Regarding bivouacs, the answer was already given. I just add data on current conditions. I was on Jalovec yesterday (16.7.) from Tamar to Kotovo sedlo and then descent via Mali kot or Jalovška škrbina or whatever you call it.

On the ascent, you need to cross a gully, where there's still quite a bit of snow, but the snowfield can be bypassed on the upper side. On the descent, there's still a lot of snow on Jezerci. Ice axe is essential for crossing, crampons for faster and safer crossing. I didn't try climbing rocks above the snowfield. Maybe possible. Don't know. On descent from Goličica wall there's still some snow where ice axe is recommended but not essential. Belays from Mali kot are fine. Just watch out for quite a lot of scree on the rocks. Then crossing Ozebnik. It's only about 4-5 meters total, but steep, snow hard and if you slip, you stop at the rock where the path over scree branches off or at Kotovo sedlo.

So ice axe is still mandatory for safe downward crossing, crampons recommended. At the transition from wall to snowfield, a bit of climbing needed. After this snowfield we haven't finished with the snow yet, as there's a smaller and a longer snowfield waiting, but snow was much softer there and ice axe just recommended. Between the two snowfields there's a smaller ridge which technically would pose no problems, if not for huge amount of loose stones which are far from stable. After those snowfields, descent on not ideal scree. On the "competing" forum (hope no censorship if I say it's PZS forum) it's said reverse variant is better. Mali kot up and Kotovo sedlo down. Agree. I think ascent on snowfields much easier than descent. And one more: this year around Jalovec much more snow than last year at same time.
So if you're at least medium experienced hikers, go ahead boldly. Better Mali kot up though ascent on scree quite nasty. Good luck.
