I tried the Louis Garneau leg warmers tonight for the first time. They worked great. The wind was cutting through my L/S jersey and base layer but my legs were very comfortably warm the whole ride. Whatever they use to block the wind just works. It was chilly for SoCal this evening.

I have two pairs of nashbar leg warmers. They're probably my best value piece of gear - bought them almost 10 years ago for $20 a pair and they're still fine. They're good down to about 45F, below that they start getting a bit cold and tights are a better fit. I haven't had any issues with breathability, they're thicker than bike short lycra but work well.

I ordered some pearl izumi ones of amazon for $25 or so and they work great. Just put them under the shorts and make sure they are nice and high and they won't slip, I've had them on for 4+ hour rides and no slippage. If you get up and walk around a lot off the bike sometimes you have to adjust a little though.

My massive guads make everything seem tight ;). I really like the jelly band on the top. Although they can stretch a bit and loosen between washes, this has always kept them exactly where I want them.

Not common but it can happen. My wife does all her shopping at goodwill. She would no more think of buying retail than putting a bullet in her head. My wardrobe is filled with 100 to 200 dollar shirts and sweaters bought for under 10 dollars that appear virtually new. It takes patience but it can be done. For her the thrill is in the hunt.

I've never tried a pair that stay put. For me, it's embro + summer shorts if cool, embro + knickers if its cold, or tights if its freezing.
