Sea to Summit Treeline TLI Sleeping Bag (Regular)

Simple and durable, yet refined, your perfect companion for uncomplicated summer adventures. The 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. Light enough for backpacking adventures, this sleeping bag can withstand the rigours of sharing your outdoor adventures with kids or dogs. Utilising a 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.

Treeline Sleeping Bag Features:

• Internal chest pocket is perfect for keeping valuables secure, or batteries warm
• Supplied with stuff sack and storage cell for compact storage
• Zip Coupling: this bag is designed to pair with another
• RDS Certified Down

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. 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. 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.

600+ Loft

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.
