Description

This is a level 1, “silk weight”, thermal base layer that was used in the US Army. The base layer is moisture wicking, breathable and lightweight. It helps keep you warm and dry while moving around and sitting. The level 1 base layer is very durable and can be worn like compression clothing with it tight against your skin, or more loosely depending on your preference. The Gen III ECWCS design allows moisture to escape and at the same time has water-resistant properties.

Features:

  • ECWCS Level 1 – These are base layers meant to be worn in a variety of temperatures and form the base for all ECWCS layers. Material is quick drying, moisture wicking, breathable and lightweight. Layers consist of a top and bottom that are typically tight fitting to help with insulation as well as breathability.
  • Part Of ECWCS – This is part of the US Army Extended Cold Weather Clothing System that is used to protect the wearer from cold to extreme cold weather situations and environments. The system consists of 7 levels of clothing and various accessories that can be worn in multiple configurations. When worn properly in appropriate conditions the system is designed to keep Soldiers warm in temperatures from +40 degrees to -50 degrees Fahrenheit.
  • Moisture Wicking – Garment wicks away moisture which decreases drying time of the material and less soaking.
  • Breathable – Breathable means it allows moisture to escape to help keep the wear dry even when sweating.
  • Lightweight Construction – Built with lightweight materials for extended use.
  • Water Resistant – It can be exposed to water for a short period of time without being damaged or saturated with water. Generally not recommended to submerge Water Resistant items unless item is made for that level of exposure.

  1. Josh (verified owner) –

    Ordered this last week and it came within 4 days. Great quality, awesome customer service, fast shipping.

  2. g49o2 (verified owner) –

    Fast and friendly service from Venture Surplus again. Great product, nearly perfect. The sleeves would need to be about an inch-and-a-half longer before I would be able to get my thumbs comfortably into the thumb holes. But as a tall, skinny guy I am used to things being just a little short. I don’t think I would use the thumb holes very much anyway.

  3. Gil LeBlanc (verified owner) –

    MADE IN USA PROUD, excellent base layer, ordered 2XLXL, loose fit I’m 5’11” and 250lbs, very comfortable with sleeves and thumb hole perfect length, ordered the drawers in XLXL, will review when rec’d, thank you Venture Surplus with your excellent service and fast shipping, son of a KOREAN WAR ARMY VET-I’m very proud to be a humble civilian.
