Technical Features
Sea to Summit Women’s Specific Sleeping Pads:
Built differently from the ground up, to provide women adventurers with the best possible sleep.
Both Air Sprung Cell and Self-Inflating mats have a shape that is narrower at the shoulder, then widest between the hips and knees to permit a natural side or ‘figure four’ sleeping position. Air Sprung Cell pads have more Thermolite® insulation than their Unisex counterparts. Self-Inflating pads have smaller-dimensioned Delta Cores in the hip and foot sections to create extra Comfort and Warmth Zones.
Sea to Summit Women’s Specific Sleeping Bags:
Engineered differently than Unisex models, to provide women adventurers with the best possible sleep.
They have a shape that is narrower at the shoulder, then widest between the hips and knees to permit a natural side or ‘figure four’ sleeping position. Women’s specific body mapping deploys insulation for warmth where it is most needed. Additionally, the Journey and Altitude down bags have a layer of Thermolite synthetic insulation in the footbox to warm your feet more quickly.
Journey, Altitude, and Venture can be zipped into many Sea to Summit Unisex sleeping bags.
The second highest-lofting down used in any of Sea to Summit’s sleeping bags or quilts. 650+ Fill Power indicates that one ounce (30g) of down will re-expand to over 650 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. The down is responsibly sourced and RDS certified and treated with our non-PFC Ultra-Dry Down™ treatment.
Our Free-Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it's not. The half-zip on the right side of the bag (left side on women's bags) provides freedom of movement for both arms, additional ventilation and allows the top third of the bag to be folded down as a mini quilt when the mercury climbs higher than expected.
100% of the down used in our sleeping bags and quilts is independently certified to the Responsible Down Standard (RDS). The RDS certifies down against animal welfare requirements and tracks it from the source to the final product. The purchase of RDS certified products demonstrates demand for better animal welfare practices in the down and feather supply chain. Sea to Summit is certified to the RDS.

Sea to Summit sleeping bags do not contain PFCs.
Ultra-Dry Down™ uses a non-PFC hydrophobic treatment to ensure it absorbs less moisture and dries more quickly. The treatment does not affect the breathability or the lifespan of the down and lasts through at least 20 washings.
The down used in our sleeping bags is RDS-certified responsibly sourced.
Down and synthetic-insulated sleeping bags utilize a non-PFC DWR treatment on the shell fabric for external moisture repellency. This helps prevent the insulation from becoming damp if the sleeping bag comes into contact with condensation on a tent wall, for instance.

Frequently Asked questions
Can Treks be zipped together?
Yes - the unisex and Women's Trek can be coupled (Unisex Trek will zip to most STS Women's bags)
What does 'women's specific' mean?
Narrower shoulders, the widest point at the hips to allow a woman to assume a natural, side-sleeping position, and insulation deployed where women need most warmth.
What are the differences between the Women's Trek and Women's Ascent?
The Trek has a broader cut and is intended for travel/camping/some backpacking. The Ascent is a more technical bag for ambitious backcountry use.
