FEATURES
- Crafted from either Black Ultra 200 fabric or the weight-saving Gray Ultra 100 fabric, the Ultra material showcases a woven Ultra High Molecular Weight Polyethylene (UHMWPE) front layer fused with a waterproof backing. Renowned for its exceptional abrasion and tear resistance, Ultra fabric stands as Zpacks' strongest fabric offering.
- The Sub-Nero features an interchangeable strap design allowing you to pick the perfect strap for you. The design also allows you to swap out straps for specific adventures. You can choose from our comfy Standard S Straps, Small/Women's Straps, or our Vest Style Straps with integrated water bottle pockets. Check out the Sizing, Straps, & Fit tab for more information on each style strap.
- The pack material is waterproof. All seams and attachment points are taped and the pack is constructed using hydrophobic thread, making the packs highly water resistant.
- The pack should keep water out in typical backpacking conditions where the pack is not submerged or exposed to prolonged periods of heavy rain. We still suggest using dry bags or a pack liner to protect important items like your clothing and sleeping bags.
- Provides enough space for gear and food to accommodate most multi-day ultralight adventures.
- An optional, removable, webbing belt is 2.5 cm (1") wide and has a maximum adjustment of about 127 cm (50") circumference. The belt contributes 34 grams (1.2 ounces) to the total weight. It can be trimmed down or removed.
- Features a roll top closure with a stiffened opening which allows you to compress the top of your pack as your gear load shrinks.
- Use the provided top strap to lash items to the top of your pack or upgrade to the optional Nero V-Top Strap to allow you to carry a Bear Canister or other heavier items.
- Large stretchy mesh center pocket is great for quick access items. Mesh also lets you dry wet clothing and gives you a clear view of your gear.
- Side compression straps are made from non-stretchy Dyneema® cord for squishing down the pack volume. They also allow you to stand tall items like trekking poles or an umbrella in the side pockets.
- Side pockets are sized to fit 1 or 1.5 liter bottles. They are positioned low on the pack and slanted forward for easy access without removing the pack. The pockets have drainage holes at the bottom, and elastic that keeps them tight at the top.
- Along the sides and front, you will find a variety of loops for attaching optional add-ons like our top side pockets, shock cord lashing, and ice axe loops.
- A closed cell foam sit pad measuring 28 cm x 39.4 cm (11" x 15.5") is included and adds an additional 28,3 grams to the total weight of the pack. The foam provides some cushion and support against your back. The sit pad is held in place with shock cord and comes off quickly for breaks. The shock cord (8.5 g / .3 oz) and sit pad are removable and replaceable.
