Sea To Summit Flame 3 FMIII Women's -4c

The versatility of the Flame Ultralight Women's Sleeping Bag Series spans from an ultralight down-filled liner to a mid-winter fast-and-light sleeping bag. Each model uses premium materials and design to provide cutting-edge performance.

The women's specific mummy fit is narrower at the shoulder and wider at the hip, and features extra down compared to the unisex Spark models.

Shaped for comfort

Narrower at the shoulders, wider between the hips and knees. Regardless of the position you sleep in (figure-four, on your side or on your stomach), this shape provides a significantly higher level of comfort by giving you the room to move without compressing the insulation.

Warmth from additional insulation

Additional insulation compared to unisex bags, positioned using different body mapping for thermal performance exactly where it is needed. Temperatures for Women’s sleeping bags are shown using the gender appropriate Comfort rating.

Maximum comfort for a good night's rest

Construction details like snug-fitting hoods and oversized draft tubes keep you warm in cooler weather. Super-soft fabrics are comfortable in any season.

You don’t have to narrow your options with a constrictive mummy bag – expand your horizons with a sleeping bag which fits the way you sleep.

Functional, lightweight and warm

I bought this bag to replace my other sea to summit talus 2 that was about 8 years old. I thought I could go lighter.
The flame 3 was recommended by Dave Parker.
It's about half the weight and pack down size for the same warmth rating.
I'm 75kg, 173cm in height male, and was initially a bit hesitant on getting the regular size.
After two days on the west coast of the south island in new Zealand, where temperature dropped to below 4, I'm convinced this bag is the right choice.
Things I really like about it
-how light and packable it is. You have to see it and feel it in your hand to truly appreciate it. It's amazing.
-the verticle baffles, they make a big difference in reducing cold spots. Certainly a nice feature on those frosty nights.
-the simple draw cord to close the hood. Can't mistake it in the dark because there's only one.
-the sizing. I'm a perfect fit length wise for the bag, and it's got plenty of room in the shoulders, unlike some of the other ultra light mummy bags I've owned.

Great sleeping bag

So far just the one nights use, but spent a very cozy night just above 0C, can’t fault this bag.
