I just bought a Gerbing EX Jacket, Gloves and Pants. The Jacket was a 3X and fit well, The Gloves were a large and fit well. Both of them work great. I feel I will be able to ride at 0 degrees ambient comfortably as long as there is no ice on the roads.
The pants however were a different story. I actually wear a size 44 Levis on the weekend but during the week I wear a size 48 and suspenders so they won't literally fall off as I am standing there. This is for concealed carry at work.
So I ordered a pair of 3X pants feeling that they should fit relatively well or a bit tightly but usable.
I bought them at Revzilla and when I called for an RMA I did not even get the chance to tell the guy anything other than "Hi, I bought a Gerbing EX Jacket, Gloves, and Pants.....
You can stop right there...you want to return the pants because they are way too small, right?
Uh...Yea.
What size did you order?
3x.
And what size do you wear?
44 privately and 48 at work with suspenders.
Yea...I was the first to try on the 3X Gerbing EX pants. I have a size 44 waist and there was no way I could even get them up to my waist. Our policy on these is to pay for return shipping...Right now I'm gonna email you an RMA number and a shipping label so you can just drop it at any UPS store and walk out. We've had some long discussions with Gerbing and they are going to fix this but not soon." So I sent them back...Be Warned.
So I bought a pair of Joe Rocket Ballistic 7 pants in 5X because so many pants do not offer larger sized unless you are talking about custom leather pants which would be useless in the winter without a very nice lining.
These pants are great. They have zippers in the sides but I don't need them. They have a really solid, thick waterproof lining that zips out if you need it to. Some of the Revzilla reviews say that the owners can ride down into the high 20's without the lining and that the pants would be useless in the summer due to a lack of ventilation. I think that's right but that works in my situation.
If you are using a heated jacket or jacket liner and heated gloves, I think these pants with the liners in them will not let you down even if you are in the single digit ambient temps with an 80 mph wind chill factor.
I just get dressed normally with no under layers (No Under Armor shirt or pants) and I slide right into these pants and button and zip them up at the waist, then I put my boots on with the inner liner inside my boots and the outer pant leg outside my boots and I'm ready to put my jacket, helmet, and gloves on and go. A quick, convenient process.
I commute every day if there is no ice. My entire trip is on the freeway. 40 miles up and 40 miles back. I do have a windshield but my legs are totally at the mercy of the wind.
Joe Rocket Ballistic 7. If you need a bigger size in winter only pants, this is your ticket.
