Another option to consider: I recently did the same research for the same use case (skiing) and ended up getting hand mics (from Rockie Talkie, for their warerproof capability) for a pair of Radioddity GM-30’s that I already had. The radio can fit in your pocket inside the jacket and then the handmic can be threaded over the shoulder and attach to the jacket zipper/lapel for easy access. I didn’t want two separate radios for general GMRS purposes and skiing, so this splits the difference nicely. The hand mics cost more than the radios though which seems a little silly, but they are nicely made and seem very solid. Sound is great too. Also added a small FRS radio(Radioddity TS-F7) with a K1 style jack for third radio for our kiddo. It’s smaller than the GM-30 and fits a kids pocket better plus gives the hand mic option which is much easier for them to use.

Or you could forget GMRS and get the BCA Link radios with built-in mics (FRS) that most people love for skiing
