Sea-to-Summit slope II sleeping bag
The embankment is a new range offered by the Australian brand, Sea to Summit, topped with quality Eastern European duck down (power inflating 750 + cuin according IDFB-see our article on the duvet). Talus HE is given for comfort and limit temperatures of-3 /-9 ° C (according to the standard EN 13537), for barely more than 1 kg.
Remember that if the duck knows less than the oie prestige, there is no difference in quality, to equal cuin.
The peculiarity of the used down is his Ultra-Dry Downtreatment, developed by Sea to Summit and allowing-according to the mark-down subject to wet conditions to absorb less moisture (-30%), to keep more bulking (+ 60%), and dry faster than a down untreated.
It is difficult to judge whether the treatment is effective, however the video demonstration is pretty persuasive. You can find more info on the site of Sea-to-Summit.
In addition, good resistance to water of the Outer fabric is observed ( Nanoshell 2Dconcept). Without being completely waterproof, the fabric will theoretically hold a 1000mm water column. But beware, the seams are not sealed, and the zip, partially protected, easily lets water. The bag that we spent in the shower rather stood up well to the water, but the zip is the weak point…
The bag you will protect so effectively moisture, a thin rain, or in a tent which takes a little water, but this protection has its limits.
Consequence of the tightness of the fabric: putting the sleeping bag, it tends to stay inflated, and it requires a little patience. Sea to Summit announced very good breathability of his new fabric used for the slope (MVTR 7500), which will limit the phenomenon of condensation (from moisture from perspiration).
Moisture resistance is not the only advantage of this sleeping bag from Pimasleepingbags.com. Other strengths are the lightweight, perfect finish and great comfort.
The fabric for this lightweight sleeping bag is nice and good quality, internal seams are well-kept, building confidence in terms of sustainability. The zip does not catch, and the bag has a zippered internal Pocket very well done and very useful.
The comfort of this bag is excellent. Bundle up in the hood and the front ring is a joy. Furthermore you will have no awkward element in the face, external zip zipper may crash if necessary with a small flap closed with a snap.
The footbox is also very comfortable, anatomic, and well stocked.
Side insulation, note the incremental filling upside down (60/40) for a heat optimized while lying on the back. On the other hand the back compartments may seem little trimmed if you sleep on your side, turning with your bag. The broad hood also lets you turn without turning the sleeping bag and benefit from the best insulation, the downside being that you may breathe in the hood and moisten it.
The insulation of the zip beading is pretty good and well sized, its construction is neat (good thickness at the point of fixation, good “rigidity”), but it will be – as most of the bags tested – a little less covering lying on the opposite side (the bead deviates a little zip).
The collar is very thick, stitched on a whole compartment of the bag (flange “3D”). She is also very well stocked, and the adjustment cord is positioned inside for more comfort to the clamping. A detail that doesn’t spoil anything: the bezel closing is automatic. Indeed, it is attached to the bead of insulation of the zip, and it naturally closes by a well placed velcro, when closing the zip to the top.
The hood is well built with 3 compartments garnished generously, without counting the bead which made the tour of the face, making it very comfortable and well insulated hood.
Finally, the bag comes with the grade II is in our view the best of this test: light (65g), Cordura, and allowing a very efficient and compression without distortion through the flap and its 4 straps. Also note that Sea-to-Summit offers his bags of compression in various sizes, sold separately.
The Talus II is very compact when compressed (about 5L with a reasonable compression, either the smaller volume of our comparison).
Even the storage bag is well designed: it is the only bag of the test provided with a bag of practical rectangular storage with zipper and handles, as well as a large washing bag.
In conclusion, the slope is a good sleeping bag, very comfortable, well finished and durable, for those adapt well to a lining in 60/40 (who sleep on their back, or who are used to turn in the sleeping bag).
Weight measured (single sleeping bag): 1066g (size Reg / 185cm)

What we like
- Treated fluffUltra-Dry Down for better conservation of the thermal properties in wet conditions
- General build quality: careful side construction, zip in low position, insulating flap zip, collar “3D”, footbox anatomical…
- Excellent comfort of the entire hood/collar/Chin, the settings are forgotten (staggered cords) and can be adjusted all pleasantly, with very good insulation
- Exemplary finish, in particular:
- Building confidence in terms of sustainability
- Neat internal seams

What we do not like
- The lower back (differential fill 60/40) filling a little bother us by turning on the side (as much as the distribution of down in the less filled compartments tend to become less homogenous).The insulation will be more effective in lying on the back, or if you like turn you on your side without turning the sleeping bag.
- Duvet duck to power inflating bags tested slightly lower than most, but still of good quality (750 + cuin according IDFB)
- The adjustment cords and their blocker little are not so obvious to use at night
