Montane's Prism Pants are super packable Primaloft insulation that provide instant warmth. The Pertex Microlight outer fabric also provides extra protection against bad weather.

Montane says:


Highly packable insulated legwear than can either be easily pulled on immediately post-exercise to gain a quick warm fix or worn as Alpine mountaineering insulation. They provide formidable warmth for their low weight.

Great pants for cold conditions

I got these because I really feel the cold and didn't want to stop going out in the winter. They are really warm, weigh little enough that I never doubt taking them and they are easy to get on and off. The pack size could be better but I place more importance on warmth over this. They are comfy and have so far proved pleasingly durable around camp and for bothy nights.
