Cold hands ruin good decisions. They slow your draw, break your focus, and make simple tasks feel impossible.
The Frostline Insulated Hand Warmer was born from a specific challenge brought to us by an ex–Navy SEAL who wanted more than just a place to warm his hands. He needed a secure, quiet, weatherproof storage system that could go with him on a stalk, hold mission-critical essentials, and allow fast, silent access.
That vision aligned perfectly with our own frustrations—especially the fact that we don’t like wearing bulky gloves when bowhunting. Add in years of dealing with cold hands, noisy pockets, and gear that wasn’t built for mobile hunters, and the idea evolved into something unique.
After years of discussing how to build it right, the solution finally came to life.
Every detail of the Frostline Hand Warmer is crafted with intention:
Angled Entry With Cinch Cords
Slide your hands in and out effortlessly—even with thick gloves or wet hands. Cinch tight to trap heat and shut out wind.
Highly Water-Resistant & Windproof Exterior
Built to handle sleet, snow, and freezing winds without absorbing moisture.
Large Top-Entry Pocket With Waterproof #8 Zipper
A secure dump-pocket for small gear, a water bottle, wind checker, thin gloves, or even a compact rain jacket.
Front Magnetic-Closure Pocket
Silent and fast-access—perfect for a grunt call, cell phone, snacks, a small light, or an emergency item you want instantly accessible.
Clip-In or Wear-It Versatility
Directly clips to your saddle bridge with included carabiners for the ultimate mobile-hunting setup
Wear with a belt for ground hunting, spot-and-stalk missions, or still-hunting
The goal was clear:
Create a hand warmer that also functions as a minimalist mission pack.
Whether you're:
stalking into bow range,
pushing a long hike without a full pack, or
posting up through late-season cold,
…the Frostline Hand Warmer provides warmth, stealth, and just enough storage for everything you actually need, weighing in at only 20 ounces!
Each material was chosen for durability, weather protection, and comfort:
Polyester Brush with PVC Backing – Tough, water-resistant, and wind-blocking.
Velvet Interior Pockets (High-Vis Orange) – Easy visibility in low light for fast gear retrieval.
Polar Fleece Interior (Black) – Incredibly soft and warm—the kind of fleece your hands instantly relax into.
Neoprene Panels (Windproof) – Add insulation, structure, and water resistance without bulk.
Hypalon Reinforcements – Strategic abrasion resistance for long-term durability.
Breathable Mesh Accents – Reduce internal condensation.
#8 Waterproof Zipper – Protects gear from snow and rain.
Durable Carabiners – For secure saddle bridge integration.
Keep hands warm without bulky gloves
Access gear silently and instantly
Stay light and mission-ready during a stalk
Block wind and shed water in late-season conditions
Carry the essentials—no more, no less
This isn’t just a hand muff.
It’s a purpose-built tool for hunters who value mobility, stealth, and efficiency.
It is great and as advertised, however the cuffs are so tight unless I am wearing short sleeves I have trouble getting my hands in past the wrist. Also the front pockets are sewn on with some the orange visible from the outside. contact me at [****] if you want pictures. Otherwise I like it.
I am super impressed with this product after spending the late 2025 season trying to find the best way to keep my hands warm in fingerless gloves in a saddle set up with other muffs. I wanted to give a fairly in-depth review with some gear identification to give an idea of the dimensions and what can be put in this muff/storage combo. It is well constructed, zippers work well, etc. The warmer itself is neoprene and the attached magnetic enclosure/pockets is almost like a very soft corduroy. The magnets work well and are quiet. The warmer hand openings are generous.
I walked the dog last night in a pair of Sitka liner gloves (I wear a size large) and had no issues getting my hands in and out of the warmer, with the cinch completely open or slightly cinched. Additionally, with a 6' slip lead, electronic hand warmers, a bag of treats, an e-collar remote, and a roll of poop bags, there was a slight sway of the hand warmer back-and-forth while walking with my hands outside the warmer at about a 15-minute per mile pace, but it wasn't bad and didn't make any noise. I'm sure with some additional tinkering on where you have the warmer on your body while walking in, the sway could be eliminated entirely but I had it slung pretty low to see whether there was side-to-side sway.
While I haven't tested in a saddle, I plan on using this as a replacement for a bino harness or bino hanging system in the tree while saddle hunting. The bigger binos in the photos, a pair of Vortex 8x42 Viper HDs, fit in the larger of the two pockets under the magnetic flap at the front of the warmer. Those were a bit of a tight fit when turning them sideways to close the zipper but it wasn't too difficult to close. You do lose a little volume in the smaller front pocket but I could still fit a wind checker and a Black Diamond head lamp (storm 500-r maybe?), and they fit quite easily in the bigger dump pouch.
The remainder of the photos show what I intend to run to give an idea of size. I am able to comfortably fit a pair of Vortex 6.5x32 Bantam HDs (the Vortex child binoculars, great for saddle hunting in heavy cover on public land) and a Vortex Viper HD 3000 rangefinder in the bigger of the two front pockets and am able to close it comfortably. There is no loss of volume for the smaller pocket in the front containing the wind checker and headlamp in the front pocket.
The pictures with me wearing the warmer are configured so that my rangefinder and grunt tube are in the big dump pouch, the binoculars are in the bigger of the two magnetic closure pockets, and my headlamp and wind checker in smaller pocket under the magnetic flap. With everything closed walking into the tree, it's not too large and doesn't stick out too far from your body. You can flip the magnetic flap over into the zippered dump pouch, which is fairly voluminous, and sort of presents you with 3 "levels" of access in the tree. With this set up, the hand warmer isn't heavy and there is plenty of additional room so that I could add electronic or old school hand warmers, a merino neck buff/face cover, and a pair of gloves/extra gloves.
Having the option to run it with a waist belt or the carabiners to clip into your bridge loops really provides some great options for a saddle hunter while also having secondary uses such as using it with a waist belt while ground hunting or hunting out of a tree stand (or walking the dog when it's cold!). It's definitely something that will be very useful for late-season saddle hunting, and I would highly recommend making the purchase.
It’s a 4.5/5 for me, very close to 5/5. First use was on a marsh scouting and supply run in appx 28° weather. Ripping 30mph on glass to our spot left tears which froze on my lashes. Tested without gloves or liners and my hands were more than comfortable in that wind. Pockets are solid for basics like keys, license, some shells, and phone. I have three verrrry small nitpicks which make up the half-star. 1- Love the green, but would like a few more color options. 2- the openings for your hands are good, not perfect for those with big hands. Given there’s an awesome cinch to narrow the size a little extra here would have been nice. If I try to use this with even thinner gloves, I’m not getting in one-handed. 3- durability concerns (tbd), I can see the soft fuzzy material getting roughed up when climbing trees for saddle, or poking through marsh to get to a good vantage point. Keep up the good work TN!
Fantastic handwarmers on steroids! Besides being warm, they have excellent storage for essential items as well as a couple different methods of attachment. Very well thought out.
