High Peak’s Alpinizmo Latitude 20
- Very warm
- A bit constrictive
Winner of both our Best in Class and Best Value awards in this class for 2013, the Latitude boasted the best warmth-to-weight ratio in this class, and comes in at a remarkably low price. High Peak's proprietary “Cozy Loft Micro-X” fill utilizes hollow-core fibers woven with solid fibers to create an compact insulation with a great R-value.
The Latitude’s polyester fill doesn’t puff up like down or other synthetic lofts, but the dual density insulation (feature a blend of hollow-core fibers for added insulation and solid fibers for greater durability) proved wonderfully effective at holding in heat. I stayed comfortable as snow fell during a 30-degree night in the Olympic Mountains, though some of the leaner testers said they got a bit chilly once the thermometers dipped below freezing.
The Latitude stuffs neatly into is standard 7x15 compression sack, which can then be cinched down to about 7x10 inches, making it the most compressible bag in this class. When unpacked, it doesn’t immediately puff-up into lofty splendor, but they again, the Latitude’s Cozy Loft Micro-X fill is relatively flat to start with. We found no real change in amount of loft even after multiday trips and soggy nights of use.
Warmth to weight ratio
Despite the relatively flat appearance, the bag did keep us warm. Indeed, it wasn’t too far off the lead in terms of warmest of the class. So taken together, the Latitude was the clear winner in this category.
The biggest knock on the bag came in terms of sleeping comfort. I found the Latitude a bit snug around my shoulders, and felt a definite lack of wiggle room in the footbox. My more slender colleagues weren’t as constricted, but they too said they felt the bag was a bit too tight for comfortably rolling into other positions during the night.
Loft retention proved to be slam-dunk for the Latitude. Of course, we expected nothing less from a bag that starts with a low-loft insulation. But after using the bag in a variety of conditions, including tucked under a desert juniper in the Juniper Dunes Wilderness Area of Washington, the Latitude showed no signs of stress, strain or tears.
EN comfort limit = 30ºF / -1ºC

How We Tested It
All bags were tested on Therm-A-Rest NeoAir XLite for consistency throughout the test. Bags were used in the Olympic National Park rainforests, deserts of southern Utah, and the Cascades of Washington and Oregon for a minimal of 8 nights with at least two different testers. We also machine-washed each bag twice in front-loading machines using any specific manufacturer instructions/recommendations when available.
The products featured in this test have been loaned to the Gear Institute. For more on our policies regarding editorial objectivity and sample returns, see here.
