Product description

Be prepared for the unpredictable with our adaptable Ascent™ Series bags.

Light, warm, comfortable and most importantly, adaptable. Offering the perfect backpacking balance of comfort vs weight, our Ascent™ Series sleeping bags have more space than traditional mummy bags, yet still provides the thermal efficiency you need when exploring above the tree-line.

FREE FLOW ZIP SYSTEM

Strategically placed zips offer ventilation options and freedom of movement.

The Free-Flow zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it’s not. The half zip on the right side of the bag (left side on women’s bags) provides freedom of movement for both arms, additional ventilation and also means the top third of the bag can be folded down as a mini quilt when the mercury climbs higher than expected. A separate foot zip on the Ascent, Altitude, Traverse and Venture provides extra ventilation and also transforms the bag into a full quilt.

ZIP COUPLING - ASCENT/ALTITUDE

Down and synthetic bags identified with our zip coupling symbol use a 165cm #5 YKK full-length zip which allows a unisex left-handed and women’s specific right-handed bag to pair together.

Designed to pair side by side, each person sleeps in their own bag enabling each of you to take advantage of your bag’s unique insulation zones, hood and footbox features—perfect for cosy adventures for two. Bags with full-length #5 YKK zips on both sides can also be coupled together with other pairing bags.

750+ LOFT ULTRA-DRY DOWN

750+ Loft

750+ Fill Power indicates that 1 oz of down will re-expand to over 750 cubic inches after compression. Higher loft means that less down can be used to achieve the same temperature rating – important for performance sleeping bags. The loft and down quality/composition are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is supplied with every Sea to Summit sleeping bag.

ULTRA-DRY Down™

ULTRA-DRY Down™ is a permanent nano-level water repellent polymer treatment applied to our down which protects it from external moisture and condensation from inside the bag virtually eliminating the negative effects moisture has on down.

RDS CERTIFIED DOWN

All Sea to Summit sleeping bags use only down which is certified according to the Responsible Down Standard. The RDS is helping shift the entire down and feather industry towards more humane animal rearing and handling practices.

Overseen by the industry leading Textile Exchange, the RDS requires independent, third-party assessments of all aspects of animal rearing and handling throughout the entire supply chain. By using only down that meets the audited requirements of the RDS, we can have confidence that each phase of the collection process has been completed with the welfare and ethical treatment of waterfowl in mind.

EN RATING

The EN13537 is a European standard for sleeping bags that provides three temperature levels to help guide you when choosing a bag.

Comfort The temperature at which a standard woman can expect to sleep comfortably in a relaxed position. If you are female or consider yourself a cold sleeper, use this rating to decide the coldest temperature the sleeping bag is suitable for. We emphasise the Comfort temperature for our women’s specific sleeping bags.

Lower Limit The temperature at which a standard man can sleep for eight hours in a curled position without waking. If you consider yourself a warm sleeper, use this rating to decide the coldest temperature the sleeping bag is suitable for. We emphasise the Lower Limit temperature for all our unisex sleeping bags.

Extreme This is a survival only rating for a standard woman. Between the lower limit and the extreme rating a strong sensation of cold must be expected and there is a risk of health damage due to hypothermia. This is an extreme survival rating only; we do not recommend you rely on this rating for normal use.

FEATURES

The Ascent™ is our sleeping bag of choice for most adventures.

If it’s warmth you’re after, close all the zips, pull the cord locks tight to drag everything in, and relax in luxurious comfort. The generous allocation of high quality 750+ Loft down ensures great insulation, while the oversized draft tubes prevents your body heat escaping. The panelled footbox and 3-dimensional hood make sure you’re not compressing the down when you’re trying to stay warm.
