Rab says:

The Photon Pants are very warm, PrimaLoft synthetic insulated pants, designed to provide greater freedom of movement in extreme polar environments.

Using a combination of Pertex Microlight and 100% Ripstop fabrics, the Photon Pants are extremely durable and are designed to withstand expedition abuse. Reinforced knees, seat and kick patches provide high levels of freedom of movement, and full-length YKK side zips make the pants easy to take on and off when wearing crampons. A expedition fit means the Photon Pants can be worn as an outer layer in conjunction with the Expedition Jacket in the harshest environments.

Welcome return for the Photon pants - Primaloft insulation is the best synthetic insulation around at the moment - so warm to weight ratio is quite good. The Photon Pants are not built purely for that reason though they`ve got reinforcement areas on the seat knees and inside ankles and full length side zippers for easy on and off over other clothing all refinements that add a bit extra weight.  With so much insulation its hard to recommend these as a trekking trouser - in this country at least you`re likely to be too warm if wearing them while heading up a gradient although the long side zippers do allow some venting if the need arises the zip opens top to bottom or bottom to top. 

They are perfect for slipping on around camp or when stopped for a while.

Very warm pants

Ordered these for the chilly conditions in south Western Australia winter... and for alpine/cross country ski snow camping base camp later on.

Full length zips make them easy to put on over your goretex pants/bib. Nice reinforcements where you need them, so they can be used climbing as well as base camp. Also means wont wet out to easily.

I wear them directly over underwear and it feels like you are in a sleeping bag... actually you could wear them in a sleeping bag and thus carry a lighter bag.

I am 1m84 and the size L is perfect. fits a bit baggy, which may look less cool but is useful for warmth and if you wish to layer them over goretex pants. They have elasticated sides and I use a small nylon belt .

Looking forward to using them evenings around the tent when snow camping, so I can watch the stars without freezing my butt off...
