About the Western Mountaineering Summerlite Medium

What is the Western Mountaineering Summerlite good for?

Perfect for those looking to stay warm on summer mountain missions without compromising on weight. It’s designed for fast, light adventures where performance and packability are key.

How will some of the key features of the Western Mountaineering Summerlite enhance my experience?

The SummerLite's impressive combination of warmth, lightweight design, and durability makes it an essential part of any summer expedition kit. The 850+ fill power European goose down ensures maximum warmth while still being incredibly light, weighing only 595 g even in the largest size. The full-length YKK zip offers easy access, allowing you to quickly adjust to changing conditions, while the insulated draught tube prevents heat from escaping, keeping you warmer in cold temperatures. Continuous baffles allow for better heat distribution, ensuring your warmth stays consistent throughout the night. These features work together to provide a sleeping bag that’s both high-performing and incredibly packable, so you can travel light without sacrificing comfort.
