I had (have) a pair of fulmer and their only problem was (is) if it is above 55 or so, you get too hot.
Last winter I was surfing cabelas and they had a pair of Arctix pants (classic I believe) in clearance, really cheap, and I bought them for fishing.
Love them for the bike.
They are a very light pant plus do a great job keeping you warm, plus when it warms up I don;t sweat to death.
The other day I went for a ride, it was maybe low 60's when I left. I had on a pair of shorts and a t-shirt - I put the artcix pants over them and put on my synergy heated jacket with a ventilated coat.
After the sun went down, it quickly dropped to a cold mid 40's....(cold wind).
Now remember, all I have on is my shorts and the arctix pants........never got the 1st bit chilly. If I was on a longer ride, would have obviously been better with a pair of pants under them, but I did not get cold.....and I hate getting cold.
I am pretty sure these are what I have....and only $20.00. Comments say bad stitching - my pants were perfect. I wear them ALOT and they have held up well.

and again, only $20.00......the fulmers cost me around $80 or so and I never wear them anymore
also, I keep beating this drum......bite the bullet and spend the $211.00 for a synergy heated jacket liner.......you will wonder how you ever rode without it. I shied away for years, thinking it a luxury. Now that i have one, it is every bit as important as my backrest. It literally changes the way you ride as you do not have to layer (I often wear just a t-shirt - no matter how cold) and it is soooooo convenient . We are in the mountains....warm on the bottom, cold at the top.....no big deal and no sweating at the bottom. Starts getting chilly or cold, reach down and turn a knob.
I have now ridden in it when it was 43 degrees out, with the arctix pants) and I could go on a 1,000 mile road trip with ease.
Not a luxury for me now, but an integral part of my ride
