In this Unlimited video podcast, Rex Sanders and Ryan Jordan discuss sleeping bag temperature ratings, the ISO 23537 temperature rating standard, and how consumers can interpret the standard to make better buying decisions.
Science & Technology
Dive into the "how things work" side of lightweight backpacking gear and techniques. Our S&T articles include summaries of testing reports, research projects, and more. Discover the validity of manufacturer claims, the scientific basis of design, or how and why equipment performs differently in response to various environmental conditions.
In this installment of Standards Watch, Rex Sanders tackles sleeping bag ratings: the standard, the pros, and the cons.
In this article, I present a DIY testing device (and test results for 30 fabrics) that allows me to measure the hydrostatic head of “waterproof’ fabrics at home.
This article attempts to determine how a heat exchanger welded to the bottom of a pot actually affects fuel consumption.
The goal of this test is to determine the effective age of your backpacking water filter based on comparing its current flowrate to its flowrate when new.
StoveBench defines a protocol that is used to measure two important backpacking stove performance features (power and efficiency) in order to determine a single, quantifiable performance factor called the StoveBench Score.
This technical series addendum addresses the role of propane and cold temperatures in canister stove performance.
Instead of buying a new fuel can for each trip, discover techniques for transferring gas between stove canisters.
This article tests various canister warming techniques for preserving the efficiency of canister stoves in sub-freezing temperatures.
Evaporative heat loss in upright canister stoves extends boiling times and changes fuel mixture composition. Here’s how to combat it.
