Glow-in-the-Dark Thermometer and Compass Keychain for Everyday Adventures
A compact Montbell accessory built for everyday reliability on the trail. The Montbell Luma Gage is a dual-purpose tool that combines an easy-to-read thermometer with a dependable compass. Designed to clip effortlessly onto your backpack, zipper, or keys, it tracks temperatures in both Celsius and Fahrenheit, while the backside features a handy chart to help you estimate perceived temperature based on wind chill. With glow-in-the-dark markings on the surface and the compass’s four cardinal points, this small but mighty tool remains highly visible and functional even during pre-dawn starts or twilight descents.
Why We Love It
Small, practical, and well-made—this is the kind of item you don't think about until you need it. At X-Boundaries, we love the Luma Gage because it weighs virtually nothing (just 11 grams) but provides critical environmental information at a glance. The glow-in-the-dark feature makes it incredibly easy to locate your pack inside a dark tent, and having a reliable, battery-free analog backup for temperature and direction is a must-have safety habit for any serious outdoor enthusiast.

Bought this strap to attach to my Montbell hat, the strap is of high quality and the adjustment of the buckle is smooth and easy.
Material looks good, I have used their short sleeves before and it works very well in hot and humid weather. Now trying out their long sleeves and would expect it to be the same.

Montbell Thermal Men's Trail Action Jacket - CLIMAPLUS® Active
This is to replace what I’d lost on a recent trip. The goretex works very well, shielded me from sudden downpour. The cap is also very fitted for me, not all caps can do. Though the price here in SG is $20 more than what I got from Japan but it’s worth the buy!
