1) You appear to be wearing plenty of layers in your sleep system that on paper should keep you warm at the temperature stated. So that would lead me to believe that you were getting cold from the ground and that your sleeping pad is not sufficient enough.

What sleeping pad are you using? Which shelter are you using?

2) Typical 4-5 day trips I will pack the following:

- Down vest
- Insulated bottoms (depending on forecast)
- Capilene 3 (for sleeping or providing addition warmth or to wear wile washing my first baselayer)
- Ankle socks (to sleep in or to wear while I wash/dry my hiking socks)
- Windshirt
- Raincoat
- Rain pants
- Warm hat
- Warm gloves

No 2nd pair of underwear and no heavy 2nd pair of hiking socks.

3) For rain I have two forms of protection. My windshirt and my rain coat-- I mainly use the former unless it is a heavy, prolonged downpour. The Marmot Ion is perfect for shedding those summer storms. I also have Golite Reed rain pants which for an extra 5.8oz I don't mind throwing in the pack.

As for pack protection, I use a trash compactor as a pack liner. Weighs 2.4oz-- much better protection and lighter than a pack cover.

Cooking in the rain-- use your tent vestibule. I only cook for dinner and thus in the evening I am at camp, with the tent or tarp set-up.
