Heavy, generously cut kit with the closures described and the membranes unmeasured
Neither of these is a lightweight item and neither pretends to be. The sleeping bag cover is a stated 1,300 g or so. The dry bag is a stated 1,180 g or so. On shelves where the competition is counted in tens of grams, that is a different category of object — built for hard use and a long life rather than for a pack budget, which is a legitimate brief as long as you know that is what you are buying.
The bivy cover is a three-layer laminate with a stated 5,000 mm water column, a 225 by 85 cm cut, a 40 by 8 cm packed size and an integrated hood adjusted by elastic and hook-and-loop. Its closure gets a full description: a two-way side zip with an overlying storm flap on press studs. That loose cut is the right idea, because a cover that squeezes the bag inside it compresses the insulation it is supposed to be protecting.
The membrane is called breathable and no figure is published for it, and no test is named either. On a sealed laminate wrapped round a sleeping bag, breathability is precisely what decides how damp the inside is by morning, and it is the claim this site flags rather than repeats. No denier and no seam treatment are published either, so the two properties that determine how long the cover survives are both absent from the page.
It should be said plainly: the Mil-Tec dry bag is a rucksack. It has padded shoulder straps, a chest strap, a ventilated back panel and MOLLE webbing, and this site does not cover what is worn on the back. It is here as a comparison point, not as a recommendation. What it does publish is useful anyway — 250D PVC and polyester, roughly 35 litres, dimensions of about 57 by 29 by 20 cm and a weight to go with them, and a claim of brief submersion rather than heavy rain. What it does not publish is a seam treatment or a water rating to stand behind that claim.
Sleeping-bag cover · 3-layer laminate · 5,000 mm water column · breathable membrane, no figure · 225 × 85 cm · 1,300 g and 40 × 8 cm packed, stated
A generously cut laminate cover that publishes its water column, its packed size and its weight — and calls its membrane breathable without ever putting a number on it.
Best for: A cover bought for cut and closure rather than for weight, over a bulky synthetic sleeping bag.
≈ $84 / £57 / 53 €
This is a waterproof rucksack rather than a stuff sack — padded shoulder straps, a chest strap, a ventilated back and MOLLE webbing — and rucksacks are outside what this site covers.
Best for: Reading as a comparison point, since the carrying system puts it outside this site’s scope.
