Sea To Summit Treeline TlI Long

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.

• 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.

• 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.
