I think I’m ready to retire my 3-4 year old REI Flash 18 pack. This pack has been great for three-season (fall, winter, spring) hiking here in Phoenix but it’s starting to delaminate on the inside and I’m tired of carrying a pack with no bottle pockets. I’m wondering if anyone has any suggestions for a small daypack that fits these criteria:
- One or two exterior bottle pockets that fit a 1L Smartwater bottles. I don’t use hydration bladders.
- Small size (15-20 liters)
- Daisy-chain on the shoulder straps
- Some way to attach trekking poles on the exterior
- No/little structure (I don’t need/want padding/3D mesh on the back)
- Typical load: 2-3 liters of water, FAK, snacks, tiny sitpad and (rarely) a light fleece.
I’m only aware of three packs that really check these boxes:
- Zimmerbuilt Hybrid Pack (with custom bottle pockets added)
- ZPacks XSmall Zero Pack (with bottle pockets added)
- KS Ultralight Daypack (add daisy chains on shoulder straps)
Can anybody add to this list?
