The Arc’teryx Men’s Theta SV Bib is a waterproof bib for all-round mountain activities in the harshest of weather. SV Stands for severe weather, and the N80p-X Gore-Tex is ready to keep you dry in Mother Nature’s worst. High wear areas (knees, lower leg, and the butt) are provided with reinforcement fabric for the long haul. The full length side zippers are coated to keep water out and make it super easy to get them on and off, without removing your boots. This waterproof shell has an expedition fit, providing plenty of room for layering on the cold days. Down at the bottom of the legs you’ll find powder cuffs with elastic and a lace hook to keep out the snow as well as Keprotec instep patches, which protect from hard plastic boot scrapings and ski edges. The Theta SV has a low cut bib, so you’re protected from rain and snow down your back, but features a front fly, for emergencies.

Products on Sale are Discontinued Styles or Colors.

Rated 5 out of 5 by from Ultimate Protection for Legs I bought the Theta SV's to go with my Sidewinder SV jacket. Both items are listed as "our most durable item", a claim that has so far proved to be true. I have had these for 3 years, and the wear and tear of months of skiing have so far failed to make an impact on them. They look as good as they did on the first day. The high waist and back keep out cold and snow, and the thigh zips prevent over heating on long skinning sessions. I particularly like the full length zips, which have disappeared from most other pants.

Rated 2 out of 5 by from chafing wedgie. I agree with the details and workmanship of the previous reviewers. These are well made, articulated and the fabric breathes, repels etc.... I have wanted these for over ten years. I just returned from a hut trip trip, with a lot of backcountry touring, to find that these bibs like to ride up. Initially, I thought I just needed to adjust the suspenders; Arc'teryx provides ample adjustments, no luck. I extended the suspenders all the way out and still they ride up. Eventually I just undid the suspenders and folded the bib section down to my waist. I tied the suspenders around my waist so they weren't dragging on the ground. They still rode up. My day of skinning was constantly disrupted by having to undo the waist harness of my pack, pull my pants back down, re-clip my waist harness and let the pants slowly ride up again. I am 6'0 185# and I purchased the large bibs. A simple web search will provide other experiences similar to mine. As much as I have coveted these pants for 10 years, I cannot recommend them with this known issue. Hopefully it has been/will be addressed in future models.

Rated 5 out of 5 by from The only Short Large Technical Shell Bib on the market I have been looking for the tech shell bib for my husband for more than a year now. "Theta SV Bib" is the only one I found for a short stocky man. I myself own the women's version of it and I love the dropping back panel, the reinforced sit, knees and bottoms. I skied in it last season and it kept me dry trough 4 hours of unrelenting rain. The fit is true to the chart. The only thing I regret is that I could not buy them in XL with inseam 29 inches: in cold weather we normally wear thick fleece underneath the shell and that makes size L tight. Unfortunately the XL is 2 or 3 inches longer, which makes it unusable unless you have ski boots on a all times - I hate it when the pants are dragging behind you in the salty puddles. All the retailers are permanently out of stock with Short Large size, and the size we actually need is for some reason completely unavailable. Why?

Rated 5 out of 5 by from Top Quality Bib Just received my Theta SVs. Here are some important things to note: Regarding the fit, I'm finding that the leg length is more than generous while the waist is snug. I'm 5'11", 165 lbs and wearing a size Medium. As a very slender guy, I'm surprised by the fit. As of this review many special sizes are unavailable, and it's not a surprise that this includes the Large Short. Thankfully, the Medium is going to work well for me so long as I keep a trim waistline. Please keep this in mind if you tend to carry some weight in the middle. The overall shape of the pant is great. It has a fairly trim look, with enough space for layering but without the bulk. The cut is a slightly crouched shape, with a bend in the knees instead of straight legged. There is a full length zip down both legs, which can come in handy for adding or removing the pant as conditions change. Suspenders are very comfortable. As other reviewers have noted: The only two pockets, located at the top front of the bib, are certainly small. Perfect for lift cards or a compact camera, you'd be hard pressed to fit a full size smart phone in one of them. Personally, I like them and will stick to putting most items in my jacket pockets. I purchased these Theta SVs in Chipotle color and I'm happy with my choice.

Rated 5 out of 5 by from Great multi use potential Great product, I used th on a two day winter walking trip in Scotland and I was very impressed with their breath ability. I have also used them dry tooling on a very wet day in dunkeld. Great fit and hard wearing. Well designed built in gaiter. You don't need to be a ice climbing hero to get a lot out of these trousers. Worth every penny.

Rated 5 out of 5 by from Wicked rippah!! Wicked rippah bibs, guy. Easy to move with full range of motion but no excess of fabric. I have yet to use the drop seat functionality but I hear that it's a unique opportunity in the cold. If you're willing to pony up and pay the price I would absolutely recommend these bibs. Fantastic fabric and build quality/design. The only down side is they don't come much higher than the waist in the back. If you fall in powder while skiing, there is a possibility snow could travel up your coat and then down into the bibs. Other than that these are fantastic.

Inseam / Pant Length - From a standing position, measure from your crotch to your ankle.

• Please note that all the info provided above refers to body measurements, and NOT the dimensions of the garment.


Next to Skin Fit - These snugly-fitting garments are made with stretch fabrics to fit next to the skin to enhance moisture management and thermal efficiency. Garments in this fit category when constructed using Arc'teryx's heavier-weight AR and SV fabrics also perform very well as mid layer pieces, and users should consider selecting a larger size to accommodate a base layer underneath if the intention is to use this layering system as a mid layer option.

Trim Fit - Trim-fitted garments share the motion-friendly traits with Arc'teryx "Athletic" fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments.

Athletic Fit - This is the "Arc'teryx Standard" fit. These complete patterns utilize anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.

Relaxed Fit - Relaxed fit garments rely on higher volume patterns and a reduced amount of articulation to offer roomy mobility.

Expedition Fit - Cut roomier than the Arc'teryx Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.

• You can find the fit type and additional fit info for Arc'teryx styles in the product description FEATURES and SPECIFICATIONS.
