khemwrote a review of Gregory Amasa 6L Backpack - Women's on April 7, 2018
Familiarity: I've put it through the wringer
The Amasa pack is a very well engineered mountain biking pack with great fit and functionality. I have had several mountain bike packs that I've put through the ringer, and this pack from Gregory is holding up very well.
The ventilated back and straps don't add unnecessary weight and heat while riding in warm summer temps. The 3L hydration bladder is MORE than enough for long rides, and is easy to fill and clean. One small issue I have had is with the bite valve coming apart, but I attribute that more to me bitting to heard while struggling on the uphill climbs than faulty design.
I like the multiple pockets with easy access for glasses, phones, tools, ect. The included tool bag also helps keep your stuff organized and easy to find. Here is where my biggest gripe with the Amasa 6 comes in. Unlike the larger versions of this model, the 6L does not come with hip-strap pockets. I have had previous small hydrations packs from Gregory and they had hip-strap pockets, so when I got the Amasa I was mildly disappointed that this was not a feature. Pocket disappointment aside, I would still highly recommend the Amasa 6. It is a fantastic size for cross-country mountain biking with a great, secure fit, plenty of room for layers and liquids, and a clean looking design.
