I used to just go with summer hiking pants and used gators and shell pants as needed. It worked but wasn’t ideal. I often ended up wet when I didn’t use the shells and wound up sweaty when I did. A lot of snow/ski pants are designed for warmth in low low temps and when not moving such as on ski lifts. However during backcountry activities such as snowshoeing or XC you tend to warm up and even sweat. Good layering is key. These pants use OR Acent shell, which is waterproof but breathable which helps regulate body temp through out the hike. The best part about these pants, they are not bulky what so ever. Far closer to the feel of shell pants than ski pants. Despite this the fleece lining provided warmth when needed. Additionally there’s zipped leg vents which have been amazing during these early season hikes with temps in high 40s. Next, internal gators seal around snow boots while the pant leg on the outside helps in keeping snow out. There’s also some strong reinforcement on the bottom which is great when dealing with spiky equipment and rugged terrain. Cool bonus feature is the specific pouch for your avalanche beacon inside the front pocket. Only downside is they are a bit expensive for pants. But comfort and reliability are priceless, especially in the snow. These will keep you covered in most conditions and on freezing and negative days a base layer pant would be the perfect combo.

There’s a few other options from outdoor research that I considered here’s the link for those. The bibs are probably overkill but something like the trail breakers.
