Sizing & Product care

Yes, Gregory reservoirs are both BPA and PVC free.

Our raincovers are available in 3 sizes. The list below shows the corresponding pack liter size to match with the correct size. If you're on the edge of a size, we recommend going with the larger size to ensure a proper fit.

Small - <30L

Medium - 30-50L

Large - 50-80L

Most airlines follow dimensions of approximately 55 x 40 x 23 cm. Packs with dimensions that fall at or below those dimensions should work for most airlines. It's always a good idea to review the specific airline for exact dimensions.

Sizing yourself for a pack is easy, but it takes a little explanation. Take a spin through our Fit & Sizing page for the full details.

Ideally, we recommend carrying your pack on the plane to avoid damage in transit; however, carry-on baggage must fit easily in the Carry-on Baggage Check (different for every airline but approximately 55 x 40 x 23 cm), which is usually located near the check-in counters. Typically, packs over 40 liters are too big to carry on, although this also depends on how full you pack the bag. If you are checking a large backpack (Such as a Baltoro/Deva), you can put the backpack in a duffel for protection, use a bag-wrapping service in the terminal, or sometimes airlines offer plastic bags for free or for a small fee. If you have nowhere to leave a duffel but you want to bag your pack, we suggest putting it in a heavy-duty clear plastic ‘contractor’ bag and then using duct tape around the bag to minimize free space and loose ends. But don’t throw it away—you can carry it with you or stash it somewhere at your destination without too much concern, then use it again for the flight home.

We provide a maximum recommended carry weight on each individual product page. The max carry amount is based on the pack’s backpanel, harness, and support structure. Some packs are designed with the ability to carry more weight than others, even if the pack liter sizes are different. Check out the Specs Tab on each product page for more info, and feel free to contact us if you have any additional questions.
