Sun Mountain Eclipse E-1.5 Stand Bag review

The Sun Mountain Eclipse E-1.5 is the carry-focused member of the E-Series group reviewed here. Its useful distinction is not a promised comfort result, but a compact published specification: four top sections, seven pockets and a listed 3.4 lb empty weight. The exact product page also describes Cordura nylon ripstop, a dual-strap system and a matching rain hood. Those claims make it a reasonable comparison for someone who wants a light, organized stand bag; they do not tell us how a loaded bag will sit on a particular body.

A deliberately simpler carry specification

Sun Mountain calls the bag a carry model and lists an X-FIT Dual Strap System. The 7.5-by-10-inch top is divided into four sections, with a compact footprint compared with the 7.75-inch four-way top on the E-2.5. Seven pockets include a full-length apparel pocket, a water-bottle pouch, a roomy ball pocket and two velour-lined compartments. The rangefinder pocket has a magnetic closure. These are practical organization details, but the page gives no opening dimensions for the pockets or evidence that a particular rangefinder, jacket or bottle will fit.

The listed weight is 3.4 lb, empty. That is meaningfully below the E-2.5's 4.4 lb listing, but a one-pound difference in the bags does not predict the difference once clubs, balls, water and clothing are added. The manufacturer calls the E-1.5 lightweight and says it is made for the carry golfer; the page does not publish a loaded-carry result or a fit guide for different torso shapes. If you walk regularly, compare the strap geometry in person with a realistic set rather than choosing on the number alone.

Read the storage and weather labels literally

The E-1.5 page lists 16.8 L as “Capacity,” not pocket volume. This site therefore leaves its pocket-volume field unknown and does not let 16.8 L satisfy the finder’s minimum-pocket-volume question. The distinction matters when comparing this bag with manufacturers who explicitly label a figure as pocket volume: a capacity label may describe something else, and neither label tells you the shape or access of each pocket.

Sun Mountain describes the fabric as high-strength Cordura nylon ripstop and claims water resistance. That is a manufacturer material statement, not a waterproof rating or an independently measured rain result. A matching rain hood is listed as included on the current product page, which is more specific than a rain-hood pocket alone; nevertheless, confirm the exact included-items list if buying a retailer package rather than directly from the manufacturer. The page does not specify seam construction or a waterproof rating for the bag body.

Carry use is clear; cart use is not documented here

The E-1.5’s page presents it as a bag for the carry golfer and lists the dual straps. It does not identify this exact model for cart use or list a cart-strap channel. That is why this assessment supports walking but not the finder’s cart or both-modes choices. This is an evidence boundary, not a claim that no owner could ever place the bag on a push cart. Check the manufacturer’s current guidance and your cart’s strap route, stand clearance and pocket access before relying on it for that routine.

The E-Series collection lists an Eclipse Single Strap Accessory separately, and the accessory page says it is compatible with the Eclipse Series. It is an optional alternative to the bag’s dual straps, not an included one-strap configuration. The accessory is separately excluded from this site’s bag catalogue because it is a strap rather than a complete club bag. Confirm the exact product and instructions if you want to change the carry arrangement.

Where it sits beside the E-2.5

The E-1.5 is the lighter, less pocket-dense specification: 3.4 lb and seven pockets versus the standard E-2.5’s 4.4 lb and nine. Both have a four-way top and list a liter figure as “Capacity,” so neither currently qualifies for this site’s pocket-volume filter. The E-2.5 page adds explicit language about being suitable to push or ride, while the E-1.5 page emphasizes carry. The models also differ in fabric claims and top dimensions; their names do not justify carrying one bag’s attributes over to the other.

Choose the E-1.5 for further consideration if its lighter published empty weight, carry-first positioning and included rain hood align with your priorities. Look elsewhere or compare the E-2.5 if two extra pockets and explicit manufacturer language about pushing or riding matter more. In either case, try your clubs in the top, account for loaded weight, verify the exact finish/SKU and check whether the seller’s package matches the manufacturer page. No hands-on carry, weather, fit or durability testing is claimed in this research-based assessment.
