Gear Review: Nathan Transwarmer Convertible Mitt

The Problem

I live on the East Coast of the US, and it is Winter. If you live in this area, you know that this year has been exceptionally cold. I’ve been having a hard time this year with gloves and keeping my hands the right temperature during runs. I have thin gloves that breathe, but my hands can’t seem to stay warm enough in those, even after running a few miles and the rest of me is nice and warm. I have thick gloves, but those don’t breathe, and my hands sweat in them and get too hot, then I end up taking them off and my hands freeze even more.

The Solution

Last week I saw what I thought might be a solution for me. I’ve been reading that mittens are best when running in temperatures below freezing, because they let your fingers stay together and huddle for warmth. I found the Nathan Transwarmer Convertible Mitt on sale, and thought, for $12, why not give it a try.

The gloves look great. Best of both worlds, I thought. Gloves when you wan them (with touch-screen fingers) and mittens when you need them. My box arrived with my mittens yesterday, and I gave them a try this morning.

The Verdict

It was 20 degrees Farenheit (about -7 Celsius) when I went out to start my 12-mile run this morning. I started up RunKeeper and slipped on the Nathan Transwarmers in Mitten Mode right off the bat. Brrr it was cold! My thumbs started getting cold right away, so I tucked them into my fist to keep them warm. All was well until about 2 miles in.

Just after my 2nd mile, I noticed that my hands were getting sweaty. And while the glove part of the Nathan mittens is “moisture wicking” the mitten shell is not. So my fingers were getting progressively wetter under the mitten shell, and getting progressively colder. I decided to take the mitten shell off for a while an see if the gloves would dry. The air is very dry and I hoped that the moisture would wick off and I’d be okay. I was wrong. The moisture on my gloves instantly started to freeze. My hands were not warm enough to stave off the freezing with temperatures so low. So I popped the mitten shell back on my partly wet, partly icy fingers and kept trudging on. I started putting my hands, gloves and all, into my pants pockets to try and glean some of the ample warmth coming off of my quads. That helped, but my gloves still wouldn’t dry.

This was bad. I had a lot more running to do, but there was no way I could keep going with wet gloves on such a cold day. My fingers were starting to get numb. Thankfully I was running near home today. I changed course and made a loop back to my house, and reached it about halfway through my run (6 miles, 1 hour). I popped in and changed out my gloves for my really warm, thick gloves. I don’t even know what brand these are. I bought them from a small, local vendor at a race expo last year. They are the ones that usually make my hands too hot, but this time they were perfect. My hands were so cold, my fingernails were blue, so when I got them into my warm, thick gloves, they were finally happy.

I’m happy to report that I was able to finish the rest of my run with very comfortable hands.

As for the Nathan Transwarmer Mittens, from me, they get a FAIL. I’ll be getting a refund on those for sure.
