Frostline Insulated Boot Covers

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packable warmth system designed specifically for hunters who hike deep, move often, and refuse to be held back by outdated gear.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.
