Boulder 450 Test in Patagonia

The manufacturer of sleeping bags Warmth is Polish Yet. The brand sells its products in France under the brand Yeti and under that of Warmth according to the distributor (the Warmth brand is sold in computerminus.com). Not necessarily very easy to find it from the perspective of the user even if we can quickly find the info on the net.

Boulder range includes models 300 and 450. The 300 has an extremely comfortable temperature to -5 ° C, I see myself badly in the test condition bivouac in Patagonia. In the mountains, even in summer, temperatures can drop below. So the Boulder 450 that I tested in Patagonia in Nahuel Huapi National Park.

The Warmth Boulder 450 is a type of sleeping bag sarcophagus partitioned into 15 boxes to reduce thermal bridges. The weight / temperature relationship is interesting, the compressed volume is good without being extraordinary. When it slips into the sleeping bag, the cozy comfort we note at the outset. I am very surprised that this is duck down, deemed a bit less comfortable and the swelling goose down.

When hiking, I was not able to push the sleeping bag fully in these extreme since the temperature at the lowest was 5 ° C. At this temperature, I slept in a tent on a mattress Nemo Zor flat (not ideal for insulation), wore a merino baselayer, the collar was closed and the hood tight sentence. Never had the slightest feeling cold. And I’m not one to have all the time too hot. Along the zip, the protective strip is effective to prevent cold air from infiltrating. The collar is very easy to use. It adjusts by pulling a cord. It actually prevents the outside air from entering the bag as well as the heat loss from the top. The hood fits also with a cord even if there really regret that I take a long pull on the cord to tighten the closest to the face. If the hood was preformed, we would not have this small problem.

The outer fabric Q15 (37g / m²) is according to the manufacturer waterproof and windproof. I have not been able to verify on the ground. The hairdryer, it’s true that cutting wind well. After passing the sleeping bag in the shower, I would say it effectively déperle early. But do not expect to sleep outside in the rain. By cons, in the backpack, I think there is no need to worry on that side. It would also protect the down from ambient humidity. A check in wetter conditions than those encountered in Patagonia.

A small pocket which is closed by a velcro finally can store some effects: eg earplugs or an iPod Nano.
