Summer (0C and Warmer)

When space and weight are at a premium (think biking trips, kayak treks, and epic backpacking), you want a super packable, stuffable sleeping bag that'll fit into sterns, bike panniers, and bags. You need the lightweight, PFC-free, mummy-style NanoWave 45 Sleeping Bag to keep you comfortable around 45°F. Synthetic SpiraFil High Loft Insulation will keep you warm even when things get wet. The full-length zipper wraps around the footbox for easy ventilation. A snagless draft tube prevent air from sneaking in and fabric from catching.

Tempo™ blends roomy comfort with NEMO’s space-saving Spoon™ shape for a relaxed, crowd-pleasing fit that packs smaller than a rectangular sleeping bag. With a generous cut at the elbows and knees, side sleepers can shift positions comfortably throughout the night. Insulated with synthetic Stratofiber™ fill, Tempo offers the best blend of moisture resistance, comfort, packability, and affordability. An integrated pillow pocket allows a jacket, extra clothes, or Fillo™ to be stuffed into the sleeve opening for extra comfort, while the Blanket Fold™ draft collar provides extra tucked-in comfort and temperature regulation mid-season. Left-sided zippers on the men’s and right-sided zippers on the women’s bags allow two Tempos to zip together for a double version of these favorite sleeping bags.

The Cinder is a lightweight, super-packable quilt protected by a waterproof yet breathable shell. A drawcord pulls the foot end together into a foot box for cooler nights, and three adjustable straps keep the quilt secured to your sleeping mat. Quilts are perfect for weight-conscious backpackers. The lack of a zipper and hood reduces weight and packed volume, and the broad cut provides freedom of movement. Sea to Summit quilts feature the QuiltLock system which allows quilts to connect to a Sea to Summit sleeping bag adding an extra season of warmth.

An Ember quilt can be an ideal light and packable option for bikepackers, ultralight hikers and travelers. Constructed using high quality 850+ loft Ultra-Dry Down and featherweight fabrics, this well-constructed quilt offers freedom from the weight of a sleeping bag zipper and the freedom from the constrictive shape that comes with some sleeping bags. The Ember Series takes the simplicity of the quilt concept a step further - snap-on attachment straps keep your quilt located on your sleeping mat, while the drawcord base of the 50°F and 35°F give the Ember a shape-shifter' function: wider at the base for more freedom of movement when it's warm, snugged down when it's cooler. Embers also add multi-season functionality: the QuiltLock system allows an Ember to be attached to any hooded Sea to Summit sleeping bag to boost thermal performance in colder weather.
