Mountain Equipment Klimatic III

This bag is rated for 21 degrees Fahrenheit. It is designed for cooler conditions, making it a solid choice for shoulder-season backpacking or high-altitude trekking where temperatures hover near or slightly above freezing.

The Alpine fit is a tapered, mummy-style cut designed to minimize dead air space inside the bag. By keeping the insulation closer to your body, it maximizes thermal efficiency, though it may feel more restrictive than a rectangular or semi-rectangular bag if you prefer to sprawl out while sleeping.

The Klimatic III accommodates users up to 78 inches, or 6'6", in height. If you are 6'4", you should fit comfortably with a little room to spare at the foot-box.

The 90% recycled POLARLOFT synthetic insulation is highly durable and retains its loft and warmth even if it gets damp, which is a significant advantage over down in wet or humid environments. It is also easier to care for and clean than down.

Yes, it is equipped with a full-length zip baffle and an integrated collar. These features are essential for sealing in warmth and preventing cold air from leaking through the zipper or neck opening during the night.

At 2.69 lbs, it is a respectable weight for a synthetic bag with this temperature rating. While it isn't as ultralight as high-end down bags, it offers a reliable, low-maintenance balance of weight and warmth for most trekking applications.
