Trek 2 TKII ATk2 Down Sleeping Bag. The Trek-II by SeaTo Summit delivers traditional comfort and value, with an anything but traditional design approach, the Trek Series sleeping bags are ideal for globe-trotting adventures on a budget.
Vertical baffles over the chest section ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation. Lightweight fabrics reduce weight and packed bulk while the two-way #5 YKK full length side zip and separate foot zip, allows the bag to open out completely and double as a quilt.
The foot zip is perfect for extra ventilation or to provide freedom of movement for your feet. The 3D side-wall baffle ensures that down can loft to the very edge of the bag, maximising insulation, while the paneled hood draws in tight when needed or lies flat for use in warmer weather. The oversized zipper draft tube uses anti-snag materials to prevent the zipper catching and the soft-touch 20D lining fabric is highly breathable yet also down proof. Completing the thoughtful design features of this classic down bag, we have included a large internal security pocket, perfect for keeping valuables close or batteries warm. 30D Nylon shell and soft-touch 20D Nylon lining fabric provide extra durability while still offering good compressibility.Super-compressible and lofty RDS 650+ Ultra-Dry technical Down insulation.

ULTRA-DRY Down is a permanent Nano-level water repellent polymer treatment applied to our high loft, high quality down.The Nano-thin treatment vastly improves our downs reaction to water without effecting its weight or loft performance. ULTRA-DRY Down retains over 60% more loft and absorbs 30% less moisture when compared with untreated down. Sea to Summit sleeping bags dry out 60% faster than bags with untreated down.
The Nano-level treatment also inhibits bacterial and microbial growth, which makes Sea to Summit sleeping bags more hygienic and improves their lifespan. No loss of treatment effect has been seen in over 14 wash cycles. 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.
