With every Sea To Summit bag includes a “Down Batch Test Report” analysis certificate from the International Down Feather Laboratory (IDEL) to certify the superior loft of the down used in our Sea to Summit sleeping bags. You can be sure of the quality and fill within each bag. Incorporating our 2D PermaShell fabric and a premium 650 loft down, the Trek bags are a refined classic. The 60/40 fill ratio in the Trek bags is maintained using a side block baffle and differential cut shell. In the top of the shell a 3D side wall, a feature normally reserved for technical alpine sleeping bags, provides more space for the down to loft right to the edge of the bag. An oversized security pocket located inside the bag is easily accessible, ideal for stashing passports and other valuables while travelling. The soft touch lining fabric is down proof by construction and highly breathable offering a comfortable sleep. Tapered rectangular sleeping bags. The tapered rectangular design offers a good compromise between the comfort of a generous cut shape and warmth of a closer fit. A full length side and foot zip allow the Trek series to be opened out into a full duvet for use indoors and warm weather. Sometimes a mummy bag doesn t fit the bill – a bit too snug, a bit too constricting. For those who like the extra space and versatility of the classic tapered rectangular shaped sleeping bag, we have created our Trek series but given it our top-of-the range pedigree. 2D PermaShell fabric used in our Trek series bags is a high-density weave, 33 denier Nylon with a DWR finish. This material is highly vapor permeable and down proof by construction therefore it does not rely on coatings. Fabrics Lining 650 Loft Series. The lining material is a high-density weave, 40 denier nylon. This fabric is engineered for comfort using a high filament count to achieve a soft surface and silky hand feel. All Sea to Summit sleeping bags use YKK zips. The Trek series use YKK #5 reverse zips, this allows you to un-zip the sleeping bag from top and bottom for temperature regulation. Trek bags are fitted with a fixed zip length for all sizes. These bags can be zippered together in any combination of model and size. Neatly hidden in the draft tube is a super high-density 210D poly cloth. This fabric is exceptionally stiff and was originally engineered for use in high performance race sails. The lightweight, durable, stiff finish provides an excellent zipper anti-snag. The Trek series use a 2-Dimensional cut. These hoods easily pull into a form fitted profile using the dual-adjustment drawcord. Around the perimeter of the hood an internally constructed drawcord tunnel ensures the cord is buried deep within the down. When drawn closed the hood forms a comfortable seal around your face. A low profile Nifco dual cord adjuster is used for comfort and durability, offering a versatile fit. The hood closure uses a non-stretch cord for refined adjustment, while the neck collar uses an elastic cord to stretch with you as you move in the bag. A large Security pocket is located inside the chest area, it can fit a passport and wallet or be used to stow your electronic devices. Anti-snag coupled with a YKK Invisible Zip ensures an ultra low profile for comfort against the skin. Differential Cut Shell & Lining. Down insulates best when it is uncompressed and fully lofted. To help the down loft correctly, we use a differential cut shell and lining. The top shell of all Sea to Summit sleeping bags is cut larger than the lining. This creates space in between for the down to loft fully. In addition we use 3D side walls which gives the distinctive vertical sides to our sleeping bags, this further aids vertical loft along both sides of the bag. In the bottom of the bag, we use a reverse differential cut. By increasing the size of the lining relative to the shell, down lofts up to fill the voids around your body, torso, legs and the small of your back. Trapping heat close to the skin is essential for efficient warm sleeping. Offset baffle construction provides a stable structure that allows the down to loft to the correct density and minimizes loss of heat through seams. This improves thermal efficiency of the sleeping bag without adding unnecessary weight of complicated baffle construction. Side Block Baffle & Fill Ratio. The loft is optimized using a side block baffle construction which allows the bags to be filled with a different ratio of down in the top and bottom. We have put more down in the top of the bag where it is most effective as the down isn’t compressed by your body weight. The exact ratio of down fill must be matched to the shape of a sleeping bag. The Trek bags a 60/40 fill ratio is more suitable. These bags are a generous cut and have room inside to rotate without the bag following. In a world of technical brilliance it is remarkable that the performance of certain natural products have not been surpassed. Despite advancements in modern fibre technology, down is still the best insulator warmth for weight. Down forms the lightweight undercoating of birds, insulating them in very cold environments. The down we use is a by-product of the duck and goose meat industry. Like most natural products, down quality depends on many variables; predominantly the species, the feather content and the age. The best quality down is sourced from older birds, consisting of large plumes and clusters that create hundreds of thousands of tiny pockets, trapping body heat to provide unmatched insulation. Not only does down have the best warmth to weight ratio, it is also the most durable sleeping bag insulation. If kept dry and occasionally washed using the recommended method, it will last a lifetime. Loft is a measure of volume for a given weight of down. It is used to describe the quality of down, relating directly to the insulating performance. High loft down is warmer for a given weight than low loft down. Higher lofting down will fill a larger volume of space for a given weight, as a result, less down weight is required to fill each baffle in a sleeping bag. This translates to a lighter sleeping bag. The most common measure of loft is called Fill Power. 650 Fill Power implies that one ounce of this down will loft to fill a volume of 650 cubic inches. 650 Loft Duck Down. In the Sea to Summit Trek series, our 650 Fill Power duck down is a high quality insulation that sets the benchmark for sleeping bags in its class. All of our 650 Fill Power down is tested in accordance to the IDFB standard. EN13537 is a European standard for sleeping bag temperature ratings. Everyone sleeps differently; some people are very warm sleepers while others feel the cold easily. 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, so your body heat isn t drawn into the cold ground you are sleeping on. 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 standardized 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. The temperature at which a standard woman can expect to sleep comfortably in a relaxed position. The temperature at which a standard man can sleep for eight hours in a curled position without waking.
