Zpacks Nero Classic 40 vs Zpacks Women's Nero Classic 40
Quick take: The Zpacks Women's Nero Classic 40 is lighter (0.63 vs 0.68 lbs).
Which one to buy
The Zpacks Women's Nero Classic 40 is the standard Nero Classic 40 with a women's strap set, added in March 2026, and in 40 L both cost $259. The standard Nero comes in 30, 40 and 50 L, the women's in 30 and 40 L, and both are meant for about 20 lb.
That 20 lb limit is real: its 2.5 in shoulder straps spread weight well for a frameless pack, but nothing moves load to the hips, so past 20 lb it's all shoulders. It's a pack that assumes a sub-10 lb base weight, which applies equally to the women's version. If standard straps ride too wide or long on you, the women's set is the reason to choose it, at the same price and slightly lighter at 10.1 oz against 10.9.
Check two details before ordering. Neither comes with hipbelt pockets, and the women's prices include no hipbelt at all (a padded belt adds $60). Zpacks also gives no torso range for the women's version, so check its chart against your measurement. Zpacks calls the taped Ultra 100X highly water resistant but still recommends dry bags or a liner, and the fabric is the thinnest of the Ultra family and wears at fold lines. Careful owners get full thru-hikes out of it; rough ones don't, and the sturdier Nero Pro exists for them.

Zpacks Nero Classic 40 vs Zpacks Women's Nero Classic 40: common questions
Does the Women's Nero Classic 40 carry more than the standard Nero Classic?▾
No. Both are meant for about 20 lb. There's no load transfer to the hips, so past 20 lb everything sits on your shoulders, and the women's straps change fit rather than capacity.
Is the Nero Classic tough enough for a thru-hike?▾
With care. Its Ultra 100X is the thinnest of the Ultra family and wears at fold lines and abrasion points. Careful owners finish thru-hikes in it, and those who are rough on gear are pointed to the Nero Pro.
