UOG TOP PICK—The Sea to Summit Ascent is a lightweight sleeping bag ideal for three seasons. Its 750+ fill power of responsibly sourced duck down provides warmth and is treated to maintain performance in damp conditions. It is a fantastic all-round bag for trekking or fast and light, and it is one of our top picks.

Sea to Summit says: 

The Ascent Sleeping Bag is the most versatile in our sleep range and is suited to a multitude of climates, conditions, and adventures. From long distance hiking to weekend getaways, the ultra lightweight 750+ FILL Power offers added warmth
in cooler climates while the Free Flow Zip System allows for added air flow and ventilation in warmer climates. Putting comfort and adaptability at the forefront, the Ascent Sleeping Bag is a premium option for versatile adventures.

Our Verdict

The Sea to Summit Ascent is a versatile and lightweight down sleeping bag ideal for cooler, 3-season overnight conditions. With an EN comfort rating of -1°C (30°F), it provides just the right amount of warmth for nights hovering around freezing.

Premium 750+ fill power responsibly sourced duck down gives the Ascent an impressive warmth-to-weight ratio. The down insulation is treated to maintain performance if the bag gets damp from condensation or light precipitation.

The Ascent's free-flow zipper system regulates ventilation and makes it adaptable. On warmer nights, you can open the entire side zipper or cinch it down to take advantage of the full mummy shape when temperatures drop below freezing.The relaxed mummy fit is tailored specifically for women, offering increased thermal performance with a wider hip area and narrower shoulder cut.

Other key features include a spacious, relaxed mummy fit, adjustable drawcord hood, waterproof, breathable shell over the hood/foot box, and draft tubes to prevent heat loss.

The Ascent packs down remarkably small yet still hits its -1°C rating when fully cinched - making it ideal for ounce-counting backpackers. Just bring extra insulation if you anticipate nighttime lows much below freezing.
