Rain is rarely the problem; your own moisture usually is · review
A 3-layer Gore-Tex cover that names every layer of its construction and publishes neither a waterproof figure, a breathability figure, a weight nor a packed size.
The bottom line Three layers named one by one, a length and a shoulder width — and not a single number for waterproofing, breathability, weight or bulk.
An olive green sleeping-bag cover in 3-layer Gore-Tex, stated at 243 cm long with a 98 cm shoulder width, with a 100% polyamide face fabric, a PTFE membrane and a 100% polyamide lining, and a central zip.
The construction, layer by layer. Most covers in this hub say laminate and stop; this one names the face, the membrane and the lining as separate materials. The cut is published too — length and shoulder width — which is what you measure your own bag against.
No hydrostatic head. The membrane is named and never quantified.
No breathability figure. The cover is described as air permeable, and the maker states that condensation is markedly reduced compared with simple bivy bags. That is a comparison, not a measurement, and there is no scale attached to it.
No weight, no packed size. The title says ultra light. There is no figure anywhere on the page.
The central zip is the ventilation control the maker names. On a cover with no published breathability figure, how far that zip opens is the part of the specification you can actually reason about.

Catalogued on the British and Italian Amazon stores with nobody selling it: the reference is there, the offer is not.
Nothing came back from the American Amazon store, so the buy link there opens a local search instead of a page that is not there.

It identifies the membrane, which is more than an unnamed laminate offers. It is not a number, and this hub carries a breathability column precisely because a name and a figure are different claims. The listing also states that condensation is reduced compared with simple bivy bags — a comparison, again without a figure.
The maker publishes 243 cm of length and 98 cm across the shoulders, which is the longest cut in this hub. Whether it clears your own bag is a measurement you can make, because for once both numbers are on the page.
