I’ve been a hiker for 8+ years and have learned the hard way that wearing the wrong day pack can ruin a hike! When hiking, you’ll be wearing your backpack for hours, so you’ll want it to be comfortable and a good fit for your body.
The best women’s hiking daypacks are designed with a woman’s anatomy in mind. For Gregory, this means a hip belt angled to fit the shape of a woman’s hipbones and shoulder straps that are shaped to work with a woman’s bust. Gregory also carries the first line of plus-size backpacks, that fit 2x-6x in apparel sizing!
To help you figure out which Gregory day pack to buy, I’ll share my experience with 5 different Gregory day packs and compare their features.

How To Choose A Hiking Day Pack
If you’ve ever visited an outdoor store like REI, you’ve seen how many different day pack options there are to choose from! It can be a bit overwhelming, so here are six things to keep in mind when choosing your day pack:
- Capacity: Make sure the pack is large enough to hold all of your gear, but not too big that it becomes cumbersome. Most day packs have a capacity of 20-35 liters, while larger packs for overnight trips can range from 50-80 liters.
- Fit: If you can try your day pack on in-store, look for a pack that fits your body well, with shoulder straps and a hip belt that are properly adjusted to your size. It’s a good idea to try on the pack with weight in it to ensure a comfortable fit.
- Comfort: Padded shoulder straps and a hip belt can help distribute the pack’s weight evenly across your body, reducing strain on your shoulders and back. I recommend looking for a pack with well-ventilated padding to help reduce sweat buildup.
- Durability: Choose a pack made of high-quality materials that can withstand the rigors of the trail. Bonus points for buying from a brand like Gregory that has a lifetime warranty on their packs!
- Weather resistance: If you are hiking in wet conditions, look for a pack that comes with a rain cover or is made of waterproof materials.
- Extra features: Consider additional features such as external pockets, hydration compatibility, and a removable waist belt.
