What to Compare Before Buying
- Size: The unfolded and folded dimensions are stated, so compare both against the space you need to carry and store the bag.
- Carry style: It is set out as a chest bag, crossbody bag and shoulder bag, so check which carry position you prefer.
- Strap fit: The shoulder strap adjusts from 64-108 cm, which is the main fit check for comfort and carry position.

Compatible, Sized and Folded for Carrying
The bag is sized at about 37.5 x 20 x 9 cm when unfolded and folds down to 18.3 x 11.8 x 6.6 cm. That makes the packed form much smaller than the open form, so the key check is whether the unfolded size suits the items you want to carry and whether the folded size suits your storage space.
The strap can be adjusted left or right and has a 64-108 cm adjustment range, so the carry setup can be matched to your preferred side and position.
Before You Decide
Confirm the unfolded size, folded size and strap adjustment range against your needs before choosing an offer. If the side you carry on matters, check that the left- or right-hand strap orientation matches your preference. Also make sure the bag style and pocket layout suit the items you plan to keep with you.
