric, unfortunately the fit did not work out

    I am looking for a trim fit ski pant in...

    I am looking for a trim fit ski pant in black or navy. I am petite, 5"4" and 105#. I have yet to find a ski pant that feels and looks good on me :(. (I am 54, and looking for something not baggy). Will this model in XS work for me?

    The Theta Sv Bib is part of Arc'Teryx's athletic fit line and is a good slim option for most. Other athletic fit options to consider are the Arc'Teryx Stingray and Morra pants. The Gamma AR pant is a trim fit (slimmer even than the athletic fit) and could be another option for you, but as a climbing inspired softshell it wouldn't be an ideal choice for all skiing conditions.

    Hello, I'm somewhere between s and m, waist...

    Hello, I'm somewhere between s and m, waist one cm smaller than s, hips one cm bigger than s. Shall I order s or m? Some users giving their commets have mentioned a bit too much space. Could you help please? Thanks Kate

    Hi there, I just came back from the arcteryx store here in vancouver, bc where I was trying on the theta bib and tough luck on the sizing. With arcteryx products, small always fits perfectly but with these pants I found S to be a but too baggy around my waist and bum. I tried on an XS and while waist was a nice flattering fit the hips were too tight in XS. It also depends what you typically wear under your ski pants. If a pair of light-medium weight long johns then I'd say a Small will be all right.
