India’s Hymalayas trekking questions! Please help?

Question

I'm trekking in the Hymalayas this summer we will max out at about 4800m. i wear base layers on there own and i use the HH cool ones a lot but i dont think it will be warm enough. Is it worth investing in slightly warmer base layer tops to wear for walking during the day. If so please tell me which ones.

Answer 1

slightly warmer base layer tops ok.  Anyway, you can have further more details here at the entrance.
