Decathlon has been behind some of the best bang-for-your-buck outdoor gear in recent years. Its line of hyper-considered and extensively tested trekking tents all offer exceptional value for money, and I’ve been nothing but impressed by everything I’ve tried. But does that apply to ? Earlier this year, to find out about how they design, test and validate products.

And came away with a shiny new MT900 5°C sleeping bag from their trekking brand Forclaz to test. , the Forclaz MT900 5°C sleeping bag is a down-filled, 3-season sleeping bag that sits at the intersection between big-brand-feel and price. Unlike its line of backpacking tents, however – such as the Forclaz MT900 Trekking Tarp Tent which comes in at less than half the price of most big-brand competitors – Decathlon’s 3-season sleeping bag is only a little cheaper than big-brand alternatives.

So, how does it perform in comparison? I’ve had my hands on a Forclaz MT900 5°C sleeping bag for all three seasons now. That means I’ve been able to put it up against the full gambit of conditions it was built for, ranging from temperatures hovering around its 5°C / 41°F limit all the way up to balmy summer nights where the mercury remained well above 16°C / 61°F. I’ve used it in dry conditions, windy conditions and outright monsoon-style conditions during a snap summer storm in Dartmoor National Park in England.

So it’s safe to say that I’ve given it a fair crack of the whip. The first thing I appreciate.
