Most comfortable; one of the most versatiles. - Western Mountaineering Cypress GWS -30 Sleeping Bag -850 Down-

To begin with - as always, a reliable service from the CampSaver.

Now - the Cypress:

- Can be opened up to make a quilt
- Much more functional than in my Feathered Friends' storm flap for external zipper protection, sideblock baffle and the best stiffening tape along zippers to prevent snags protecting inner material not to be "taken in" and damaged by zipper than in any other bag known to me
- Dual zippers allow bag to open completely around the foot and lay flat - which adds to the versatility (say, allows for different modes of ventilation).

I copy below my review of Rab-1200 - hoping it helps to compare:

"Pros:
- Amazing work kraft
- Cute
- Very durable (Pertex Endurance outer; especially robust drawcords).
Cons:
- Sizing. A tightest bag I ever had - shoulders-hips-feet: 160-126-90cm. No wonder it is more narrow than my semi-rectangular Western Mountaineering Cypress GWS (175-155-122, in the same -30F temperature rating). But - other bags for even lower temperatures are much roomier: say, Mountain Hardwear Ghost -40, L, is: 157-147-101cm; even the Feathered-Friends-Snowy-Owl -60F is 162-152-99cm (but 500g heavier than the Rab). So, Rab is for the circumstances where weight-saving is vital to survive.
- Worms. Most winter sleeping bag temperature ratings assume that you are wearing long underwear including socks, sleeping on a sleeping pad or pads with a high combined R-value, and you are in a tent or bivy sack. Only way I can explain the Rab -30F rating is: with all expedition gear (baselayer, than down booties, expedition down pants, expedition down jacket) when sleeping + to be a "cold sleeper" of high capacity... To put it shorter: my aforementioned WM Cypress -30F is much (much) warmer - of course, being 290g heavier.

No disrespect to Rab production. I own few Rab items (say, Rab Neutrino plus) and they are one of the bests. Rab should've just emphasize the approach to the Rab-1200 better."
