>>935936Some anons know whats up, modular system is the best. Mine personally is a 500 weight (2 season) down bag, silk liner, s2s thermolite liner and a thermarest tech blanket.
Depending on how hot your summers are, you want to start with a 2 or 3 season bag. Down bags are the lightest and most packable but are expensive, shop around. If you get a down bag, dont use a bivi as your sweat clumps the feathers and youll get cold.
A good liner is a must, cleaning your liner instead of your bag will add years to its life. I used polycotton for a while and its fine, but silk is lighter and warmer. Sea to summit do three weights of fleece liners which are really fucking warm, only used the lightest one but it was really warm, worth the investment.
Down quilts seem amazing, but ive never found one that seems worth the price. Thermarests tech blankets seem more reasonably priced, and are great for hot summer use alone.
The mat is probably the most important part of cold weather camping, as it stops the ground stealing your precious warmth. I personally like lightweight air mattresses, like the thermarest xlite and xtherm. Ive bever used the xlite, my summer mat is a zlite cos its so cheap. I won the xtherm in a comp and honestly its amazing, you can feel the heat radiated back at you. With the xtherm ive taken my system to -25 in norway
This is a system for tent camping, if i was bivying id want a synthetic bag and hammocking id probably invest in the quilt
