The micro-weight 10D nylon shell and the 15D lining ensures that your bag stays dry & warm - wherever you are.

A box-wall baffle construction is utilised for heat retention and the head/neck baffles have been enlarged to trap vital warmth. The Spark is filled with 850+ loft ULTRA-DRY Down (90/10 European Goose down) insulation. The shell is built from an ultra-light 10-denier nylon that has been treated with a DWR (durable water repellent) finish. The soft-touch liner is a high-density weave, 15-denier nylon.

There are many factors that affect your warmth and comfort in a sleeping bag. An important factor is that you use a good insulating mat to prevent your body heat from being drawn into the cold ground.
Other factors include your tent or shelter, gender and metabolism, clothing, sleeping bag liner, use of the hood and your daily calorie intake. Although the EN13537 standard does not identify a single precise temperature a tested sleeping bag is suitable for, it does provide an industry standardised temperature range that a typical user can refer to as a guide for the conditions their bag will be most comfortable in. The EN13537 standard provides three temperature levels to guide a consumer in their choice: COMFORT The temperature at which a standard woman can expect to sleep comfortably in a relaxed position. LOWER LIMIT The temperature at which a standard man can sleep for eight hours in a curled position without waking. The EN13537 temperature tests use a thermal manikin with heaters and temperature sensors to measure the insulation value of a sleeping bag.This manikin is wearing one layer of long underwear and is placed inside the sleeping bag on an insulating mat. The test is conducted in a temperature controlled chamber and a range of comfort temperatures are derived from measuring the energy required to maintain homeostasis in the manikin to a set temperature. All Sea to Summit sleeping bags have been tested to the EN13537 standard. We recommend you use our EN13537 quoted ratings as a guide and a comparative reference to other EN13537 tested bags.
