Yep - get a couple of sizes. They're free, after all.
For what it's worth - I'm wearing the Burton Powerstretch liners (underglove) under my 720s in the video. Cushy and warm... Like a thick sleeping bag on a cold winter's night - except with all the dexterity of a surgeon's glove.
Water temp was 60.8 degrees F... Frankly, a little warm for undergloves with the 720... But I was laying in the mud for over an hour making that cut, so why not be super cushy?
I swear, I'm getting pretty spoiled in this setup. For something like 15 years I ran this company in a wetsuit, diving year-round... Sometimes in waters as cold as 35° or so. Man, technology is a wonderful thing...
Best part is cleaning up... I hose myself off while wearing the suit, and that's pretty much it. Step out dry and warm. Hang the suit. Simple. Years ago, every day I would strip down to a bathing suit on the dock - often in 40° or 50° air - and hose myself and the wetsuit... Front and back, inside and out. Twenty or thirty minutes in the cold, wet, unforgiving winter air, wearing nothing but a wet bathing suit... Mostly, because I could not get a drysuit to seal at my wrists - and drygloves were out, as I holed them every dive.
No longer is that the case. I can trust my drygloves - and I'm actually dry inside the suit! Crazy technology!
For me, the 720s and the Waterproof Ultima Dryglove Ring System changed everything.
