I had a pair of mittens that where my wife's but she never liked them so they ended up in my bag . My way-to-expensive Marmot long-cuffed gloves weren't keeping my fingers warm in the frigid weather we've had East the last week or so so I switch to the mittems. THEY ROCK!!! I'm converted. Mittens with liners are the way to go!!!
I used liners with gloves. Probable is, if the gloves are a good fit without liners, with liners, they'll be to tight and you'll lose precious circulation. If the close fit good with liners, they'll be baggy without.
Using liners with mittens, your fingers are toasting and if you need to fix something real quick, just take the mitten off and you can use your finger thru the liner. Put the mittens back on and in a minute, your fingers are toasty again.
With gloves, if a finger gets cold, it stays cold. So if you have to take a glove off to fix something, you might be screwed. Once fingers are cold, they lose circulation and may not warm up til you go in.
I broke both shear pins in my snowblower cleaning up after the weekend nor-easter. I took my mittens off for a couple minutes to do the work, they were were soaked on the outside and froze hard as a rock. I put them on when I was done fixing the thing and within a minute my hands were toasty warm again.
Enough raving. I'm now a mitten convert.
By the way, the mittens were GCS. I had GCS gloves years ago and was totally unimpressed. The mittens I have now, I love. Like I said, they got soaked on the outside and wear try and toasty on the inside. Something I can say about my way-to-expensive Marmots.
