I was really looking for bibs, but I realized that most of them have full size side zippers, except for a few ones (Oakley Sethmo, is one I can remember). For those that actually use full size side zippers bibs/pants are there any advantage/disadvantage compared to regular side zip vents? Looks like having the zippers going all the way down is not really an issue, but having them starting at the waist seems a little inconvenient because you have to deal with your jacket and backpack belt if you use one. I would prefer something starting ~6" down the waist level going all the way down.
Any thoughts on that?
The Arcteryx bibs have a full side zip that goes up to about mid hip and has zippers on the top and bottom. You can zip the top zip down for ventilation (it is below the waist belt of any pack) and also put the pants on with your boots on because of the long zip. It's totally the most well thought out system. I have the old pro shell ones ( Alpha or Beta or whatever) and they have lasted seven HARD seasons. Just ordered the new Theta SV's that look similar . They are much better than pants - you never ever ever get snow up your back.
