After my outstanding experience with the Stio Environ jacket (review here), I decided to give the Stio Environ pants and Environ bibs a try. For many years I have been a fan of another CO-based ski pant, but they were just a bit too baggy and I was having some waterproofing issues in the seat. There isn't much of anything I don't like about the Environ jacket, so I figured I would like the pants version. There are two versions of the Environ pant: one is designed more for inbounds, and the other is a mini-bib with features oriented toward touring. The differences between models aren't clear, so I purchased both versions via Stio's pro-program last season and got in about 40 days wearing both styles. The pants' MSRP is $389, and the bib lists for $449. I am 6 ft 168 lb with a 33-in. inseam and 32-in. waist, and I am testing a size medium.

The two versions share the same materials and high-quality construction, but there are some key differences that you should understand when deciding between modes. Let's start with what they share. All Environ products (pants and jackets) utilize Toray Dermizax three-layer waterproof/breathable material. Dermizax membrane is rated at 20,000mm waterproofness and 10,000 breathability. The material is a 150 denier with an 80/20 durable water repellent (DWR). The fabric is a very tightly woven, pliable material but its heavier weight feels substantial and burly. Both pants have generously sized Cordura kick patches. All seams are sealed, and Aquaguard zippers with silicone grips help ease of use with a glove. Both models feature articulated knees and internal pant gaiters. For my use in Colorado, this combination of abilities and features works very well. Build quality is right up there with any top-quality manufacturer.

The Environ pant is built for the resort environment. It has a few extras that we will explore and a design oriented more toward comfort and style. It weighs about 840 g. Its features differ from the bib in a few ways:
  • Fleece-lined front hand pockets that actually add a little insulation to your quads
  • Flap covers on the zipper on the hand, thigh, and rear pockets
  • Adjustable waist
  • Belt loops
  • Thigh vents running from butt to knee with a double-ended zipper

The Environ bibs are best described as a high-waisted pant with a higher back with suspenders. They are designed with the backcountry in mind, or maybe just for those who want a pant with a cleaner design and extra coverage. They weigh about 770 g. They differ from the pants as follows:
  • Ample-sized waist with room for layering and elastic back panel for comfort
  • Fixed, adjustable suspenders
  • Full-length zippers that can be partially opened for venting
  • Side zipper snap covers at the top and bottom
  • No rear pockets
  • No flaps on pockets
  • Hand pockets are not fleece-lined

Fit and Comfort

Both of these pants are what Stio calls its relaxed fit, but in reality, they are neither slim nor baggy -- just about right for most skiers. They have a slightly full leg that allows freedom of movement but doesn’t look baggy. Stio's sizing guide says the medium has a 31¼-in. inseam, but it is longer than that. I wear a 33-in. pant, and these fit fine. If you wear a 32, they will fit just fine, too. The waist is ample; even with base layers and my shirts tucked in, I still have to adjust the tabs on the pant and have plenty of room in the bib. They feel good when on; the fabric is pliable and doesn’t make the dreaded swoosh-swoosh noise. I really enjoy the higher-waisted bibs for comfort (I don't like belts on my pants) and extra protection on deep or uber-cold days. The suspenders work well; they were easy to adjust and stayed in place.

Performance

The Dermizax material really does its job. The 20K membrane is paired with an excellent DWR finish, and I never had water permeate the DWR or fabric. The 10K breathability is ample for most skiing. If I’m really working hard or if the temps get warm, there are times I notice a little bit of moisture, but not enough to worry about; in those cases, I just open the vents, anyway. This can be a good thing because I find fabrics that breathe at exceptionally high levels (Event, Neoshell) let too much warmth out on really cold days. The fabric is windproof and did a great job during some fierce storms. When skiing, the fit of the pants and fabric are very comfortable. The articulated knees work well as do the zippers.

Durability

After skiing trees and bumps (and just through general wear), both models have held up beautifully. Even aspens and evergreens have not scratched the material. Dirt and such has washed off easily (although I didn't test with chairlift grease). The kick pads have scuffs but no tears.

Summary

Both of the Environ pants are highly recommended and have become my favorites. I personally prefer the bibs, but either model is fantastic. They are great pants with just the right fit and features and are constructed meticulously. No, they are not the cheapest pants out there, but you can often find a 10-15% coupon on the site. That makes these an excellent value in my book. They are backed by a solid guarantee and outstanding customer service.

  • Who are they for? Any inbounds skier will appreciate the quality, fit, style, and comfort of the Environ. Inbound skiers and backcountry skiers who want a cleaner, pared-down pant or who appreciate a slightly higher cut front and rear will love the bibs! If you are a AT skier who is looking to shave weight with an even more breathable pant (or jacket), see Stio’s new Raymer line.
  • Who are they not for? I can't think of anyone.

Weight: 170 lb

Years skiing: 26

Days per year: 60 plus

Home mountains: Steamboat, Arapahoe Basin, Copper Mountain, Loveland

Preferred terrain: Bumps, trees, steeps, powder, perfect groomers

Skiing style: Technical

Preferred ski characteristics: A combination of fun and serious: I prefer more damp skis with a medium to medium plus flex but the far end of the tips/tails should have a bit more flex. They should be lively with good energy and have an excellent snow feel. For frontside skis, the tips should engage well but not be an "on/off" ski. I like to feel the entire length of the ski through the turn, tip to tail. It should hold a carved turn but be able to be skied into any turn shape without fighting. I am not a fan of rocker on frontside skis so I prefer as little as possible. For powder and off-piste skis, I prefer a lower splay with a longer run rocker profile, an even flex pattern with a medium plus stiffness. I like to be able to drift a ski in trees, bumps, and powder but also drive the tips in bumps and on steeps.

Boots: Atomic Ultra Hawx Pro

Skis: Blossom No 1 SL, 165; Augment 77 Ti Carbon, 175; Blossom AM85, 178 ; Salomon Stance 96, 182; Moment Wildcat 108, 184; Moment Wildcat (116), 184

About me: At 57 with more surgeries than you want to know about, I depend on skills and strive to ski efficiently. I prefer skis that reward good technique as it makes skiing easier and more fun. I love taking out my Blossom SL's on bluebird groomer days and live in the trees and bumps on a powder day with my Moment Wildcats.

I can wholeheartedly agree with these sentiments @Dwight

After bout fifteen days thus far this season I have really enjoyed them. I also prefer the fit, finish and waterproofing on these better than what my 150+ days on that baggier Colorado braded gear as well. Well done Stio, well done.

Glad you liked them as well. Thanks for sharing your experiences.
 
Ron,

Would you say if I wear a Large in the Environ pants, which I do, I would need a Large in the Environ bibs or do you think the bibs are roomier in the waist that I could get away with a Medium? 34" waist.
