Our Verdict

The Outdoor Research Hemispheres Bib - Women's is a versatile and weatherproof bib that has all of the features one could want for backcountry travel while remaining comfortable and effective. The 3-way stretch Gore-Tex means that they move with you in all the right places, becoming more of an extension of oneself than something to be fussed with on the skin track or during transitions. To top it off, they come equipped with ample pocket space—including an avalanche beacon pocket—plenty of venting, and top of the line waterproofing to be ready for any adventure. If the price isn't a limiting factor, treat yourself to the Tesla of backcountry ski bibs. For ski touring applications, we can't recommend another pair of bibs more highly. Note that these pants are unnecessarily technical for most middle-of-winter resort skiing unless you frequently hike inbounds to your favorite spot.

Our Analysis and Test Results

The Hemispheres Bib was a standout during our testing process. Surprisingly lightweight for a pair of bibs, it's a three-layer Gore-Tex shell with no insulation. The 70-denier nylon external material is well constructed and should be durable enough for multiple seasons of use. The drop-seat feature, which we wish all ski bibs would include, makes using the restroom possible without removing your jacket — a huge benefit. There is a pocket with a clip for storing an avalanche beacon, too. These are pricey, but you won't find many better backcountry-focused bibs.

Weather Resistance


These bibs exceeded our expectations during their weather resistance test. The Hemispheres are made with a combination of 3-layer Gore-Tex and a stretchier 2-layer Gore-Tex in key areas where stretch is beneficial. We can't lie; we were skeptical of how the 2-layer spots would hold up. The material is ridiculously stretchy, and it seems like wind and water would go right through.

That wasn't the case. We never noticed wind coming through the stretch material or the 3-layer Gore-Tex, and these pants completely withstood our 2-minute shower test. We focused the water on all parts of the pant, especially the zippers, vents, and different materials, and no water got through.

Fit and Comfort


One of the standout features of the Hemispheres is its comfort, as Outdoor Research thoughtfully designed the bib with movement and stretch in mind. First off, it features articulated knees, which allow for uninhibited movement, especially when going uphill, as this gives extra room in high mobility zones. Second, they outfitted the bib with a stretchy Gore-Tex material in key tension zones, such as the crotch, sides, and lower back, allowing for uninhibited movement where you need it. This material is instantly notable for its stretch and comes in handy, especially in the backcountry, where stretch and space are key to crushing it both up and downhill. The fit is also forgiving if you need to layer up underneath.

Finally, the comfort of this bib is notable, with highly adjustable straps allowing a wide range of fits and heights to wear the bibs comfortably. They are baggier in the chest, which allows for a larger range of body types to wear the bibs without difficulty while still providing coverage and protection. While this baggier chest fit may not be for everyone, it certainly allows for versatility in the wearer and requires a less specific fit than a typical pant, which measures at the waist. The slightly relaxed fit works well for this product's intended use - enough fabric to allow movement without having too much material that would impede movement.

Ventilation


Two zippers, outside each leg and abdomen, help cool you fast and give you many options for where and how much air to let in. The two-layer stretch Gore-Tex is also incredibly breathable, with strategically placed stretch panels in areas such as the inner thighs and lower back, where heat may build up.

The Hemispheres Bibs take ventilation seriously with massive, mesh-free vents that span from the top of the bib down to the top of the knee.

Warmth


These bibs score low for warmth, as can be expected for any shell product. They simply aren't designed for that but rather to keep the elements out and add protection. That being said, they have ample room for layering underneath, allowing wearers to customize their level of warmth depending on what their day on the slopes calls for.

If you are someone who doesn't feel like they need added insulation in their pant and prefers a shell option, these pants will meet your expectations. If you prefer the added warmth to be built into your pants, these are probably not for you.

Features


The Hemispheres Bib is fully loaded with thoughtful features to make your next backcountry adventure a success. First off, it has four pockets that are spacious and well placed. The two thigh pockets are roomy, and the right pocket comes specifically with space to fit an avalanche beacon. The kangaroo chest pocket is the largest we tested, making it easy to warm up hands, keep a phone, stuff your gloves if things warm up, or more. Finally, the horizontal chest zipper pocket is an easy space to put keys, lip balm, a lift ticket should you be inbounds, or other small items that you want to keep at hand.

Another feature to note on this bib is the easy to use drop seat for when nature calls in the backcountry, making it easy to go without having to remove your jacket or other top layers. It has a ski boot power strap cutout in the boot gaiter to allow for easy integration.

Style


The OR Hemispheres Bib doesn't really turn heads with its style. It comes in only two color options, making it pretty limited if you dislike either color. That being said, both are pleasing and muted.

The overall bib aesthetic is just alright for these, and the fit of the legs is flattering for most body types. One thing we did notice is that the chest of the bib is baggier. If you prefer a style that is more form-fitting, these may not be for you. The overall style and look of the bib is one of technical performance and may appeal to those looking for utility over a pant that stands out from the crowd.

Value


The Hemispheres Bib is pricey, without a doubt. If you can afford the splurge, these pants are sure to deliver. If you plan on spending a lot of time out in the backcountry, you want a pant that can keep up with you and deliver. These bibs are that. We would recommend these for an avid backcountry skier or splitboarder who expects a lot out of their gear. If that is you, then these pants are certainly worth the cost, especially after multiple seasons of use.

You can tell through its thoughtful design that these bibs are made to thrive in all conditions while keeping the gear you need for success close at hand. Backcountry skiers, these bibs are for you.
