Western Mountaineering MegaLite 30°F Sleeping Bag – Navy Blue, 5ft 6in, Right Zip

Overview

The Western Mountaineering MegaLite 30° sleeping bag is cut for comfort without excess weight. Sized at 5 ft 6 in, it offers a generous shoulder girth that tapers to a snug foot area, letting you move freely inside a compact, lightweight shell in navy blue.

With 12 ounces of goose down, this bag balances warmth and carry weight, delivering a practical 30°F rating for mild to cool nights. The result is a soft, cushioned sleeping surface that feels supportive after a day on the trail.

Design that adapts to your needs

Continuous baffles and 5 1/4 inch spacing let you adjust the fill along the bag to suit temperature shifts or your preferred level of insulation. A full-length #5 YKK zipper runs the length of the bag, paired with a top collar to minimize drafts and preserve warmth where you want it most.

• Full-length zipper with top collar to seal warmth
• 4 inch loft and a 30°F rating for versatile warmth
• 5 1/4 inch spacing with continuous baffles for even fill
• 64 inch shoulder girth tapering to 39 inch foot girth for comfort
• Lightweight build at 1 lb 7 oz total with 11 oz down fill

Packability and practical use

When packed, the MegaLite compresses to a compact footprint and rides neatly in a small pack. The XXS sack and a 6" x 12" stuff size make it easy to stash alongside cycling gear or climbing kit, while the mummy cut supports a secure, wrap-around feel without feeling tight in the shoulders.

Real-world comfort and versatility

This bag shines on summer bike trips, hut-to-hut treks, and camp nights where space and weight matter. The combination of warmth, a roomy fit, and a light touch on the trail can make late-season adventures more enjoyable, yet it remains ready for a variety of warm-weather lodging situations.

Note: While the MegaLite emphasizes warmth and lightness, the actual comfort depends on your sleeping setup, climate, and personal tolerance for cool nights. Consider local conditions and your preferred sleep layer when planning what to bring.
