I've taken the Sherpa 50 with me glamping, up Denali, and other camping trips. I've used it to charge GoPros, walkie-talkies, and my iPhone 5 with the USB port, and have used the inverter to charge my boot heaters and Canon G10, and to power my Mac Book Pro and a Nespresso milk frother (It wouldn't warm the milk due to the high draw of heating elements, but it gave a nice froth).
This is a very warm mitt when both the liner and shell are used. The times I've used them have been for summit attempts on Denali, hanging out at 14 camp of Denali when the sun goes down. Very cold times, and my hands were nice and cozy. I wear a size 10, and would wear a large in regular sizing.
The Hero3+ Black is hands down the best camera in its class. Photos and video are noticeably sharper than the Hero3 Black, battery life is longer, the wifi is faster, low light shooting works better, and the continuous photo mode is one of my favorite new features. With continuous photo, you can change the number of frames per second you choose to shoot (1,3, or 10 I believe), and then you can hold down the record button for up to 30 seconds and capture action the entire time.
Camera aside, the GoPro App and GoPro Studio 2.0 give tremendous support.
Favorite features on the App:
Being able to change all the camera's settings and modes on one screen.
Saving photos or videos to your camera roll and instantly uploading to insta.
Being able to see what the camera is seeing.
Remotely hitting record.
GoPro Studio 2.0- An easy to use editing platform.
Studio "speaks GoPro," which means video playback is easier and more continuous than just watching it straight off your drive.
Selecting ins and outs and exporting just the parts of your clips that you want.
Full resolution screen grabs is a big bonus- maybe you didn't stomp that 60 footer and ruined the video... just export the sickest frame, and count it!
I see a lot of complaints about people's cameras being glitchy (not on the Hero3+), and have found that as long as my firmware is the most recent version, I have zero problems.
I like the easy to open/close vents and the hard plastic shell for when I'm climbing lines that may have exposure to rockfall. The Maze and other ultra light helmets are nice and light, but don't vent as well, and seem like they might not stand up quite as well to rockfall or falling on rock. Comfort is good, venting is great, Smith I/O or I/OX integration is a big bonus, and the ability to zip the Skullcandy headphones into the ear covers is nice too.
I'm 5'9", 190 lbs, and would say that this board can handle anything you can put in front of it. I rode the 164 Carbon Flagship all 2012/13 (probably 80 days on this board), including in all 6 stops of the Freeride World Tour, in Haines, AK, and wouldn't have felt as confident on any other board. Stiff, durable, and reliable, this is your board if going fast in big terrain is something you enjoy. It rides great in pow, chopped pow, groomers, chalk, and corn, but isn't a super fun board to ride firm moguls on.
The first run of this vid was an early morning tour on the 164 Solution with Karakorams. This split setup rides like a solid one-piece snowboard. Backcountry.com's recommended use is correct (big-mountain, charging spines); it's a stiff board that will perform if you ask her to.
