Lost Park Pants

Kifaru engineered the Lost Park Parka to be incredibly durable and water-repellent while remaining extremely lightweight.  With worldwide success of the Parka we decided to release pants as well.  It’s breathable, lightweight, and durable water-resistant fabric is made for the most extreme conditions and use. Kifaru uses Climashield APEX insulation, which is treated with a DWR (durable water repellent) finish that keeps it from absorbing water if it’s exposed to moisture. In an innovative construction process, the insulation is sewn into a tough inner lining to create one consistent layer of warmth that leaves no cold spots that could otherwise be caused by insulation clumping.  Protection of your knees/shins and rear are insured with double paneled Cordura.

    I have the parka and pants in camo. I’m 5′ 11″, 180 lbs. and the large/large fits me perfect with some room for layers. I have the passthru pocket which I love for the pack belt or just the ton of room it provides for, stuff.
    I use the suit for outdoor and wildlife photography. It is a game-changer and maybe the best pieces of gear I’ve ever owned. I have plowed through significant brush with it and have not had a problem but I know better than to push the limits as they are not designed for such things.
    It is now in the single digits (F), and below zero, here in Idaho, and I’ve stood around in the suit for a long time. I have never been cold in the slightest with this suit with just a fleece shirt and nylon pants underneath.
    The plastic cinch things, on the hood, can be passed, one through the other’s loop, to keep the hood bottom pulled snug under your chin.
    The zip system on the pants is a huge plus. I hike without the pants but when I stop I can have them out of my pack and on in 60 secs. If I do hike in them, or if it gets too warm with them on, I can just vent them with the zips and usually that fixes the problem.
    You don’t need pockets on the pants and I’m glad there are none. I can use the pockets of the pants that I have underneath and just zip down the puffy zips to access them.
    The irony is that, with so much warmth and convenience, you actually don’t feel like you are wearing anything as the suit is so light and comfy and easy to use and just floats on your body.

    Material got caught in zipper and easily tore. Velcro straps chafe and scratch waist. Otherwise the pants are amazingly warm.

    They fit as described. Haven’t used them in the field yet. The quality seems much better than other brand of puffys. I especially like the durable cordura type fabric on knees and seat. As soon as funds are available I will be ordering the parka!

    Definitely an athletic fit but can easily fit a pair of attack pants with long Johns underneath. I’m a 30” waist and the medium is perfect.
