Mayfly Pack 22

Dec 18, 2025

Disappointing

I was disappointed that it was cheaper looking than I thought.
I bought it for sauna use, but it would be better if it were a bit more stylish...

A great travel companion

With a packable design comparable to an eco-bag, it has an excellent capacity of 22 liters when in use. The side pockets are reasonably deep, so there's no worry about things falling out. I bought this one for my wife.

For lightweight items only!

It can hold a lot, but since the fabric is thin, it seems better suited for lighter items.

Be careful of rain

It's lightweight and versatile, suitable for everyday use, traveling, and trekking. With this one bag, a minimalist can go anywhere.
There are no pockets or dividers inside, but there's a small zippered pocket on top to keep essentials like a small wallet separate.
Since it's foldable = a flat cloth, it can hurt your back if you put hard items in it. I put clothes in the back to use as cushioning.
It does not protect against rain. Everything gets wet.

In travel bags

It becomes compact, so I can use it as a second bag while traveling, as an attack backpack for trekking, or as a spare bag for shopping.
The fabric is thin, but the strength is decent.
As others mentioned, some colors may be see-through inside.

As a sub bag

It's very thin and lightweight, making it easy to use even in summer.
It can be folded compactly and carried, making it great as a sub bag.
The shoulder straps are relatively thin, so I don't think it's suitable for long hours of wear.

Lightweight and cute colors

It can be used in any situation, whether town use or outdoor activities, and it's very useful for when my luggage increases while traveling. I like the mauve color because it's easy to match.

Compact

I purchased this to carry instead of a heavy backpack to the mountain lodge, buying a compact storage backpack this time.
I chose it for its lightweight and compact qualities.

Light and just right

I bought it for sports watching. I was looking for a bag that could fit a towel, muffler, uniform, water bottle, and seat mat, while not being too big or too small, and I found just the right one. Since I usually wear dark colors, I chose lighter colors for small items. The fabric is thin and a bit see-through inside, but I was aware of that, so for those who are concerned, I think choosing black or darker colors would be better. It was a good purchase.

Perfect for attack packs

I was looking for an attack backpack for tent camping, and this Mayfly pack that had high ratings was my first purchase. The new color combination is good, and it's lightweight and compact, so I'm very satisfied. The durability is yet to be seen, but I believe it will be useful. It's a versatile backpack suitable for daily use.

Travel

The lightest weight ever!
The shoulder straps are sturdy, so even if I put a lot of items in, my shoulders don't hurt.
However, it's disappointing that the elastic for holding drinks in the side pocket is too loose.

Light and compact

I use it during my travels with a carry-on suitcase while sightseeing at the destination. It's lightweight and can be stored compactly, making it convenient. The fabric is thin, so it’s slightly see-through inside, but it doesn't bother me.

Very light

I purchased it for traveling.
The size and usability were good.
Even when I adjust the shoulder strap, it tends to loosen easily.

I bought it thinking I would use it on my trip.
It's compact, so it doesn't take up space in my luggage,
and I'm glad I got it.

For mountain climbing

I bought it for light hiking or trekking. It's lightweight and washable, so I'm satisfied. It loses its shape if heavy items are put in it, but I think that's just the nature of the material.

Packable and convenient

I bought it for tent camping. It fits into the inner pocket when rolled up. It has a simple belt at the waist, and both side pockets can hold water bottles.
The fabric is thin but stiff, making it suitable for everyday use as well. The light colors may show the inside a bit.

As a sub-bag for travel

I have been using an older model as a sub-bag for travel for several years.
This time, I purchased it for my husband.
I considered other brands, but ultimately, I chose this because of its size and comfort, which are the best.

Solar Blue

Until now, I had been using a flight-weight pack as a second bag while traveling. Compared to before, it has added chest support, a hip belt, and side belts. Also, the material at the bottom has increased strength.

Light and has a lot of space

I was using a Gram daypack as a sub-bag, but I was looking for something a bit lighter for exploring low mountains and resort areas. I heard from a few staff members at my go-to store that they use it, so I'll bring it to explore places like Kamikochi.

In terms of size, it’s neither too big nor too small, it's just the right size to handle and is lightweight and compact, making it easy to carry for quick outings or shopping, so it's very useful and versatile.

Light and durable, for mountains and towns

It's very convenient and my favorite.
At first, I used it as a sub-backpack at the final point of the mountain with just the essentials, but recently I go to low mountains only, so I have come to only use this. I also use it a lot in the city and while traveling.

Purchased for mobility during travel

When folded, it becomes small enough to be an eco-bag and there are no issues with packing. The feel of use also fits my body and feels natural.
