What Insulation Level Do You Need?
Rocky Boots’s Thinsulated footwear all offer superior protection, but the level of protection varies depending on the measurement of the insulation. Insulation is measured in grams, the actual weight of the material.
200G Insulated Boots
Rocky’s lowest level of insulation is 200 grams. This insulation level works well for cool weather at lower activity levels. The lightweight nature of 200G boots helps prevent overheating if the temperature rises while still offering adequate protection.
400G Insulated Boots
400 grams of insulation are also good for cooler weather with lower levels of activity. If 200G isn’t enough to keep feet warm in the snowy conditions, 400G is the logical next step.
Rocky’s S2V line of insulated boots offer comfort and durability that’s difficult to top. Thanks to their 400G insulation, S2V boots help soldiers go the extra mile through cold and wet conditions without the distraction of sore and soggy feet.
600G Insulated Boots
600 grams of insulation is ideal for more uncompromising environments where temperatures dip into the low negatives. Boots with 600G insulation can protect against more frigid temperatures (-40°F) if the soldier remains active but aren’t the best option for long periods of standing in negative temperatures.
800 grams of insulation is where boots begin to fall into the extreme cold category. This thicker insulation helps soldiers keep warm in freezing temperatures without having to keep moving constantly. Because of its heavier nature, 800G is the heaviest level of insulation to use if the soldier will be moving non-stop.
1000G Insulated Boots
1000 grams of insulation are for those who will regularly trek through extreme cold conditions that require submersion in heavy snow or frigid water.
1200G Insulated Boots
1200 grams of insulation are perfect for dealing with extremely cold icy water. While 1200G is probably too much for the average snow day, soldiers need this level of protection when stationed in the coldest of environments. These boots are noticeably less breathable than boots with less insulation, but their heat-retaining qualities more than make up for this.
1400G Insulated Boots
1400 grams of insulation is the highest grade Rocky Boots offers and is designed for the most severe cold weather environments. 1400G boots are designed for temperatures well below 0°F and can be used in the Arctic Region, Antarctic, and other extreme weather locations.
