Warmth When You Need It. Breathability When You Don't. Designed for Mobile Hunters by Mobile Hunters.
Late-season hunting brings a unique problem: long walks to the stand make insulated boots sweat-soaked, and once you stop moving, that moisture turns to freezing misery.
For years, Timber Ninja's Beau Martonik and founder Jason Redd battled this same issue. They tried every boot cover on the market, and every one came with the same frustrations — too bulky to pack, not built with modern materials to actually block wind or shed water, and frankly, a pain in the ass to put on when you're trying to settle into a stand quietly.
After countless hunts and years of kicking around ideas on how to build something better, their shared vision finally came to life. The result is the Frostline Insulated Boot Cover — a lightweight, packable warmth system designed specifically for hunters who hike deep, move often, and refuse to be held back by outdated gear.
Purpose-Built Materials That Work Together
Every component of the Frostline system was chosen to keep you warm during long sits without adding bulk:
Neoprene Shell – Highly water-resistant, windproof, and low-bulk so it packs tight and deploys fast.
PVC Leather + Hypalon Reinforcements – Enhance durability, structure, and weather resistance while staying quiet and flexible.
Fleece-Lined Interior – Soft, silent, and warm for all-day comfort in freezing temps.
Toe Handwarmer Pocket – Slip in a heat pack for instant warmth at the coldest point of your boot.
Cold-Blocking Bottom for Elevated Hunting
The closed-cell PE foam in the bottom is the heart of the Frostline warmth system. It creates a barrier that blocks the cold transfer from aluminum or steel platforms — a must for saddle hunters and treestand hunters who spend hours on metal surfaces that drain heat rapidly.
Traction Where It Counts(2026 Update)
The bottom is also built with:
Non-Slip Traction Pattern – Purpose-built grip for wet, icy, or frosty surfaces, and designed so you can climb up and down your tree with the covers on
A tough, abrasion-ready exterior designed to hold up to extended use on saddle platforms and stand edges
This combination gives you confidence and stability without compromising stealth.
Designed for the Way Mobile Hunters Hunt
Top-Entry Opening – Easy on/off once you reach your tree
Drawcord + Sewn-In Bottom Strap(2026 Update) – Top drawcord cinches the opening, and the bottom strap is now permanently sewn in so it's always right where you need it — no fumbling in the dark.
Lightweight & Packable – Roll them tight and stash them without sacrificing pack space, weighing in at only 21 ounces!
Have yet to try them in cold weather but they are simple to put over my size 13 Zamberlans which the other cheaper options would not. Material and over all construction looks really nice!

Was surprised at how heavy duty these things are made. Wanted to try and hunt in my early season boots all season long, as I don't like climbing/sitting in my insulated lacrosse boots. Looking forward to trying these out. They sure do look like they'll do the job

I received my frontline boot covers last week. The quality of the material seems exceptional. I’m excited to have this piece of gear for the upcoming season!

The Frostline boot covers are compact and well designed. They’re easy to put on and take off, are quiet, and provide good grip for saddle platforms and tree stands. Neoprene outers provide warmth without bulk, are windproof, and highly water resistant. I finally found the perfect cold weather boot covers for all day sits in the stand.
