Why oh why did long underwear makers kill the fly?

The only true advantage male alpinists/ice climbers have is the ability to pee without removing a harness. Life is very unfair but I would never voluntarily give up this wonderful gift (and I don't expect to be given the gift of multiple orgasms anytime soon).

So why, in only a few short years, has a fly on men's long underwear gone from 100% standard to a rarity? To my knowledge no Euro brands, or Dead Bird (who do like to "design out" everything) has a fly/opening anymore. Discussing this with other guys, I have been shocked to learn that for some wiggling the little fireman through a fly while wearing street clothes is simply way too challenging of an endeavor (it is not that complicated but to each their own) so many adopt a pull-the-underwear-down move, I guess, which I can theoretically see is easy wearing jeans and a t-shirt inside a warm office bathroom.

But with long underwear and a harness and at a cold ass ice belay, what the hell is the move (and why would you want to) without a fly? Actually, I don't really care about flyless pee techniques, I am more interested to hear who is against and who is for this disturbing trend in male alpinist undergarments.

And for the record, I have yet to climb with the badass lady alpinist who has embraced and uses a Shewee, Freshette, etc. but I sincerely feel for all my climbing sisters on this inequality.

Patagonia capilene has your back (or front I guess) 

IMHO, when you are in a harness, this compromises any real life ability to "wiggle it out" no matter what circumstance, unless perhaps one is hung like a horse and has a lot of extra inches to work with. Something is always compromised, whether it's pissing yourself slightly or a lot. Do we have it easier? Sure, but it's still complicated no matter how you slice it. I guess I've just always found it easier to go "over the top", just like in street situations.

Last I remember Smartwool longjohns have a fly, i also wear an alpine style harness: CAMP Mt Alp, or Singing Rock Jeff Lowe.
I do have a North Face pair of longjohns that doesn't have a fly, but I bought these on the fly (HA!) in Scotland.
It cracks me up to watch joes at the crags struggling  with their mojo because they think they need a full fledged harness.
Hydrate and then pee.

I think your lament is premature.

I find it much more disturbing that you’re taking a piss at ice belays.  You must be a real treat to follow.  

Being able to whip out your junque and pee without fully decoupling all of your outerwear and crouch down is prime cishet privilege. You need to check yourself with that pal.
Standing to pee is oppression and must be banned immediately. Huge fines, jail time, sensitivity indoctrination.
