What is Reddit's opinion of Hotsnapz Reusable Hand Warmers & Body Warmers - Instant Heat Packs?

From 3.5 billion Reddit comments

For emotional comfort I am partial to Ben & Jerry's Vanilla Caramel Fudge Swirl Ice Cream myself...

On a more physical front heat packs can be amazing for pain/cramping and I can't recommend these enough https://www.amazon.com/HotSnapZ-Reusable-Hand-Warmers-Body/dp/B004CV1OZI/

As other have said let me know where and I am happy to send some to a amazon locker near you.

I usually carry one a re-usable heat packlike these in my shorts pocket so you can pop one and stuff it down your wetsuit if you or a buddy get cold mid dive.

Using the large chest size one and a 7mil I was comfortable doing an hour long dive in some FREAKING COLD!!! water (41f/5c)

I have the same issue as you but live in Maryland so we aren't (normally) as extreme. The problem is made worse when you have small bins that don't have a lot of thermal mass like mine (at least mine are insulated). I'm looking at some of the sealed reusable chemical warmers that at filled with sodium acetate. The ones that you click a metal disk internal that set's off the reaction. like this --> HotSnapZ

My concern is that my bins are so small that I they may get too hot except for the depth of winter. They get to about 130F and last for an hour. I need to do some experiments to see how a primarily coir-based bedding will conduct and then hold the heat. Ideally, I need a big walk in freezer to test before winter but that may be hard.

I think something like these combined would give you the most flexibility.

Keep in mind you have some HUGE veins in yours legs and if your calves are losing temp your core is losing temp.

Additionally these can be used to help deal with the cold

This is me in a 5mm wetsuit right before I jumped in the water to do this dive.

I use the large size of the heater packs he described above (plus hood and gloves) and I was comfy right to the end of my dive.

I usually carry the smaller packs in a pocket on dives below 65 for when my dive buddies get cold I can activate it and hand it off and the stuff it down the front of their wetsuit.
