In part two of this investigation, we see what happens when you crush insulation beneath a stack of concrete pavers - again and again.
What is MVTR's role in active insulation garments?
In his new column, Simple Gear Tests, Backpacking Light author Rex Sanders provides suggestions for at-home gear tests you can do with minimal time and expense. First up - a plan for verifying the capacity of your USB-rechargeable devices.
Air permeability vs. moisture vapor transmission rate (MVTR): which one impacts moisture transport more in wind and rain jackets?
This study compares the performance of four jackets made with fabrics that span a wide range of air permeability rates and moisture vapor transmission rates (MVTR). The study shows that significantly greater moisture removal can be achieved as a function of jacket MVTR than jacket air permeability.
Rex Sanders reflects on what he learned after eight months of digging into backpacking standards.
The latest findings on thermal degradation in synthetic insulation from Stephen Seeber may surprise you in this By The Numbers column.
We throw some quantitative testing at an oft-repeated synthetic insulation claim to measure the thermal performance of wet insulation.
Stephen Seeber subjects ten fleece samples to rigorous thermal testing.
Stephen Seeber presents measurements of several market-leading insulations along with four performance metrics to help judge their performance.
Backpacking Light publisher Ryan Jordan subjects the Jetboil Stash to the StoveBench testing protocol to answer the pressing question: is this innovation, or lipstick on a pig?
