Parsec 20 Sleeping Bag - White Heat

£243.75 RRP £375.00 In Stock

Brand: Thermarest

Model: Parsec 20 Sleeping Bag - White Heat

SKU: 71473

The Parsec 20 Sleeping Bag from Thermarest is incredibly soft and warm, perfect for keeping you toasty on chilly nights in the wilderness. The Nikwax-treated goose down repels moisture to retain loft, meaning you stay insulated even in damp weather, while the Thermacapture™ lining stops your radiant heat escaping for even greater warmth. The Toe-asis™ Foot Warmer Pocket quickly warms your feet for instant cosiness, which is especially welcome when long hikes have your feet feeling frozen! Low-weight at only 890g, this bag is the ideal trekking companion.

NikWax Hydrophobic Down™ is a safe, high performance, fluorocarbon-free water resistant down fill for outdoor insulating clothing and gear. It resists getting wet, so the loft and insulation properties of your gear are maintained and you stay warm and dry.

ThermaCapture Radiant Heat Technology is a proprietary reflective coating that we apply to a range of surfaces. By reflecting radiant heat back to your body that is otherwise lost, this extremely lightweight coating turns that surface into a very efficient heat reflector, amplifying warmth without the excess weight or bulk of added, conventional insulating materials.

Integrating mattress and bag, SynergyLink™ Connectors make sure you stay on your mattress while you roll freely for the best nights rest possible. Two elastic bands create a snug fit around any mattress up to 25 inches (63.5 cm) wide, keeping your bag centered and eliminating problems with sliding off your mattress or getting your bag twisted around you.

Zoned Insulation puts loft where you need it most – on top of you where it traps rising heat. Beneath you we use less fill, where your mattress already insulates you, and the value of lofted insulation is already minimized by compression. This is possible because our sleeping bags integrate with your mattress, keeping it properly oriented to maximize warmth and save weight.

Toe-asis™ Foot Warmer helps to rapidly warm cold feet, offering a baffled pocket of insulation in the footbox of our Women’s down and synthetic sleeping bags. Just slide your feet in for maximum warmth. Leave them out and you’ll still benefit from an extra layer of insulation in the foot of your sleeping bag.
