FAQs

Will The Aspen fit me?

People from 5’2” to 6’1” with a wide range of bust and torso widths have tried The Aspen and found in comfortable. People with A cup to DDD cup bra sizes like the fit!

What about load lifters?

Load lifters are designed to bring heavier loads closer to your back when wearing a framed backpack.

The Aspen naturally hugs your back as it is a frameless pack. In addition, since it is designed to carry lighter loads, load lifters aren’t necessary.

That said, if you would like to add custom load-lifters, please reach out to us at support@symbiosisgear.com.

Is The Aspen waterproof?

The Aspen is water resistant. It is made of extremely durable Dyneema® fabric, so by nature, it keeps water out. You’ll see that water beads up on the outside. If you plan on hiking for many hours in heavy rain we recommend putting your sleeping bag and warm layers in a dry bag or trash compactor bag.

Does The Aspen work for men?

Men with narrower frames have found The Aspen to be comfortable! Those with wider shoulders (6’ tall and over) do not fit The Aspen well.

What if it doesn't work for me?

You are welcome to return it for a refund within 30 days of purchase if it has no visible signs of wear or use.
