Hiring of Jackets/ Boots/ Gloves

Hello psatishmenon,

Please be patient (see the forum rules); your post was on the forum for less than 24 hours. Everyone will get an answer here. As for your question: if you're planning a normal visit to these places, it's my experience that multiple layers of regular clothing, plus sun glasses, is good enough. If you plan to be outside for a longer time or do activities in the snow, then indeed you need better clothing. For the Titlis, see this topic. For the Jungfrau: you can contact the Intersport shop in Interlaken. I know they rent out gear, but you can best contact them directly for the exact options.

I hope this helps you out. Have fun up there!
