Simple and durable, yet refined, your perfect companion for uncomplicated summer adventures.
Our Treeline™ Sleeping Bag is a budget down bag that is ideal for three season use when you’re confident the temperature won’t drop far below freezing.
600+ LOFT DOWN
600+ Fill Power indicates that 1 oz of down will re-expand to over 600 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.
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.
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.
Light enough for backpacking adventures, this sleeping bag can withstand the rigours of sharing your outdoor adventures with kids or dogs.
Utilising our unique internal cord tunnel in the hood and neck draft tube, the Treeline™’s exterior finish is kept neat and free of additional loose fabric. The internal chest pocket is a great spot for keeping valuables secure, or batteries warm. While we’ve given this design a little extra room around the shoulders and hips for freedom of movement, the relaxed mummy shape still provides efficient warmth and heat retention when you need it.
