How to Measure

Use a soft, flexible measuring tape. Measure directly on your skin or over light clothing. If you don't have a flexible measuring tape, you can use a piece of string by wrapping it around the area you're measuring, marking the spot where it meets, and then lay it flat on a ruler to measure. Alternatively, you can measure a well-fitting piece of clothing with a regular tape measure and compare the measurements to your body.

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 Bust
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.

Materials

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

Shell and Lining made from Pertex® fabrics with NetPlus® Recycled Nylon

Made from discarded fishing nets gathered off the coast of South America, NetPlus® creates wind and water resistance with a soft feel - all while helping to reduce ocean plastic pollution.

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 hoodie, jacket, and vest for outdoor adventures and travel.

This jacket performs best in the temperature range of:

Temperature range bar showing recommended performance from -1 C to 18 C

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.

    This Paka vest is the only one I will wear!

    I have never been able to wear a vest as my outerwear. It either doesn't keep me warm or its so heavy I can’t wear it comfortably. But this PAKA Mayu is neither. It is so light that I barely know I have it on but I’m warm at the same time. Thanks PAKA for this great vest. The fit is great too!

    Great light weight vest. It’s not been super cold where I live yet, but I have worn it a few times. It’a great for staying warm and it lays nicely under a baby carrier. The insulation seems to live up to the description!

    Buy one

    I now own all 3 colors and use one of them daily. I am a senior citizen and have had more cold days than warm ones. This is lightweight and easy to put over a sweater or under one. I had debated whether I needed the blue one as I had it in black and tan, but after it arrived, I used it 4 out of 6 days. We are in mid October and winter hasn't started yet. Our temps are generally 40-65 at this time of the year. Even now, these are very useful and I am quite happy with this product.
