Choosing Bivy Sacks

A bivy sack is a low-profile, waterproof barrier for your sleeping bag that offers an ultra-lightweight alternative to traditional tents. Originally used by climbers who needed lightweight, compact shelters for multi-day ascents, they are also popular among backcountry minimalists who want to shave weight. They don't offer room to move, but they're easy to pack.

Structured Bivy Sacks
Structured bivy sacks, called bivy shelters, have small suspension systems that expand the head area to provide some room to sit up in. This makes the confined space more comfortable fit.

Bivy Openings
The most basic bivy sacks have an opening at the head to let you breathe and allow moisture to escape. More advanced models use mesh panels to keep bugs out.

Bivy Fabrics
Most bivy sacks use two different fabrics to balance protection and weight. The bottom fabric is heavier for durability. The upper fabric is usually lighter and features a waterproof/breathable laminate.

How to Buy an Alpine Touring Ski

Skin to the Summit & Shred the Stash

You’ve decided to leave the crowds at the resort and hit the skin track. An alpine touring ski balances easy handling, floatation, and weight to give you the most versatile platform for earning your turns on the way up and shredding trees, powder, and chutes all the way down. An AT ski is a powerful addition to your quiver and due to its ability to handle a variety of conditions and terrain, it might serve as both your resort and backcountry ski.

Weight:

When you’re earning your turns, every ounce counts. An AT ski is usually heavier than a rando or Nordic ski and significantly lighter than a powder or big-mountain freeride ski. Wood or composite materials help shave weight where it counts

Camber & Shape:

Like an all-mountain ski, you can expect a blend of camber underfoot and tip-and-tail rocker or early rise to add a touch of surfy maneuverability for tight terrain.

Other Features:

Tip and tail grommets for skin attachments, a snow-shedding topsheet treatment, or an ultralight core—it’s all about a balance of uphill speed and downhill performance.
