How to Measure
1
Arm length
With elbows slightly bent, measure from the center back of neck (at the base), across the top of the shoulders, down the arm, to the wrist. Keep your arm relaxed and slightly bent while measuring.
2
Chest
Measure around the fullest part of your chest, keeping the tape parallel to the ground and comfortably under your arms. Make sure the tape is snug, but not tight. Relax your arms by your sides while measuring.
3
Waist
Measure around the narrowest part of your waist, usually just above your belly button (This will be the crease created from bending). Stand naturally and keep the tape a bit loose. Don’t suck in your stomach.
4
Hips
Measure around the fullest part of hip/seat circumference below your natural waistline. Stand with your feet together and make sure the tape is parallel to the floor and comfortably snug.
5
Inseam (pants)
Measure along the inside leg from crotch to ankle. Stand straight with your feet slightly apart.

PAKAFILL® Insulation
High warmth-to-weight ratio with a 1.6 thermal CLO value (tested by Intertek). Half the volume of down. Keeps you warm when wet (unlike down, which can be life-threatening on the mountain). Thermoregulates from cold temperatures at rest to high aerobic activity to keep you in a neutral comfort range
100% Recycled Nylon Shell and Lining
Water-and wind-resistant without any intentionally added PFAS. Shell fabric has eco durable water repellant finish and a soft feel, unlike the stiff plastic touch of most DWR jackets
Bluesign® Certified Material
Guarantees the highest level of security for consumers to ensure healthy and safe textile materials
Traceable Alpaca™ from Peru
The natural alpaca fiber used in PAKAFILL® is fully traceable, all the way back to the small farm in the Andes where it was sourced
Our Mayu Ultralight was designed to enhance the benefits of our patented PAKAFILL® insulation, performing from cold morning flights to high-aerobic activities. We achieved this comfort range with an ultra-breathable lining to perspire into the insulation and control moisture. The result is a shiver- and sweat-proof puffer jacket and vest for outdoor adventures and travel.
This jacket performs best in the temperature range of:
PAKAFILL®
Other Jackets
Sustainable Insulation
Insulated with fiber from free-roaming alpacas in Peru.
Insulated with fossil fuels extracted from the earth (synthetics) or feathers from dead birds (down).
Storm-proof
PAKAFILL® doesn’t wilt when you’re caught in the rain, snow, or wind, keeping you safe in even the most extreme climates.
Weaker when wet. Other insulations (such as down) lose their loft when the weather gets tough, putting you in a dangerous place on the mountain
Sweat and odor-proof
PAKAFILL® is naturally anti-bacterial and odor-resistant (with only 8% moisture retention rate), requiring less washing or care.
Sweaty and smelly. Synthetics trap sweat and bacteria together - a combination which results in odor.
Made with care
The fiber in PAKAFILL® is fully traceable, all the way back to the coordinates of the small farm in the Andes where it was shorn.
Lack of transparency with sourcing and where the fibers or manufacturing is from.

PAKAFILL® has ½ the volume of down due to its uniquely structured hollow air pockets, which increase the fiber’s thermal retention while allowing for increased ventilation - keeping the material light, warm, and dry.
Thermoregulating
Naturally adapts to the temperature, keeping you warm in the cold and cool in the heat
Durable
Alpaca fiber has a tensile strength of 50 N/ktex
Lightweight
Alpaca fiber has hollow air pockets that give it an incredible warmth-to-weight ratio
Water resistant
Dries faster and insulates better than down when wet
