Lowepro Whistler BP450 AW II, 36L - Grey

The Lowepro Whistler BP450 AW II, 36L - Grey is a heavy-duty, four-season technical alpine transport system engineered for professional outdoor videographers, extreme sports photographers, and wilderness remote content creators. Constructed to thrive in brutal environmental extremes—including sub-zero mountain snowfields, blowing desert sand, and torrential downpours—this pack features a rigid internal structure capable of lashing down heavy mountain hardware like skis or a professional tripod without warping.

Upgraded to align with Lowepro’s eco-conscious manufacturing initiatives, the Whistler II utilizes up to 66% certified recycled fabrics while delivering specialized spatial configurations for portrait-gripped pro cameras, drones, and essential survival gear.

Product Features in Detail

66% Green Line Recycled Performance Fabrics
Built to endure punishing field abuse while minimizing its global environmental footprint, this bag is manufactured with up to 66% recycled fabrics. Monitored via the integrated Green Line progress indicator on the back panel, this advanced textile profile repurposes post-consumer waste into high-tensile yarns that maintain full puncture, tear, and moisture resistance under extreme outdoor stress.

Dual Top-Load and Hinged Body-Side Access Matrix
To streamline workflow on unstable terrain, the pack features a hybrid entry layout. A long lens attached to a camera body can be drawn instantly from the top-loading hatch. For deep organization and lens swapping, the main compartment utilizes a secure, hinged body-side rear entrance that opens fully without exposing your internal electronics to wind, snow, or mud while the bag is placed on the ground.

Rigid Alpine Frame and Multi-Point Lashing System
Unlike standard camera backpacks that sag under uneven weight distributions, the Whistler features an uncompromisingly rigid internal structural frame. This heavy-duty reinforcement lets you secure heavy, oversized alpine gear—such as full-sized skis, snowboards, ice axes, or professional video tripods—firmly to the side compression tracks without collapsing the interior camera compartment.

Expanding Front Pocket with Waterproof Drainage Barrier
Designed specifically for backcountry survival logistics, the spacious front panel compartment expands to hold essential safety gear like an avalanche shovel, snow probe, climbing ropes, or extra clothing layers. This chamber is separated from the delicate camera core by a heavy-duty waterproof barrier wall and is equipped with a functional drain hole at the bottom to safely exhaust water from melting snow or wet equipment.

CradleFit 15-Inch Laptop Sleeve with Mechanical Ejector Strap
The dedicated tech compartment features Lowepro's signature CradleFit construction, which suspends a 15-inch laptop above the base of the pack to protect it from sudden drop impacts. To streamline packing when your bag is tightly packed or when navigating airport security checkpoints, the sleeve integrates a specialized pull-tab ejector strap that smoothly lifts the computer out of the slot.

High-Visibility Orange Utility Pocket and Modular Drone Pads
The top accessory vault is lined with a high-visibility orange interior fabric, making it easy to spot loose parts, filters, or memory cards in dim alpine light or dark winter storms. The internal layout is complemented by specialized protective insert foam pads engineered to safely isolate a professional drone body and its wireless remote controller from other loose field tools.
