I absolutely love these bibs!! I have put many hours into these bibs mainly for snowboarding and backcountry touring with my snowboard. The side vents are really awesome when it gets hot, and they are really easy to zip up ad down when its below 0 and when you have your gloves on. The last pair I had the zippers were waterproof like these but sucked when it was near 0 and you were touring for the whole day. The front pocket is really nice for phones and small camera gear (gopro) to keep warm or out of the elements when you are taking a breather from crushing it. The bigger front pocket is also really nice for gloves and hats when you are hiking or skinning. The only draw back to these bibs are that they are cold, there is no insulation in these bibs so you better but one more layer on your bottoms then you are used too. Even though they are super waterproof thy are also really breathable, besides boot packing and skinning I have used them during long steep winter hikes and mountaineering trips.
Overall I would recommend these to anybody who wants to upgrade their pants situation.
