These are perfectly ordinary disposable handwarmers. Nothing wrong about them per se.

Marketing

Except with the marketing, of course. They claim that these last for 12 hours. Maybe with a precise thermometer you might detect some faint memory of heat radiating from these after 12h, but in practice these become useless at around 6 hours, that is the normal time for other brands as well.

So these warmers are no worse than others, but doubling the time claim is just cheating the customer. I recommend supporting a vendor with more realistic claims.

This is a down insulated air sleeping mat for colder times.

The pack is not too massive for a winter sleeping pad, and it comes with a good looking repair kit. (Own work. License: CC-BY-SA.)

With an R-value of 5, this sleeping pad is good well below freezing temps. Tested at around -7C, though not directly on snow. Slept well, so the essentials are in check.

The mat opened but not filled. The stuff sack doubles as a “wind sock” pump. (Own work. License: CC-BY-SA.)

My only complaints are with the stuff sack. It’s possible to roll the mat and get in that way, but in practice this is really hard with your fingers numb. I would recommend just stuffing the mat into the sack.

As is visible above, the sack also works as a pump. It’s nice that you don’t have to buy it separately, but it’s also not as good as a traditionally shaped pump sack. Gets the mat filled though.

All in all this is a decent winter sleeping mat.

This is a collapsible plastic trowel for digging… umm… holes to the ground for you know what when you’re backpacking.

The trowel in it’s extended form. (Credit: Sea To Summit. Fair use.)

Does it work?

Yes, it digs a hole and packs pretty small. This is also a pretty handy thing for shoveling snow to your pot when you’re melting drinking water in the winter.

Is it good?

I wouldn’t go so far. The collapsible structure is not very tight, aka it clatters cheaply. Same thing with the handle container lid.

The verdict

This will do but I would recommend checking out other options as well. For example, there’s an aluminum version of this as well. Maybe that would feel like a proper trowel? Or something else entirely.
